Detailed explanation-1: -1: Structure of a leaf (cross-section): Photosynthesis takes place in the mesophyll. The palisade layer contains most of the chloroplast and principal region in which photosynthesis is carried out.

Detailed explanation-2: -You should notice that the vast majority of chloroplasts are found in the cells of the mesophyll. Even more specifically, the palisade layer has the most chloroplasts, so the greatest amount of photosynthesis occurs in that leaf layer.

Detailed explanation-3: -Photosynthesis occurs within organelles called the chloroplasts that are abundant on the leaf of a plant, giving it its signature green pigment. Of course, the leaf is not the only photosynthetic part of the plant; it’s just where most of it happen most of the time.
