Q
Upper epidermis
A
- Specialized flats cells
- one cell later thick
- protects inner tissue
- no chlorophyll
1
Q
Cuticle
A
waxy layer that prevents water loss
2
Q
Palisade Mesophyll Layer
A
- rich in chloroplasts
- primary site of photosynthesis
3
Q
Spongy Mesophyll Layer
A
- layer of irregular shaped cells with spaces
- spaces allow diffusion of carbon dioxide
4
Q
Bundle sheath cell
A
- prevents air from entering the xylem
- stores water
- conducts flow of water from xylem to Mesophyll cells and then to the intercellular spaces
5
Q
Xylem
A
transports water
6
Q
Phloem
A
Transports food (glucose)
7
Q
Stomata
A
- spaces in leaf controlled by guard cells
- allows the exchange of moisture and carbon dioxide between the leaf and the atmosphere
8
Q
Lower Epidermis
A
- lower layer
- where stomata and guard cells are located
