1
Q
Role of Palisade mesophyll cells
A
they do most of the photosynthesis
2
Q
How is the structure of Palisade mesophyll cells adapted to perform its function?
A
> They contain many chloroplasts, so they can absorb a lot of sunlight.
The walls are think so carbon dioxide can easily diffuse into the cell
3
Q
Role of Root hair cells
A
They absorb water and mineral ions from the soil
4
Q
How is the structure of Root hair cells adapted to perform its function?
A
> They have a large surface area for absorption and a thin, permeable cell wall, for entry of water and ions.
The cytoplasm contains extra mitochondria to provide the energy needed for active transport
5
Q
Role of Guard cells
A
Exchanges gases for photosynthesis
