Contains vessels that transport water and dissolved ions to leaf from roots
1 of 8
Air Spaces
Allows air to come into close contact with cells for gas exchange to 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
Controls the opening and closing of the stomata to allow gas exchange to occur and prevent water loss through 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 gases to penetrate the cells where gas exchange occurs, these cells photosynthesis
6 of 8
Palisade Mesophyll
Regular column shaped cells that are the main photosynthetic cells, these cells contain many chloroplasts that circulate around the cytoplasm
7 of 8
Stomata
Pores found mainly in the lower epidermis that allow gases to enter and leave the leaf. Gases move by diffusion - moving down their concentration gradients.
