evapo transpiration

Cards (6)

how does water move into the plant from the soil
down a water potential gradient from the soil
therefore lots of mineral ions are needed in the root to maintain this gradient
what is the apoplastic route
in cell wall / between cell walls
what is the symplastic route
via the cytoplasm
which route offers the least resistance
the apoplastic route
water takes the path of least resistance
how do you force water into the xylem
by blocking the apoplastic route therefore forcing the water into the cell and then into the xylem
what blocks the apoplastic route
the casparian strip
made up of suberin
