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: -In a nice organized order we find the palisade parenchyma cells of the mesophyll. These cells have a lot of chloroplasts in them, which is why they’re the main sites of photosynthesis in the leaf (since chloroplasts conduct photosynthesis).
Detailed explanation-3: -The palisade layer has more chloroplasts than the spongy layer. This makes sense since the palisade layer is located on the top of the leaf and thus comes into contact with more light than the spongy layer. The spongy layer is more important for gaseous exchange.
