Question 1

What are the stages of transpiration?

Answer 1

•Water constantly evaporated
•creates conc gradient more water in roots than leaves so the water travels by osmosis from high conc in leaves to low conc in water
•as more water moves up from roots to leaves by going up the xylem cells water is drawn up then eventually evaporated or transpired at the leaves
remember to say it goes up xylem

Question 2

Factors affecting transpiration

Answer 2

Light intensity= inc
temperature  increase = inc
air movement fast =i nc
humidity falls( drier air)= inc cos osmosis higher conc in leaf than outside leaves

Question 3

what is the process of translocation?

Answer 3

phloem cell arrange in phloem tubes with pores which enables the movement of sap around the plant which contains glucose
