A
- epidermal tissues
- palisade mesophyll
- spongy mesophyll
- xylem and phloem
- stomata surrounded by guard cells
2
Q
What are roots adapted for?
A
For uptake of water by
osmosis and mineral ions by active transport
3
Q
What are roots?
A
Roots are adapted organs(root hair cells to increase surface area)
4
Q
What do stomata and guard cells do?
A
Control gas exchange and water loss
5
Q
What does phloem do?
A
Transports dissolved sugars up and down the plant
6
Q
What is translocation?
A
Movement of food molecules through phloem tissue
7
