Let's discuss it together
Question: “Without plants, life on Earth would be impossible. Man cannot live without plants." What evidence can be provided to confirm or refute these assumptions? Let's compare your answers with the text.
Answer: plants inhabited our planet long before people appeared on it. Since then, they have lived on a variety of land areas, sometimes poorly adapted for life. They grow in the tundra, forests, steppes, and deserts. They inhabit lakes, rivers, seas and oceans. Plants can be found even on bare rocks and shifting sands.
Plants are essential for human life, as they produce oxygen necessary for breathing; domestic and wild animals feed on plants.
Herbs, trees, and shrubs cover the ground with a dense living carpet, protecting it from drying out. In tree thickets a softer, humid microclimate is created, since the foliage does not allow hot sun rays dry up the earth. Their roots hold and hold the soil together.
Extremely important function green plants - the implementation of a biological process called photosynthesis. This process is extremely important for the existence of all life on this planet. Through photosynthesis, plants have the ability to create carbon dioxide and water, organic substances that are necessary for plant products food - vegetables, fruits, grains, legumes, etc. Plants are also used as raw materials for industry, construction, and medicine.
The formation of the gas composition of the atmosphere is also directly dependent on plant life. Thanks to photosynthesis, plants release into the atmosphere a huge amount of oxygen necessary for all living things. They increase soil fertility thanks to humus. With their roots, they suck out some of the minerals from the soil, after which they pass them on to animals as food. Plants play a huge role in the life of nature, influencing climate formation, water sources, animal life, as well as other components of the biosphere.
Question: Explain why the forest is called “the lungs of the Earth.” Where is it easier to breathe: near a highway or in a meadow? Why?
Forests are called “the lungs of the Earth” because forests, being air purifiers from the main pollutant - carbon dioxide, absorb it from the atmosphere and produce oxygen necessary for the life of all life on Earth.
It’s easier to breathe in the meadow than near highways, because... cars passing over them emit a lot of harmful substances creating the so-called “air pollution”. Plants growing along highways absorb a small amount of harmful emissions, and accumulate them in their composition (leaves and fruits), so you cannot collect mushrooms and berries that can grow along the roads.
In meadows far from highways, there is no air pollution from automobile exhaust gases, plants produce oxygen, the air is clean and easy to breathe.
Question: Tell us which plants “feed” a person, which ones “treat”, which ones “dress”.
Answer: Plants that “feed” a person, those that can be eaten, there are a great many of them. To give an example, here are just a few: vegetable plants: tomatoes, cucumbers, cabbage, carrots, beets;
fruit trees: apple, pear, plum, orange and tangerine trees;
cereal plants from which we obtain cereals: semolina, buckwheat, rice, wheat flour;
There are also a lot of medicinal plants; dry tea mixtures, tinctures, ointments, and concentrates for making tablets are made from them. Let's give examples medicinal herbs and tree fruits: plantain, pink radiola, ginseng root, chamomile, sea buckthorn, calendula, raspberry, aloe;
Plants that “dress” a person include those from which fiber is made to make fabric. The main plants are flax and cotton. But fabrics can be obtained from bamboo, nettle (the fabric is called “ramie”), and jute.
Homework:
Question: Look at the pictures. On what basis can plants be divided into groups? Describe one of these groups.
Answer: *Plants will be correlated according to the following criteria: cultivated and wild
Cultivated plants: garlic, cauliflower, buckwheat, cotton, flax, sea buckthorn.
Wild plants: rose hips, chamomile, birch, oak, cedar pine.
Vegetable world, or the flora of the Earth - the totality of all types of nuclear, multicellular, photosynthetic plants found in. Most organisms are those that synthesize their food using solar energy, but there are also heterotrophic plants and very few species that are both autotrophs and heterotrophs. The history of life on Earth and the existence of many organisms literally depend on the life of plants. Since animals cannot obtain energy directly from the Sun, they must eat plants (or other animals that have a herbivorous diet) to survive. Plants also provide oxygen to people and animals because they absorb carbon dioxide and release oxygen into the atmosphere.
Plants are common on land, in the oceans and in fresh water. They have existed on our planet for millions of years. Number of species currently existing green plants presented in the following table:
The table shows the total quantity various types green plants ( Viridiplantae). It is estimated that there are about 300,000 living species Viridiplantae, of which 85-90% are flowering plants. (Note from the author: Because the data is taken from different sources and has different dates, in some cases the estimates are subject to some uncertainty)
Eucalyptus regal
The flora of Australia is characterized by the presence of a large number of endemic species - plants that are not found anywhere else. Nevertheless, with the advent of settlers, many other “non-native” species took root on the mainland. Australian vegetation is characterized by the predominance of two types of plants - eucalyptus and acacia.
Asia has the greatest diversity of flora of any part of the world, as it occupies the most large area, is located in different climatic zones and natural zones. Here you can find more than 100 thousand species of plants, from tropical to arctic, which makes up about 40% of the Earth's flora. The mainland also has a large number of endemic plants.
