It protects against water loss, regulates gas exchange and produces the waxy substance that becomes part of the cuticle.
It serves as protection like skin, and also helps retain moisture.
Mesophyll is the material that makes up the majority of a plant's leaves. It is a simple fluid that is extremely important and is mostly responsible for making plant life possible.
The stoma is an opening on the bottom of a leaf which takes in carbon dioxide from the air and releases oxygen and water.
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.
This has cells in which chloroplasts are especially concentrated in, and it is in these cells that much of the photosynthesis in plant takes place.
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.
These help to maintain the right rate of transpiration by opening and closing the stomata, by doing this, they prevent excessive water loss.
