It protects against water loss, regulates gas exchange and produces the waxy substance that becomes part of the cuticle.

Cuticle Wax
This is a protective waxy covering produced on the top and bottom of a leaf. The cuticle tends to be thicker on the top of the leaf.

Palisade Mesophyll
This has cells in whichchloroplasts are especially concentrated in, and it is in these cells that much of the photosynthesis in plant takes place.
6 of 8
Spongy Mesophyll
This consists of irregularly shaped cells. There is air spaces between the cells which allow food-producing cells of the leaf to access the gases so that they can photosynthesis.

Guard Cell
These help to maintain the right rate of transpiration by opening and closing the stomata, by doing this, they prevent excessive water loss.
