What are the wonders of plants?

The most natural product, the existence of plants itself is a miracle, in addition to which plants have many wonderful skills.

1, plants have the ability of photosynthesis-that is, they can use light energy and chlorophyll that animals don't have, and use water, minerals and carbon dioxide for photosynthesis, releasing oxygen and producing glucose, an energy-rich substance for plants to use.

2, respiration, this ability is an important part of higher plant metabolism. Is closely related to the life activities of plants. Living cells continuously decompose substances through respiration, providing energy for various life activities in plants and raw materials for synthesizing important organic substances, and also enhancing the disease resistance of plants. Breathing is the center of plant metabolism.

3. Some botanists found that they all have their own unique "emotional world" and obvious regularity when studying the thickening speed of plant trunks. Plant trunks have a strange phenomenon similar to human "pulse", which is caused by water movement in plants. After accurate measurement, scientists found that when the roots of plants absorb as much water as the leaves transpiration, the thickness of the trunk is basically unchanged. However, if the absorbed water exceeds the transpiration water, the trunk will become thicker, on the contrary, the trunk will shrink when there is water shortage. Knowing this truth, the "pulse" of plants is easy to understand. At night, the stomata of plants are always closed, which greatly reduces the transpiration of water, so the trees become thicker. During the day, most stomata of plants are open, water transpiration increases, and the trunk tends to shrink. Quite a few woody plants have this phenomenon, but the "pulsation" phenomenon is particularly obvious in some fast-growing broad-leaved trees.
