Question

how does transportation of water occur at night in the absence of transpiration?

Answer 1

transpiration of water occur at night in the absence of transpiration because the loss of water occurs at night

Answer 2

Transportation of water occurs at night due to the presence of the root pressure.

• In the normal day time,when the transpiration happens in significant amount,the water transportation is an easy thing in the plants.

• But,in the night time when the transpiration is negligible, the root pressure takes the role of sending water and sap to the leaves of the plant.

• Root pressure is a transverse osmotic pressure which sends water and sap to the leaves of the plants, mainly through the xylem.
