How does the adaptation of leaves allow it to absorb a great deal of sunlight?
-Leaves are often broad and flat giving them a large surface area-The palisade cells near the top of the leaf are packed with palisade cells which chloroplast
1 of 7
How is the spongy mesophyll adapted?
It has air spaces that provide a large surface area for cells to exchange gases with the air
2 of 7
What is the stomata?
Microscopic pores that allow CO2 to diffuse in to the leaves
3 of 7
Which specialised cell open/close the stomata?
Gurad cells
4 of 7
What happen in the light to the stomata?
In light water flows into pores of guard cells making them rigid.This open the stomata.
5 of 7
What happen in the night to the stomata?
At night water flows out of guard cell and there for they lose their rigidity and stomata shuts

Why are leave thin?
So CO2 doesn't have to diffuse far into leaf before reaching the cell that need it.
