Diversity of plants on Earth mosses algae ferns flowering conifers

MHI Mosses are very ancient representatives of the plant kingdom. Mosses grow only in places of increased moisture. They participate in the formation of swamps, the creation of peat, and affect soil moisture.

Ferns These plants are often referred to as living fossils. They need protection. Ferns help scientists understand how the diversity of the plant kingdom of the Earth developed.

ferns

Algae Scientists believe that among the plants existing on Earth, the most ancient are blue-green algae. Their age is about three billion years.

CONIFEROUS PLANTS Differ in special needle-shaped leaves - needles. The needles do not fall all at once, like ordinary leaves, but gradually, over several years. Therefore, coniferous trees all year round green.

In conifers, resin (resin), wood, fruits (for example, pine nuts) are very valuable.

FLOWERING PLANTS Flowering plants now dominate the Earth. They are called so because they have flowers, from which fruits with seeds are formed.

Flowering Plants Flowering plants are the most numerous and widespread group of plants on Earth.

Diversity of plants By 2004, scientists managed to classify about 290 thousand species, including 240 thousand flowering plants, 16 thousand mosses, 11 thousand ferns, 8 thousand green algae. Plants are found everywhere.

Diversity of plants on earth The world Grade 1 Teacher MBOU ESOSH No. 1 Kravtsun M.G. Stanitsa Egorlykskaya, Rostov Region

Ferns Many millions of years ago, these plants dominated the globe. Then ferns were huge trees up to 40 meters high. Currently, drenched ferns can only be found in tropical forests. Herbaceous ferns grow in our country. They are more complex in structure than mosses, since in addition to stems and leaves they have roots.

Coniferous (gymnosperms) Coniferous plants (trees and shrubs) live everywhere in our country. Among them, you are well aware of spruce, pine, larch. Coniferous plants have not only roots, stems and leaves, but also seeds that are located openly (naked) on the cone scales. Coniferous plants propagate by these seeds.

I have longer needles than a Christmas tree. I grow very straight In height. Both in winter and in summer If I'm not at the edge, I'm dressed in a green fur coat. Branches are only at the top of my head. In the Crimea, over the sea, As on patrol, They stand in columns Always green, Wonderfully slender. There are many algae on Earth different types plants. The largest group is algae. These plants have no roots, no stems, no leaves, no flowers. The simplest of them are unicellular algae. They are so small that they can only be seen with a microscope. Despite their small size, in the summer they are easy to spot in the water, because these algae are extremely abundant. In warm sunny days algae multiply very quickly, and the water in which they live turns green. There are also multicellular algae. Especially a lot of them in the seas and oceans. Here they form dense thickets, underwater "forests".

Flowering Now on Earth, most plants are flowering. They are called so because they have flowers, from which fruits with seeds are formed. Flowering plants are the most numerous and widespread group of plants on Earth. They are found everywhere in forests, in meadows, in reservoirs ...

There is a curly hair in the forest - White shirt. Heart of gold, what is it? It is very similar to the animal's mouth, But only it is not dangerous to get into it. Stem - winged, Leaf - mustachioed, flower - fragrant And the fruit is fluffy. Mosses You certainly know about plants like mosses. They can be found in a humid forest, in a swamp, on the trunk of an old tree. They often form a continuous cover of emerald green color on the soil. Moss has only a stem and leaves, but no roots or flowers. Moss is highly dependent on water. They absorb everything like a sponge. If there is little water, the mosses dry up, their life stops. But mosses are very tenacious. Some of them survived after nine years of "imprisonment" in the herbarium.

You are a man Loving nature, Although sometimes feel sorry for her. In pleasure trips Do not trample her fields. In the station hustle of the century You hurry to evaluate her. She is your good old doctor, She is an ally of the soul. Do not burn her recklessly.

For a better study of the material, I propose to conduct a thorough study of each group of plants.

But it will be difficult to study such a large material on our own, so we will divide into groups and work along the route.

Each of you has your own task.

Read the study topic for each group

1 group: With the head, gone under the waves, green between the stones,
We do not have flowers and leaves, to be honest, there are no roots.
We will perish on land: we always live in water.

2 group: Between cranberries and cloudberries, among forest swamps,
Always on moist soil my relative grows.
It may be green or almost gray,
But you have to bend down to meet him.
In the forest, in the damp lowland, you will always meet us,
After all, we need water for our life.