Colobanthus Quito
Antarctica is the most inhospitable place on Earth for both plants and plants. There are no trees here, but only two types of flowering plants and many mosses, lichens, algae, etc. The continent is very fragile and is suffering due to climate change and human activities.
Euphorbia thorn
Africa is the second largest continent in the world and is home to many unique plants. The flora of the mainland is divided into three main ones -, and. At the same time, they do not have a wide species diversity, because this biome is characterized by complex climatic conditions, including high temperatures and drought. The Sahara Desert, located in northern Africa, is one of the driest places on Earth. However, African wet evergreens contain a wide variety of plants.
Despite the fact that Europe is located on the same continent as Asia, called Eurasia, it does not have such a rich species diversity of flora as its eastern neighbor. The flora of Europe is largely influenced by the Alps mountain range, which stretches from west to east.
In the territory North America The main biomes of the planet are located, from deserts to arctic tundras. Each biome is characterized by a collection of certain plant species that have adapted to grow in certain environmental conditions.
South America, like Asia, is home to a huge variety of plant species. There is a huge ecosystem here that supports the life of many plants.
Plants serve as the foundation of all life on Earth and are important and necessary for human well-being. Think about how your everyday life depends on the plants.
Amazon rainforests
Environment and climate are largely interconnected with flora. Precipitation, humidity and temperature depend on the presence and nature of vegetation. The reduction of plants also disturbs the balance in and indirectly affects human life.
Deforestation
There are a huge number of species of flora on our planet, both recorded and unstudied or even unnamed. However, while the threat to the existence of many wild animals is now widely recognized, few people know that plants are also in great danger. In February 2015, the Center for Biological Diversity stated: "Of more than 300,000 known species Plants The IUCN has assessed only 12,914 species, finding that about 68% of the plant species assessed are at risk of extinction."
Vast areas of deserts around the world indicate the destruction of vegetation by humans. Much of the Middle East is now desert or is being redeveloped at great expense. Once upon a time there were many forests in the Mediterranean, now these lands are bare and eroded. In many parts of Africa and India, cattle and goats wander the rocky plains, eating any patch of greenery that appears in the barren lands that were once good pasture. Overgrazing by domestic and wild animals is, in fact, the biggest threat to plants, although "raids" of botanists and other enthusiasts on some beautiful plants sometimes entail serious losses for rare species.
Perhaps people forget that we are all cultivated plants and garden flowers come from wild flora. Equally important is the fact that plants provide a high proportion medicines V modern world. Who knows what secret treasures for humanity are still locked away among the vegetation, waiting to be discovered. Tropical rainforests are among the most vulnerable habitats on the planet, containing 63% of the world's most threatened plant species.
One of the most serious threats to flora is the conversion of natural habitats into areas for agricultural use and livestock farming, for example when rainforests destroyed for grazing or growing soybeans, animal feed, or oil palms. Ancient woodlands are special because they have been standing for at least 400 years and provide the basis for biodiversity as well as supporting abundant wildlife.
Plant protection is a set of measures aimed at protecting existing plants and especially endangered species. The main document that lists plants that are subject to protection is the IUCN (International Union for Conservation of Nature) Red Book.
The IUCN Red List has clear criteria for assessing the extinction risks of thousands of species and subspecies. These criteria are relevant for all species and regions of the world. The goal is to convey the importance of conservation issues to the public and national governments, and to help the international community try to reduce species extinction. According to the IUCN, the stated objectives of the Red List are to:
One of the most important conservation actions is the creation of national parks, nature reserves, nature reserves, botanical gardens, etc. These environmental sites make it possible to preserve natural environment plant habitats and protect them from overexploitation by humans.

Plants are the first step in the food chain
Answer from Siatkoq Karomel[newbie]
Vegetation cover is also of great importance as a source of oxygen, without which life on Earth is impossible. Green plants release huge amounts of oxygen into the atmosphere.
One average-sized tree produces enough oxygen per day to breathe for three people. And how much does one hectare of forest produce, an entire forest area, all the forests of the globe!
Green plants play an extremely important role in one more respect: they, and only they, are capable of absorbing carbon dioxide from the atmosphere on a large scale and, therefore, preventing its accumulation in the atmosphere. air envelope of our planet. An increase in carbon dioxide in the Earth's atmosphere would have the most detrimental consequences.
Many examples can be given showing how great the role of vegetation is in the life of nature. Without the participation of vegetation, the process of soil formation is impossible - one of the most important processes flowing on Earth. Without plants, the life of wild animals is impossible - not only herbivores, but also predators. Vegetation cover prevents the erosion of river banks and mountain slopes, sand blowing, etc. Vegetation affects the atmosphere and soil, groundwater And animal world, streams and rivers, lakes and swamps. In other words, this is a powerful natural factor, the importance of which is difficult to overestimate.
