Detailed explanation-1: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.

Detailed explanation-2: -Cells in the mesophyll of the leaf have numerous chloroplasts. In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis.

Detailed explanation-3: -The palisade mesophyll layer is just below the upper epidermis. It is made up of closely-packed, elongated cells. These cells contain chloroplasts . They perform most of the photosynthesis.

Detailed explanation-4: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
