Question 1

Water potential

Answer 1

The potential energy of water compared to pure (0 is highest)
Predicts movement
High to low
Equal to pressure potential

Question 2

Variable water potential

Answer 2

Solution concentration
Pressure potential

Question 3

Macronutrients

Answer 3

Large amounts
Required complete life cycle
Build proteins, Na, Organic molecules

Question 4

Micronutrients

Answer 4

Small quantities
Catlyze reactions

Question 5

Molecule Pathways in Plants

Answer 5

Symplastic - inside membrane
Apoplastic - cell wall extracellular space
Transmembrane - out of the cell into a new cell

Question 6

Fungi and Bacteria assist.

Answer 6

N2 - ammonia
Increase surface area of nutrient uptake

Question 7

Transpiration - Tension - Cohesion model

Answer 7

Transpiration - water leaves through the leaves’ stomata causing a decrease in pressure in that area (high to low)
Tension - causes the water to be pulled up toward the lower area
Cohesion - water sticks to itself, causing one module to drag the other

Question 8

Stomata open/close

Answer 8

Guard cells become turgid due to water uptake and cannot move, so they bend outward (open). Open = gas exchange and loss of water

Guard cells deflate once water realses (flaccid). This causes them to bend back inward (close). Close = prevention of water loss

Question 9

C3

Answer 9

Normal photosynthesis Calvin and Carbon fixation

Question 10

C4

Answer 10

Separate the Carbon fixation and the light-dependent reactions.

Question 11

Cam

Answer 11

Stomata opens night / close day. - temporal reactions

Question 12

Pressure flow model

Answer 12

Sugar collected at source (leaves)
Uptake in water creates osmotic pressure (bringing on water) (Sucrose + H20)
the pressure pushes the sap downward
sugar is then take out of water by cells and stored in sinks (Sucrose)
