As we all know, all green plants are inseparable from photosynthesis to produce the nutrients needed for their own growth, so what is the role of plant growth boxes?
1. Manufacturing organic matter. The amount of green plants that make organic matter through photosynthesis is huge. It is estimated that the green plants on the earth produce about 400-500 billion tons of organic matter every year, which far exceeds the total annual output of industrial products on the earth. Therefore, people compare green plants on the earth to huge "green factories". The survival of green plants is inseparable from the organic matter produced through photosynthesis. Food for humans and animals also comes directly or indirectly from organic matter produced by photosynthesis.
2. Convert and store solar energy. Green plants convert solar energy into chemical energy through photosynthesis and store it in organic matter made by photosynthesis. Almost all living things on the earth directly or indirectly use these energies as energy sources for life activities. The energy contained in fuels such as coal, oil, and natural gas is, in the final analysis, stored by ancient green plants through photosynthesis.
3. Make the content of oxygen and carbon dioxide in the atmosphere relatively stable. It is estimated that the oxygen consumed by all organisms in the world through respiration and the oxygen consumed by burning various fuels averages 10,000 T / s (tons per second). At this rate of oxygen consumption, the oxygen in the atmosphere will be used up in about two thousand years. However, this situation did not happen. This is because green plants are widely distributed on the earth, continually absorbing carbon dioxide and releasing oxygen through photosynthesis, thereby keeping the content of oxygen and carbon dioxide in the atmosphere relatively stable.
4. It plays an important role in the evolution of living things. Before the emergence of green plants, there was no oxygen in the earth's atmosphere. It was only after 2 to 3 billion years ago that green plants appeared on the earth and gradually became dominant, the atmosphere of the earth gradually contained oxygen, so that other aerobic respiration organisms on the earth could occur and develop. Because part of the oxygen in the atmosphere is converted into ozone, ozone forms an ozone layer in the upper atmosphere, which can effectively filter out the ultraviolet rays that have a strong destructive effect on organisms in solar radiation, so that aquatic organisms can gradually live on land. After a long-term biological evolution process, various animals and plants widely distributed in nature only appeared
