Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place. The palisade mesophyll consists of chloroplasts with chlorophyll that absorb the light energy.Continue Reading
The mesophyll layer is made up of the palisade cell and spongy parts. The spongy mesophyll consists of air spaces that aid in the diffusion of gases. The mesophyll region lies directly below the cuticle and the upper epidermis of the leaf.
Some other structures found in a leaf are the lower epidermis, stomata, vascular bundle and guard cells. Each structure plays an important role. For example, guard cells surround stomata and regulate their opening and closing. Stomata are tiny pores that permit gases and other materials to enter into and move out of the leaf. Stomata are found on the leaf's epidermis.Learn more about Molecular Biology & DNA
