10/22 Plant transport Flashcards
from where do plants acquire their nutrients from where?
soil and air
CO2+light+water—-> photosynthesis —–>
glucose C6H12O6+O2 gass
what does a plant do w/ the minerals it absorbs from the soil?
it transports to the leaf
3 main minerals that plants need
Nitrogen, Phosphorous and Magnesium
Osmosis (Def)
diffusion of water
passive transport
does not require energy (Diffusion and Facilitated diffusion)
facilitated diffusion
proteins help move molecules more quickly
Diffusion
moving of molecules from an area of low concentration to an area of high concentration.
active transport
using of energy to move something
What controls mineral uptake ?
plasma membranes of root cells
mass of plants comes from?
water
TorF: do roots exert pressure?
T
what ion opens the stoma?
K+ and water
what ion leave to close the stoma?
K+ and water
TorF: can moss add ions to open stomata?
T
Phloem transport what?
sugars
where does the cactus do photosynthesis?
in the stem
when a plants lacks certain minerals what does it do?
eats insects as supplements
intracellular route
crosses the cell wall and plasma membrane of an epidermal cell
extracellular route
moves between the extracellular spaces does not enter the cells
xylem transports
solution of vitamin and water
transpiration (Def)
loss of water through evaporation, especially through the stoma
cohesion
the sticking of the same molecules due to attraction.
adhesion
the stickling of different molecules
what do guard cells control?
stoma opening and transpiration (evaporation)
sugar sink Def
is an organ that is a consumer or storage of sugar
water and minerals from
ROOTS to leaves
