HORTICULTURE

Detailed explanation-1: -The process of photosynthesis occurs in a middle layer called the mesophyll. The gas exchange of carbon dioxide and oxygen occurs through small, regulated openings called stomata (singular: stoma ), which also play a role in the plant’s regulation of water balance.

Detailed explanation-2: -Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, maximizing the production of energy, converting the energy in light to the chemical energy of carbohydrates.

Detailed explanation-3: -Palisade mesophyll cells are tall and have large number of closely packed chlorophyll molecules to absorb maximum light. Most photosynthesis takes place in the palisade cells.
