contains vessels that transport water and dissolved ions to leaf cells from the roots
1 of 8
Air Spaces
allows air to come into close contact with cells so that gas exchange can occur
2 of 8
Upper Epidermis
made of transparent cells so that light can penetrate easily and reach the photosynthetic layer of cells
3 of 8
Guard Cell
control the opening and closing of the stomata to allow gas exchange to occur and to prevent water loss by transpiration
4 of 8
Waxy Cuticle
made of lipid based molecules to prevent evaporation of water from the upper surface of the leaf
5 of 8
Spongy Mesophyll
loosely packed cells to allow air (gases) to penetrate and reach all cells where gas exchange occurs, these cells can photosynthesise
6 of 8
Palisade Mesophyll
regular column shaped cells that are the main photosynthetic cells, these cells contain many chloroplasts that circulate around in the cytoplasm
7 of 8
Stomata
pores found mainly in the lower epidermis (there can be some in the upper epidermis) that allow gases to enter and leave the leaf, gases move by diffusion (moving down their concentration gradients), water is lost via transpiration