Guess what kind of plants we are talking about?

3rd group: Forest grass - carved foliage,

It does not boast of branches, but is proud of its ancestors -

mighty giants with dense crowns

1 more hint:

I love moisture too.
In the shadows, in the wilderness,
My carved leaves are, of course, good.
But I'm not proud of them!
Our very ancient family
Brings warmth and light from the past of the planet.

4th group:

We are dear to you all with our green view all year round.
We are easy to recognize by the cones and the abundance of resin.
Our leaves are very prickly, they are called needles,
And although we bring joy to you, we never bloom

5th group:

Well, we, and we are with flowers,
We bloom, we give fruits,
We feed the seeds
We will decorate the house.
We are in the forests, meadows and in the field,
We are in the desert and in the water.
By flowers, as by a password,
You will recognize us everywhere

Annex 3

1) Algae.

Algae have neither roots, nor stems, nor leaves, although some large marine representatives of this group of organisms have formations that look like these organs. Why don't algae need roots? Algae do not need roots as they live in solution nutrients and can absorb them with their entire surface

Some algae, mainly seaweeds, have plates shaped like leaves. Seaweeds have been used for a long time and quite widely in human food, as animal feed, as fertilizer, as a raw material for the manufacture of medicines, as well as in the form of bread ingredients, cakes , canned meat, ice cream, jelly and various emulsions. Iodine can be extracted from the bowels of the earth, but almost all over the world it continues to be extracted from seaweed. - Crimson and brown - an ancient group of algae, inhabitants of the seas. In some countries, they are widely used in food as condiments and snacks.
- During the period of mass reproduction of unicellular algae, the water turns bright colors - "blooms", they say. Some algae can even grow on the snow in the mountains or in the polar regions, giving the snow different shades. The snowfields of Greenland sometimes turn yellow, then green, then red. Perhaps this is what Greenland owes its name to (in translation - the green country).

sea ​​kale as medicine was known as early as the 13th century in China. In the XIII century, the Chinese emperor issued a decree obliging the population to systematically eat it as a dietary and prophylactic agent and deliver it for these purposes to settlements at the expense of the state.

The oldest

crossing the Atlantic Ocean, not far from the coast of America, they met with surprise and fear whole fields of floating brown-yellow algae.

2) Mosses. Sphagnum moss grows in swamps. Sphagnum is common name for various (primarily in color) types of moss: “white moss”, “brown moss”, “red moss”, etc. Common to all mosses is that living on very wet soils, they accumulate in leaves and in surface layers stems a lot of water. Mosses do not have roots, and it is thanks to aquifers that sphagnum leaves have a hygroscopic property, that is, they are able to retain water. The word sphagnum in Greek means sponge

Sphagnum mosses play an important role in the formation and life of swamps. Peat deposits are formed from the dead remains of sphagnum. Moss sphagnum grows at the top of the stem, and its lower part dies off ("peat"). This is how huge deposits of peat are formed over many years. Peat is a valuable raw material for obtaining wax, paraffin, ammonia, alcohol, etc. It is used in medicine, in the construction industry, as fuel, fertilizers.

Sphagnum moss is used both in folk and scientific medicine as an antiseptic and dressing material for purulent wounds, as it has the ability to absorb a large amount of moisture.

3) Ferns. Tree ferns are almost extinct, but herbaceous ones feel good in modern conditions. The word "fougère" is borrowed from French and means - fern Leaves sometimes reach one and a half meters, but grow very slowly. Only in the spring of the third year do they reach full development. In autumn, the leaves of our forest ferns tend to die off. Ferns are moisture-loving and shade-tolerant plants. In addition to stems and leaves, they have roots.

Among the Slavs, the fern was a legendary plant - he was credited with witchcraft power. - Ferns are ancient plants. In Rus', there was a legend that the fern blooms with a fiery flower, which blooms once a year in the dead of night under thunder and lightning flashes on the holiday of Ivan Kupala (July 7). On this mysterious night, festivities, round dances were organized, people jumped over fires and went looking for the “fiery fern flower” that opens treasures. It was believed that whoever manages to pick this flower will open all the treasures, he will hear the voices of trees and herbs.

4) Coniferous plants

Conifers- higher plants. They are found throughout the Earth, adapted to adverse conditions. There are over 600 species. They have cones with seeds and pollen. Durable wood is used for construction and in the furniture industry.

