Place the vessel containing the aquatic plant Elodea under a bright light. You will soon see tiny oxygen bubbles appear in the water and rise upward. Why is oxygen released?
All plants and algae contain chlorophyll, which gives plants a green color. This substance absorbs solar energy, due to this, a process called photosynthesis takes place in plants. Photosynthesis is the transformation of simple compounds by plants, such as carbon dioxide, water, and others into organic compounds that are necessary for their vital activity. As a result of the transformation, oxygen is released into the environment. That is, plants breathe, but not like us, absorbing oxygen and emitting carbon dioxide, but on the contrary, using carbon dioxide and emitting oxygen. It is not in vain that forests and plants are called the lungs of the Earth.
