Biology Notes: Plant Transport Systems and Water Movement, Quizzes of Biology

Definitions and terms related to plant transport systems and water movement. Topics include the role of leaves in wet and arid environments, active transport of solutes, transport proteins, apoplast and symplast, bulk flow, and translocation of sugars in the phloem.

What you will learn

  • What is the difference between passive and active transport of solutes across a membrane?
  • What is the role of active transport in moving sugars in plants?
  • How do land plants balance maximizing photosynthesis and minimizing water loss?

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

leaves in wet v. arid

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

symplast

through cytoplasm

TERM 7

bulk flow

DEFINITION 7

movement of fluid driven by pressure

TERM 8

active transport used

to?

DEFINITION 8

to move sugars; proton pumping and co-transport of sucrose

with H+ enables the phloem to accumulate sucrose.sugars

diffuse from the phloem to the sink

TERM 9

aquaporins

DEFINITION 9

are transport proteins in the cell membrane that allow the

passage of water

TERM 10

endodermis

DEFINITION 10

is the innermost layer of cells in the root cortex and a

checkpoint for selective passage of solutes
