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