What plant tissue performs the function of photosynthesis and gas exchange?

The main tissue performs the function of photosynthesis and gas exchange. It is also called assimilatory or chlorenchyme. It is located in the pulp of the sheets. It has a green color due to the presence of chloroplasts in the tissue cells. They also carry out the synthesis of organic substances. The cells of this tissue absorb both carbon dioxide and oxygen. The same gases are emitted into the atmosphere. They need carbon dioxide for photosynthesis. Oxygen is released during a chemical reaction. In the dark, plants absorb oxygen from the atmosphere to support various vital processes.
