Question

what is ascent of sap????

Answer 1

The ascent of sap in the xylem tissue of plants is the upward movement of water and minerals from the root to the crown. Xylem is a complex tissue consisting of living and non-living cells. The conducting cells in xylem are typically non-living and include, in various groups of plants, vessels members and tracheids.

Answer 2

Heya,

During transportation, evaporation of water molecules from leaf cells creats a suction force or pressure in photosynthetic cells that pulls water up the column from the xylem cells of roots. This force is known as transpiration pull and is responsible for the upward movement of sap(water + minerals) from roots to leaves. Thus, water lost through stomata is replaced by the water from the xylem vessels in the leaf. This is known as ascent of sap.

Hope this helps....:)
