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: -Among the layers that make up a leaf are the cuticle layer, the upper epidermis layer, the palisade layer, the spongy layer, and the lower epidermis layer. The palisade layer at the top of the leaf carries out most photosynthesis or absorbs most sunlight.
Detailed explanation-3: -Palisade cells help to absorb the sunlight for the photosynthesis process with the help of chlorophyll. Palisade cells are long and cylindrical in a structure that contains a large number of chloroplasts.
Detailed explanation-4: -Leaves are the principal organs of photosynthesis in most plants. The light reactions of photosynthesis take place most efficiently in the palisade layer, and the light-independent (or “dark") reactions in the spongy mesophyll. Vascular tissues (xylem, phloem) help transport materials within the plant.
