Mesophyll (from the Greek words "mesos" - middle and "phyllon" - leaf) is the internal tissue of a plant leaf, consisting of thin-walled cells that are rich in chloroplasts. This tissue plays an important role in photosynthesis, the process by which plants convert solar energy into chemical energy, which they use for growth and development.
Mesophyll is found between the leaf epidermis (the upper and lower layers of cells that cover the surface of the leaf) and the veins (structures that carry water and nutrients from the plant root to the leaf). Mesophyll is generally divided into two main categories: palisade mesophyll and spongy mesophyll.
The front garden mesophyll consists of long, thin cells that are parallel to each other and are located closer to the epidermis of the leaf. These cells contain many chloroplasts and perform the main function of photosynthesis. They also give the leaf its characteristic green coloration.
Spongy mesophyll consists of shorter, thicker cells that are more loosely arranged and closer to the veins of the leaf. These cells have fewer chloroplasts, but they are more breathable and provide the leaf with the necessary ventilation and gas exchange. Spongy mesophyll also functions as water and nutrient storage.
Both types of mesophyll play an important role in the plant's life cycle and ensure the efficiency of photosynthesis. To ensure plant health, it is necessary to pay attention to their mesophyll and ensure its optimal conditions, including sufficient soil and air moisture, as well as proper lighting.
