Breathing is a complex process that takes place in the cells of a living organism. During this process, under the influence of oxygen, organic matter decomposes into carbon dioxide and water. At the same time, energy is released, which is used by the plant for vital processes.
Plants, like all living organisms, breathe. At the same time, they absorb atmospheric oxygen, and also use the oxygen that is formed in them in the process of photosynthesis and is available in the intercellular spaces.
Plants breathe both day and night.
During the day, most of the atmospheric oxygen enters the plant through the stomata of leaves and young shoots, the skin of young roots, and also the lenticular stems.
At night, almost all plants have their stomata closed, and plants for respiration mainly use oxygen formed during photosynthesis and accumulated in the intercellular spaces. Oxygen penetrates through the intercellular spaces into all living plant cells.
When breathing, complex organic substances break down into simpler ones, from which they were formed – water and carbon dioxide. And the energy of sunlight, which was stored by plants in the process of photosynthesis during the formation of organic matter, is released. The plant uses it for growth, reproduction and other vital processes. Carbon dioxide is removed from the body through the stomata, lentils, or through the entire cell surface of young roots.
Plant respiration is the opposite of photosynthesis. Breathing is an indispensable condition for plant life. Plants receive energy from respiration.
