Topic B: Transport in Plants

Question 1

phloem

Answer 1

transports nutrients made in leaves to rest of plant (translocation)

Question 2

water pathway

Answer 2

root hair -> root cortex cells -> xylem

Question 3

root hairs

Answer 3

increase surface area which allows more water to be osmosis

Question 4

factors affecting rate of transpiration

Answer 4

• wind speed (dry air = easier diffusion)
• humidity (high conc of water in air = less transpiration)
• light intensity (stomata only open/work in light)
• air temp (dry air = easier diffusion)
• # of leaves (less leaves = less transpiration

Question 5

translocation

Answer 5

movement of sucrose & amino acids in phloem

Question 6

xylem

Answer 6

transports water, minerals to stem & leaves
