Question

Is root pressure active or passive?

Answer 1

Root pressure :

1. Root pressure is a force or hydrostatic pressure generated in the roots that aids in the upward movement of fluids and other ions from the soil into the vascular tissue of the plant i.e., Xylem.
2. The process is touched off by bibulous pressure in the root's cells.
3. The (active) absorption of mineral ions from the soil into the root xylem is driven by root pressure, which requires metabolic energy.
4. The osmotic potential of the xylem solution declines when ions accumulate in the root xylem, causing passive osmosis absorption of water from the soil into the xylem.
5. The process of water absorption through the roots of plants that requires energy in the form of ATP is known as active absorption.
6. This ATP is created during the root respiration process. As a result, the right response is ‘active absorption’.
