Question

Which process acts as suction to pull water from xylem cells of roots. Explain it

Answer 1

Transpiration: Transpiration is the technical term for the evaporation of water from plants. As water evaporates through the stomata in the leaves (or any part of the plant exposed to air), it creates a negative pressure (also called tension or suction) in the leaves and tissues of the xylem.

The negative pressure exerts a pulling force on the water in the plant’s xylem and draws the water upward (just like you draw water upward when you suck on a straw).

Answer 2

Answer:

Answer:Water moves by osmosis from the soil solution into the root hair cells down a water potential gradient either along the symplastic patway or the apoplastic pathway. >Water is drawn into the endodermis cells. ... creates tension that draws water along the cell walls of the cells of the root cortex.
