Q

turgid

A

water in cell - mwans well hydrated plant

23
Q

hypertonic outside of cell

A

water wants to move in membrane

24
Q

water freedom is opposite from molarity TF

25
where does water want to move - higher or lower molarity
higher
26
what organelle moderates the turgor pressure
vacuole
27
How do plants regulate osmotic pressure
moving minerals in and out of cells
28
water potential
measure of free energy in water
29
TF water with more solutes has more free energy
false, less free energy like pouring water and syrup
30
TF water wants to move with water potential gradients
T
31
pure water has the highest amt of potential energy TF
t
32
more energy to less energy
T`
33
TF water wants to dilute slutes
T
34
simplistic movement
water move directly from cell to cell passing through membranes
35
apoplastic movement
water moves thorough cell wall
36
3 barriers to water movement
Moving across membrane casparian strip water x pure water
37
aquaporins
proteins in membrane for water
38
TF bc of aquaporins, water can move to xylem
T
39
Is the simplastic pathway or apoplastic pathway conflicting with casparian strip
apoplastic
40
look at diagram of 2 water movement walkways
41
the most permiable place on root
root hair zone
42
are older roots more or less permiable to water
less
43
plant architecture
organization of plant roots
44
hydrotropism
plants responding to moisture
45
chemotropism
plants response to nutrients
46
are diffusion and osmosis passive or active transport
passive higher to lower
47
which way does the gradient go
high to low energy
48
does active transport req energy
yes
49
how do molecules move across a gradient low to high
protein pumps, active trnasport
50
does water enter plants through active or passive transport
active
51
do minerals enter plants through active or passive transport
active or passive
52
TF water soluble molecules still cant enter through water
F it can
53
how does overfertilization occur
water wants to dilute solutes, water comes out of plant bc high energy to low energy water needs to passively move into plants
54
fertilizer burn
too much draws out water from the roots
