Mesophyll is the internal ground tissue located between the two epidermal cell layers of the leaf; and is composed of two kinds of tissues: the palisade parenchyma, an upper layer of elongated chlorenchyma cells containing large amounts of chloroplasts; and the spongy parenchyma, a lower layer of spherical or ovoid cells with few chloroplasts and very prominent intercellular air spaces (Fig. PICTURE mesophytic leaves The leaves of plants that grow under moderately humid conditions with abundant soil and water. The mesophyll is typically separated into two different types of materials called palisade and spongy parenchyma. It is also the name of a disorder of fruit ripening which can reduce the value of a fruit yield, especially in mango. Small veins of the leaves that are more less completely embedded in mesophyll tissue. The two-step process by which 4-carbon compound oxaloacetate is produced in the mesophyll cells and transported into bundle sheath cells of chloroplast in Crassulacean acid metabolism (CAM) plants is called the C4 pathway in mesophyll cells. The chloroplasts in these cells absorb a major portion of the light energy used by the leaf. Whats people lookup in this blog: The cells of the mesophyll contain the photosynthetic pigments.

In addition, they are the channels through which water is released from leaves to the environment. In plants, chloroplasts occur in all green tissues, though they are concentrated particularly in the parenchyma cells of the leaf mesophyll. In the alphonso mango variety, this problem is particularly common, giving soft, white, 'corky' tissue.
