lesson 9- transport in plants

Question 1

cohesion

Answer 1

attraction of water molecules to other water molecules

Question 2

adhesion

Answer 2

the attraction of water molecules to molecules of other substances

Question 3

root pressure

Answer 3

ions actively transported into root cells where water follows the ions into the root creating pressure forcing water up xylem

Question 4

transpiration (tension)

Answer 4

water leaving plant through stomata and lenticels creating tension and helping to pull water out

Question 5

tonicity

Answer 5

measurement of osmotic pressure of a cell relative to its environment
(basically hypertonic, hypotonic, isotonic)

Question 6

plasmolysis

Answer 6

cells lose water to a hypertonic environment.

Question 7

what happens to plant cells when plasmolysis occurs?

Answer 7

cell membranes pull away from cell wall, causing plants to go limp

Question 7

sink

Answer 7

site where glucose is store/used

Question 8

source

Answer 8

site where glucose is produced

Question 8

if water is provided vacuoles do what?

Answer 8

they re-swell and plants become swollen
