The Leaf Flashcards
1
Q
Waxy Cuticle
A
Clear which allows light to enter, reduces evaporation of water
2
Q
Epidermis Upper
A
Provides protection from viruses and bacteria by providing another layer
3
Q
Epidermis Lower
A
Contains stomata allowing gases to move in and out of leaf
4
Q
Palisade Mesophyll
A
Tightly packed with lots of chloroplasts so photosynthesis can occur, upright positioning allowing light to enter
5
Q
Spongy mesophyll
A
Loosely packed so gases can diffuse in between cells, space for gas exchange, irregular shapes
6
Q
Air spaces
A
Allows movement of gases between cells
7
Q
Veins – xylem
A
Carrys water, long, thin tubes with no proper end walls
8
Q
Veins – Phloem
A
Carrys glucose, sieve tubes with sieve plates in between them
9
Q
Stomata
A
- Pores to allow movement of gases in and out of leaf
10
Q
Guard cell
A
Opens and closes stomata
11
Q
Chloroplasts
A
- Contains chlorophyll, main site of photosynthesis
