HII DEAR !!
@ASCENT OF SAP :--
⭐the upward moment of water from the root to aerial parts of the plant body is called ascent of sap or often called translocation of water .It is fascinating to understand how water moves in plants to such great heights ,such as 400 ft .
@MECHANISM OF TRANSLOCATION IN PLANT :--
⭐transpiration pull and cohesion theory⭐ :--
=====================================
●the theory was proposed by Dixon and jolly (1894) This theory based on :--
1. cohesive and adhesive properties of water.
2. Transpiration pull force developed in leaves by transpiration.
●cohesion is the phenomenon of attraction between similar molecules .the water molecules and the inner wall of xylem by adhesive property.
●there is attraction between water molecules and the inner wall of xylem by adhesive property.
●due to this water forms a continuous column in xylem vessel.
_____________
♦water is mainly absorbed by root hairs.
♦As xylem elements are present all over the length that's why xylem is mainly responsible for ascent of sap.
