Breathing plants

What is the most important process in the world? It is the making of starch by plants. A green plant is Nature’s chemical laboratory. It is able to take carbon dioxide from the air and water from the soil and build them into starch and sugar. The process is made possible by the action of sunlight on the green coloring material of the plant. As you know, it is chlorophyll.

If you have a growing plant at home, preferably ivy or some vine-like plant, try this experiment: fill a test-tube to the very top with water and using your thumb as a stopper turn the tube upside down in a basin of water. Now, being very careful to keep the mouth of the tube under water, take your thumb away and push a branch of the plant up inside the tube then put everything in the sun. In a few hours you will find what seems to be an empty space at the top of the tube. This space is really filled with oxygen which was produced by the action of sunlight upon the leaves of the plant.

Plants are the lungs of our planet. They produce oxygen, enough for all of us to live, and take carbon dioxide from the air. Try to do the experiment and you will see how it works and become more careful with Nature, with plants that are the guardians of our life on this planet.

How do plants eat?

The first two billion years of biological evolution were marked by appearance of all known types of animals and the most advanced forms of plants. During the following 100 million years, till the beginning of Cainozoi era, all the known classes of vertebrate animals as well as sporangia and seed plants were formed.

Life on the Earth starts with the sun, whose energy powers our planet. Traveling some 93 000 000 miles through space, some of the sun’s rays are trapped in the earth atmosphere. These rays are, in a way, food for plant life and for everything that eats plants. Aided by chlorophyll, the green pigment in the leaves, a plant combines solar energy with carbon dioxide taken from the air and water brought up by the roots, to manufacture sugars, starches, and possibly proteins and other materials vital to its life and growth. The growth process is called photosynthesis. The by-product, oxygen, then becomes available to breathe. (And when they breathe, oxidation of food – the reverse of photosynthesis – takes place, releasing energy and making possible all of their life functions such as heat production, movement and growth.) Food energy produced by the plants passes to an animal when the vegetation is eaten, and passes again when the animal is killed and eaten by another. The energy flow through this f o o d c h a i n can even be traced, by marking organisms with radioactive materials, and measured, by calculating the known rates at which oxygen is given off by plants and used up by animals.

elevation and stresses of the land surface – изменения земной поверхности vertebrate animals – позвоночные животные

sporangia and seed plants – споровые и семенные растения carbon dioxide – СО2

starch – крахмал

by-product – побочный продукт, отход f o o d c h a i n – пищевая цепь
