Plants and animals are organic nature. On the Earth plants make one third. Animals and man will not live without plants, because the cycle of nature links them. This natural process gives man and animals oxygen and food. The Sun gives energy for this process. Plants are special living things: they accumulate sunlight and make organic matter from inorganic in their leaves. Plants use sunlight and make their food; they give off oxygen into the air during this process. Man and animals breathe out carbon dioxide, which plants combine with sun energy, water and minerals from the soil and in this way make their food. After plants and animals die, rotting process will give back minerals to the soil, where plants will again use them. Plants also play a very important part in conservation and protection of soil, water and animals. They protect soil from the wind and keep water in the soil. Trees give off a lot of oxygen into the air. For example, a hectare of pine forest gives oxygen for ten people. It is necessary to have 1000 square kilometers of forest for ten million people. If there are many parks and trees in a city and many forests around it, then its population will have enough oxygen to breathe.

Text 12. Plants life.
The Sun provides almost all of the energy on the Earth. Plants get energy from sunlight using chlorophyll. This substance gives most plants their green colour. They use the energy to make food in a complex chemical process called photosynthesis - the word means “making things with light”. The simplest plants are algae. They have no roots, stems or leaves and most of them are made of just one cell. Plants similar to today’s single-celled algae evolved in water more than two and a half billion years ago. Algae in oceans carry out most of the photosynthesis on earth. The algae float in the surface waters and form part of what biologists call “plankton”. Plankton is the basis of all nutrition in the sea. It even feeds some of the great whales. The flowering plants are the most advanced of all plants. Just as the mammals dominate the animal world, so the flowering plants dominate the vegetable world. Nearly every plant we see around us is a flowering plant. There are 250.000 different kinds, and they include all the most useful plants as well as the most attractive ones.
