Vascular Plant Resource Acquisition and Transport

Question 1

Apoplastic route

Answer 1

transport route through the cell wall continuum

Question 2

Symplastic route

Answer 2

transport route through the cytosol continuum, passages constructed in cell wall

Question 3

Simple diffusion

Answer 3

gases and liquids move from high pressure into the low pressure cell interior

Question 4

Facilitated diffusion

Answer 4

polar molecules that can’t make it through the membrane utilize transport proteins and the pressure gradient to enter the cell

Question 5

Coupled transport

Answer 5

H+ proton pumps create a net negative inner cellular charge which causes positively charged molecules to flood in, bringing the desired molecule

Question 6

NO3- membrane transport

Answer 6

requires H+ protons to perform coupled transport into the cell

Question 7

K+ membrane transport

Answer 7

facilitated diffusion on of the cell

Question 8

Aquaporin channels

Answer 8

osmosis is performed through these channels as a form of facilitated diffusion

Question 9

Casparian strip

Answer 9

impermeable strip that forces fluids from the apoplastic route into the symplastic to force filtration

Question 10

Transpiration

Answer 10

water evaporate from leaves which pulls water into the leaves to replenish the low water potential and cohesion forces the rest of the water upwards

Question 11

Stomata

Answer 11

open and close for gas exchange
