Explain capillarity theory of water translocation.

1.	Explain capillarity theory of water translocation.
Answer» 1. Capillarity theory of water translocation is proposed by Bohem. 2. Capillarity is because of surface tension and cohesive forces and adhesive forces of water molecules. 3. Xylem vessels and tracheids are tubular elements having their lumen. 4. In these elements water column exists due to combined action of cohesive and adhesive forces of water and lignified wall. 5. As a result of this capillarity water is raised upwards.
