Leaf structure Flashcards
1
Q
What is the structure of a leaf?
A
Cuticle
Upper epidermis
Palisade mesophyll
Spongy mesophyll
Lower epidemis/guard cells/stomata
2
Q
Cuticle
A
Waxy, hydrophobic layer (prevent water loss)
3
Q
Upper epidermis
A
Protective layer, tightly packed (prevent water loss), clear so sunlight can pass through for photosynthesis
4
Q
Palisade mesophyll
A
Contains many chloroplasts for photosynthesis
5
Q
Spongy mesophyll
A
Loosely packed (intercellular space) to store CO2 for gas exchange
6
Q
Lower epidermis
A
Same as upper
7
Q
Guard cells
A
Control opening and closing of stomata
8
Q
Where are guard cells and stoma located?
A
Lower epidermis
9
Q
Stomata
A
Open and close for gas exchange during photosynthesis.
