Question

What is ascent of sap?

Hint:

Transpiration and root pressure work together to drive the ascent of sap, ensuring plants get the necessary water and nutrients.

Answer 1

The ascent of sap refers to the upward movement of water and minerals from the roots to the leaves through the xylem vessels. This process occurs due to the combination of transpiration pull, which is caused by the evaporation of water from the stomata in leaves, and root pressure, which is generated by the active uptake of water by the roots. The ascent of sap is essential for maintaining hydration and transporting essential nutrients in plants.
