Gas Exchange In Plants Flashcards
1
Q
How is the structure of the leaf adapted for gas exchange?
A
Large surface area for diffusion
The presence of stomata in he leaf
Short distance that fades have to diffuse across from the photosynthesis cells to the air spaces in he leaf
2
Q
Stomata
A
Allows the movement of gases into and out of the leaf
3
Q
Guard cells
A
Open and close stomata, control gas exchange
4
Q
Spongy mesophyll layer
A
Allows the movement of gases through the leaf TO and from cells. Increases surface area for gas exchange.
