How does capillarity helps in rise of water in xylem?
Asked by Topperlearning User | 04 Jun, 2014, 01:23: PM
Expert Answer
Narrower the diameter of a tube, greater will be the height of water rising in it exerting a force called capillary force and this phenomenon is called ‘capillarity’. Xylem vessels are very narrow. Narrow diameter of xylem vessels causes the water to rise from a lower level to fill up the vacuum created by the loss of water due to transpiration from leaves.
