BOTANY

Detailed explanation-1: -Palisade mesophyll-densely packed, columnar-shaped, elongated cells full of chloroplasts. Chloroplasts are structures inside plant cells that contain chlorophyll and are the site of light capture during photosynthesis.

Detailed explanation-2: -Palisade tissue is composed of elongated usually chlorenchymatous cells which occur adjacent to the epidermis or buried more deeply in the cortex or mesophyll of plant stems and leaves. In its commonest form it is made up of cylindrical cells with their long axes at right angles to the surface of the organ.

Detailed explanation-3: -The palisade layer of a leaf is comprised of columnar-shaped cells that contain chloroplasts. Palisade cells are the site of photosynthesis due to the number of chloroplasts in each cell.

Detailed explanation-4: -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-5: -Beneath the palisade mesophyll are the spongy mesophyll cells, which also perform photosynthesis. They are irregularly shaped cells that have many intercellular spaces that allow the passage of gases. There are also guard cells that allow the gases to exchange.
