Detailed explanation-1: -The palisade mesophyll layer is where most of the photosynthesis occurs in the leaf. The palisade cells contain a lot of chloroplasts to help them perform this photosynthesis. The palisade cells are closely packed together to maximize light absorption.
Detailed explanation-2: -Density: The number of palisade mesophyll cells per unit area is deficient, meaning each cell has a high surface-to-volume ratio. This allows for more efficient use of light energy during photosynthesis.
Detailed explanation-3: -The palisade mesophyll layer of the leaf is adapted to absorb light efficiently. The cells: are packed with many chloroplasts. are column-shaped and arranged closely together.
Detailed explanation-4: -These large spaces allow these layers to help carbon dioxide move around the leaf. The spongy mesophyll also allows the plant to bend and move in the wind, which itself helps move gases around the leaf’s cells.
