Detailed explanation-1: -Mesophylls are the internal ground tissue present in leaves. There are two types of mesophyll cells in the leaves namely palisade mesophyll and spongy mesophyll. Mesophyll cells are provided with a large number of chloroplast. Photosynthesis occurs in the chloroplast.

Detailed explanation-2: -In dicotyledonous leaves there are two types of mesophyll cell; palisade mesophyll and spongy mesophyll. Palisade mesophyll cells are elongate and form a layer beneath the upper epidermis, whereas spongy mesophyll cells are internal to the lower epidermis.

Detailed explanation-3: -Spongy tissue is a type of tissue found both in plants and animals. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf. The spongy mesophyll’s function is to allow for the interchange of gases (CO 2) that are needed for photosynthesis.
