Q

Root pressure

A

As Water moves up the root by osmosis it builds up a pressure that pushes water up the water into the xylem

Q

Transpiration > Upward movement of a plant

A

As the water evaporates from the leaf by transpiration more water is pulled upwards though the xylem into the leaf

Q

Role of transpiration

A

Water evaporates from leaf cells

This creates an osmotic gradient

The leaf cells become less turgid

Causing water to move out of the xylem to the leaf cells
