Arm palisade:
Arm palisade is a layer of cells that is located below the epidermis of a plant, this contains cells that has a large number of chloroplasts and thereby trap maximum amount of sunlight for photosynthesis.
They are mostly found in the dicot plants. They have a unique cylindrical structure that has a wide surface area and thereby absorbs more amount of light rays for photosynthesis, hence this is very important for a plant to achieve its photosynthetic rate.
