DENDROLOGY

Detailed explanation-1: -Chloroplasts are mainly contained in the mesophyll cells located between the upper epidermis and the lower epidermis (i.e. in palisade cells and spongy cells) of leaves.

Detailed explanation-2: -The function of the palisade layer, which is also called the palisade mesophyll, is photosynthesis because it contains most of the chloroplasts in the leaf which maximize energy production during photosynthesis.

Detailed explanation-3: -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-4: -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, converting the energy in light to the chemical energy of carbohydrates.

Detailed explanation-5: -Cells of the palisade parenchyma contain three to five times as many chloroplasts as those of the spongy parenchyma.
