Apoplast, Symplast & Vacuolar Pathways Flashcards
1
Q
What are the three pathways?
A
apoplast, symplast, and vacuolar pathways
2
Q
What is the apoplast pathway?
A
water and minerals e.g. mg, move through the cell walls
3
Q
What is the symplast pathway?
A
water moves across plasma membrane by osmosis
moves between cytoplasm of one cell to the next via plasmodesmata
4
Q
What is the vacuolar pathway?
A
water moves through the cytoplasm and vacuoles
5
Q
What is the caspian strip?
A
impermeable to water - forces water from apoplast pathway through the cell membrane
membrane repels charged particles
6
Q
Where is the casparian strip located?
A
in the endodermis after the cortex