Conifers- are woody forms, less often shrubs. These are: spruce, pine, fir, cedar, cypress, larch, sequoia. Their leaves in the form of needles are called needles. There are also deciduous conifers, this is larch. Conifers have cones with seeds from which vitamins and cedar oil are obtained. coniferous forests- keepers of waters, emit a lot of oxygen. Silk, paper, plastics are made from wood.
- These plants are also called gymnosperms, because in addition to the root, stem and leaves, they also have seeds that are located openly (naked) on the scales of cones. The giant sequoia can grow up to about 95 m, and its trunk diameter can range from 5 to 11 m. The largest of these trees is about 4000 years old.

5) Flowering plants

Flowering - the most common group of plants, has about 250 thousand species. Among them are many trees, shrubs, herbs. Found everywhere. Many flowering plants are cultivated and are used by humans as food and medicines. Wild plants are animal feed. Flowering dominate the plant world. And if you admire some beautiful flower - know that the plant is probably a flowering plant.

Plants play a huge role in our life. They are food, industrial raw materials. And herbs play another important role in our lives. Since ancient times, people have known their healing power. Among the wild-growing, the “root of life” ginseng is world famous. No less famous are nettle, plantain, St. John's wort. However, in our country, 500 plant species are on the verge of extinction. Excessive collection of forest and field bouquets served to impoverish plants. The swimsuit, sleep-grass, anemone are leaving us. You rarely see a lily of the valley near the city. The "Red Book" came to the aid of plants. Much depends on us. Resting in the forest, resist the temptation to pick a flower.

Flowering plants don't bloom for humans at all. Bright colors, aroma are necessary for flowers to attract insects.

Only we humans can admire the beauty of flowers. And insects are only interested in color, flower shape and smell. After all, flowers not only lure, they also feed some insects with juice-nectar, others with pollen, and still others with both.

cluster



We have learned the signs of various groups and species of plants, and now we can analyze and generalize new knowledge. Each table has a table. Now you will need, based on the knowledge gained, to fill it out.

Conifers (gymnosperms) Although the total number of species of conifers is relatively small, they play a very important ecological role. Coniferous dominant plants in vast areas of land. Many coniferous plants emit a resin designed to protect the tree from insects and fungi. Resin of fossil trees amber. amber


The use of amber in ancient world Since time immemorial, people have endowed fossil resin, whose age is estimated at millions of years, miraculous properties. A small piece of amber jewelry was often more expensive than a young slave in the slave market, because the delivery of amber to Rome along the Amber Route was fraught with great difficulties. Medicines and ornaments made of fossilized resin were recommended at the most various diseases. Even the Roman scientist Pliny the Elder (2379 AD) was convinced that amber amulets protect against male diseases and mental disorders.






Pea cypress - Chamaecyparis picifera. Of the cypress varieties, only this species can be fearlessly purchased for a garden near Moscow, and even then it is worth choosing a protected quiet place in the garden for it. These are slow growing shrubs with elegant green, blue or yellow needles.






Microbiota - Microbiota decussata, a wonderful, unfortunately little-known ground cover coniferous plant for shade and partial shade, 0.5 m high, spreads, by the age of 10 it will take 1.5-2 m. The needles in summer are very beautiful, dark green, in spring and autumn - reddish-brown. It is not exacting neither to moisture, nor to the soil, does not break with snow. Bad transplant.




Ferns In a dark, shady corner of the forest you can find a large herbaceous plant with dark green oblong leaves and a thick rhizome covered with numerous dry scales. This fern is a very common perennial plant.


Ferns Many probably know about the ancient holiday of Ivan Kupala, or Ivan's day. There was a belief that on the night before Ivan's Day (June 24), the fern blooms only once a year, shining with a fiery flame and illuminating everything around. It was believed that the fern flower has a wonderful property to open treasures. Many tried to find a flowering fern, but no one succeeded because the fern does not bloom at all!


Algae Organisms that are grouped together as algae have a number of common features. In morphological terms, for algae, the most essential feature is the absence of multicellular organs - root, leaves, stem, typical of higher plants. For most algae, water is a permanent habitat, but many of their species can live out of water. MARINE MACROPHYTES are the largest algae in the world. These multicellular organisms resemble green plants more than any other algae.
















