Name the organ of a plant, the structure in it, the connection with photosynthesis.

Only the green parts of the plant can photosynthesize. These are leaves and, in some cases, stems. All thanks to the presence of chloroplasts in the cells of leaves. These are membrane organelles that provide the synthesis of glucose from inorganic substances under the influence of light. Chloroplasts absorb carbon dioxide and water. In the course of a biochemical reaction, glucose and oxygen are formed. Oxygen is released into the atmosphere through the surface of the leaves, since it is a by-product of the reaction, which is released quite a lot, and it does not accumulate in the cells.
