Question

what is ascent 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.

Answer 2

Answer:Water enters a root hair → the cell content becomes dilute → cell next to the root hair cell will be more concentrated → Water enters by osmosis into this cell → Water, along with dissolved nutrients moves along from cell to cell and goes into the xylem.Thus root pressure is the force which pushes water into the xylem. This is also called ascent of sap.
