water x want t move everywhere

Question 22

turgid

Answer 22

water in cell - mwans well hydrated plant

TF water with more solutes has more free energy

Answer 29

false, less free energy like pouring water and syrup

Question 30

TF water wants to move with water potential gradients

Answer 30

T

Question 31

pure water has the highest amt of potential energy TF

Answer 31

t

more energy to less energy

Answer 32

T`

Question 33

Answer 33

T

Question 34

simplistic movement

Answer 34

water move directly from cell to cell passing through membranes

Question 35

apoplastic movement

Answer 35

water moves thorough cell wall

Question 36

3 barriers to water movement

Answer 36

Moving across membrane casparian strip water x pure water

Question 37

aquaporins

Answer 37

proteins in membrane for water

TF bc of aquaporins, water can move to xylem

Answer 38

T

Question 39

Is the simplastic pathway or apoplastic pathway conflicting with casparian strip

Answer 39

apoplastic

Question 40

look at diagram of 2 water movement walkways

root hair zone

Question 42

are older roots more or less permiable to water

Answer 42

less

Question 43

plant architecture

Answer 43

organization of plant roots

Question 44

hydrotropism

Answer 44

plants responding to moisture

Question 45

chemotropism

Answer 45

plants response to nutrients

Question 46

are diffusion and osmosis passive or active transport

Answer 46

passive higher to lower

Question 47

which way does the gradient go

Answer 47

high to low energy

Question 48

does active transport req energy

Answer 48

yes

Question 49

how do molecules move across a gradient low to high

Answer 49

protein pumps, active trnasport

Question 50

does water enter plants through active or passive transport

Answer 50

active

Question 51

do minerals enter plants through active or passive transport

Answer 51

active or passive

Question 52

TF water soluble molecules still cant enter through water

Answer 52

F it can

Question 53

how does overfertilization occur

Answer 53

water wants to dilute solutes, water comes out of plant bc high energy to low energy water needs to passively move into plants

Question 54

fertilizer burn

Answer 54

too much draws out water from the roots
