2

pterophytes are photosynthetic in which phases

gametophyte and sporophyte

3

water moves into the roots only if the soil's water potential is less or greater

greater

4

cells have a blank water potential than fresh water soil

lower

5

what absorbs most of the plants water and provide great surface area

root hairs

6

what kind of fungi increase root surface area

mycorrhizae

7

what mineral does mycorrhizae help a plant uptake the most

phosphorus

8

xylem has a blank water potential than the root tissue

lower

9

water has blank strength which is why water can defy gravity in the xylem

tensile

10

water molecules blank to one another due to hydrogen bonds

cohere

11

water molecules blank to the walls of the xylem due to polarity

adhere

12

tensile strength of a water column varies blank with its diamater

inversely

13

what can break tensile strength

air bubble

14

xylem has a blank water potential than leaves

higher

15

water vapor leaves the leaf through the blank

stoma

16

the leaf has a blank water potential than the air

higher

17

what manages the rate of transpiration

guard cells

18

closing the stomata can control water loss on a blank basis because they must be open at some point to allow blank in

short term and co2

19

stomata close when

high temps or increased co2 concentrations

20

alternative photosynthetic pathways like cam blank transpiration

reduce

21

stomata opens when guard cells become

turgid

22

when solutes are pumped into guard cells it causes the water potential to blank

decrease

23

abscisic acid causes stomata to blank and causes water to blank because the water potentials blanks

close, move out, increases

24

water moves 1-4 in transpiration

into roots, up xylem, into mesophyll in leaves, evaporates through stoma

25

additional forces to move water other than transpiration

root pressure

26

root pressure causes blank

guttation

27

what is guttation

dew

28

root pressure is blank than transpiration

different

29

three transport routes through cells

apoplast, symplast, transmembrane route

30

movement through the cell walls and the space between cells

apoplast route

31

cytoplasm connected by plasmodesmata

symplast route
