Question

WHAT IS ASCENT OF SAP? EXPLAIN VARIOUS FORCES RESPONSIBLE FOR THE RISE OF CELL SAP.

Answer 1

Answer:

• it is an upward movement of water and minerals in xylem tissue of a plant

Explanation:

• Ascent of SAP -  So it is and upward movement of minerals and  water in xylem tissue of a plant from roots to different part of the plant.

• the forces responsible for the rise of cell sap

1. Root pressure is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the day.
2. Capillarity  - the ability of water to rise in thin tubes

Answer 2

ascent or SAP is a mixture of water and mineral which is carried by xylem from the root to the leaves in order to manufacture food.

this movement is against the gravity so only osmosis process cannot help it that is why turgor pressure or suction force is created by leaves during transpiration and due to this the SAP is transported vertically upward.

I hope my answer will help you.
