Statement A: Transpiration creates pressure in xylem sufficient enough to transport water up to 130 m high. Statement B: Transpiration creates a pushing force.

Statement A: Transpiration creates pressure in xylem sufficient enough to transport water up to 130 m high. Statement B: Transpiration creates a pushing force. Correct Answer Statement A is true but Statement B is false

Transpiration is the loss of water in the gaseous phase from the leaves. It is a necessary evil. It might be a major cause of loss of water but it is the driving force for ascent of xylem sap, therefore, conduction of water and minerals. It creates pressure in xylem which can allow water conduction up to 130m height. Transpiration is a pulling force while root pressure is a pushing force.
