TERM 1
leaves in wet v. arid
DEFINITION 1
in wet environments leaves big, in arid environments less
water so leaves small. land plants compromise between
maximizing photosynthesis and minimizing water loss
TERM 2
active transport part 1
DEFINITION 2
diffusion across a membrane is passive, while the pumping of
solutes across a membrane is active and requires energy
(ATP)ex: the uptake of mineral ions into to root hair cells in
plants
TERM 3
active transport part 2
DEFINITION 3
primary active transport involves use of energy
ATP.Secondary active transport requires the use of
electrochemical gradient.
TERM 4
transport proteins
DEFINITION 4
most solutes pass through transport proteins embedded in
the cell membrane (this can be active or passive)
TERM 5
apoplast
DEFINITION 5
through cell wall
