A
-Epidermal tissues
-palisade mesophyll
-spongy mesophyll
-xylem
-phloem
-stomata
2
Q
what are stomata surrounded by?
A
guard cells
3
Q
What are roots and what are they adapted for?
A
roots are organs and they adapted for the uptake of water by osmosis and mineral ions by active transport
4
Q
What do the stomata and guard cells in the leaf control?
A
Gas exchange and water loss
5
Q
what does the phloem transport? in which direction?
A
Dissolved sugars up and down the plant
6
Q
What is translocation?
A
The movement of food molecules through phloem tissue
7
Q
what does the xylem transport?
A
Water and mineral ions from roots to leaves
8
Q
what is transpiration?
A
The loss of water at the leaves by evaporation
