All of the following involves osmosis except
Water absorption by root
Stomatal movement
Swelling of wooden door during raining season
Turgor pressure in Mimosa
Importance of Osmosis -
1.Water absorption by roots
2.Stomatal movement
3.Turgor pressure in Mimosa and Desmodium
4.Drough and frost resistance
Movement of water in xylem occurs due to physical forces, like suction pull and surface tension as in case of capillary rise of liquid.
Therefore, the correct answer is option C.