Moss habitats Mosses are found on all continents, including Antarctica, often in extreme habitat conditions. Mosses usually form dense clusters in shady areas, often in close proximity to water, although they can also be found in relatively open, dry areas. Among mosses there are species living in freshwater reservoirs. There are no marine life, although some species settle on the rocks in the surf. Moss in the drainpipe in winter.


Green mosses. They are found everywhere: they grow on the soil, tree trunks, rocks and roofs of houses, but are most widespread in damp forests, forming a continuous green carpet. One of the most famous and most common mosses is cuckoo flax, which forms dense tufts of erect, unbranched stems densely covered with narrow linear-lanceolate leaves.


Sphagnum A feature of sphagnum mosses is the continuous growth of the stem at the top and the death of the lower part. However, the complete decay of dead parts does not occur, since there is little oxygen in waterlogged soil. Peat is formed. Sphagnum is a common name for various (primarily in color) types of moss: “white moss”, “brown moss”, “red moss”, etc. Common to all mosses is that living on very wet soils, they accumulate in there is a lot of water in the leaves and in the surface layers of the stems.

And I will begin our lesson with a conversation of one student. And here's what he said:

“I’ll grow up and discover some living creature. Just don’t be late.” To which they replied: “It’s never too late to learn and discover something.” The main thing is to be attentive and observant and you will make many amazing discoveries.

One discovery is already waiting for us today at the lesson.

Actualization of knowledge and problem statement.

On the board slide number 1

What do the objects depicted in these pictures have in common (living beings)

Prove (they breathe, eat, grow, reproduce, age and die)

SLIDE #2

Which picture is missing? (wolf)

Why? (it belongs to the animal kingdom)

To which group would you classify the rest of the pictures? (plant kingdom)

Why? (because they have a root, a shoot, a flower, a fruit with seeds)

Is it possible to list all representatives of the plant kingdom (no)

Why? (there are a lot of them)

Wherever you look, plants are everywhere. Since ancient times, man, collecting and then cultivating plants, learned their useful and harmful properties. This is how the science of plants appeared, the name of which you will learn by solving a crossword puzzle.

The keyword is encrypted vertically.

1)

Tree that bears fruit - acorns (OAK)

Look at the fence

The queen of the garden blossomed.

Not a tulip, not a mimosa.

And in the thorns beauty .... (rose)

Examination

Each group is asked one question, the rest of the groups check.

Slide PARTS OF THE PLANT No. 4

Well done guys, you did a great job.

Do all plants have named parts? (no)

Right. That is why botanists divide the plant kingdom into groups.

What do you think, what goal will we set for ourselves today and will look for answers to it?

The purpose of our lesson is to get acquainted with the groups of plants and the features of their structure, that is, according to what signs scientists divided all plants

Group work. Learning new.

So the guys scientists divided the entire plant kingdom into 5 groups. And which ones you will find out now. Speakers, please give everyone a number. The teacher puts numbers at this time. The first group will study algae, the second group will study mosses, etc.

When they bloom ?

Seaweed - these are lower plants that live in water, in algaethere are no roots, stem, leaves, flowers and fruits with seeds. They absorb everything they need with the entire surface of their body. They can be quite small, in the form of balls. This is chlorella. But also quite large, similar to long threads or ribbons, for example, "seaweed" - kelp.

Mosses. In a humid forest, in a swamp, on the trunks of old trees, mosses can be found. Mosses have stems and leaves, but no roots or flowers. They obtain water and minerals from the stem and leaves. Mosses usually form dense clusters in dark places and close to water.

ferns plants that live in damp shady places. .They have root, stem, leaves. They do not have flowers or fruits. Fern leaves are like feathers. Ferns never bloom. Ferns are herbaceous or tree-like. There are ferns - giants - these are trees up to 200 meters high.

coniferous plants - these are trees and shrubs with leaves-needles. These plants have roots, stems and leaves. They have no fruits and flowers, seeds are formed in cones. Most coniferous trees are evergreen. coniferous trees There are about 600 species. Coniferous plants include - pine, juniper, cedar, spruce.

flowering plants - the most widespread group on the whole Earth. These are plants that have flowers. They have all organs - root, stem, leaves, flower, fruit and seed. These include trees that give fruit (oak, birch, apple tree), shrubs - a dog rose, lilac, currant, herbs (dandelion, strawberry, lily of the valley) and all flowers.

Each group had questions, let's check how you answered the questions. Each group reads the question and answers.

Other groups can ask questions

Well done guys, you have successfully completed this task.
