Question

Which of the following best describes the widely accepted root pressure theory in plants?

• A. It explains the mechanism of water movement through transpiration pull.
• B. It describes the active uptake of minerals from the soil.
• C. It refers to the pressure exerted by roots to push water upwards through the xylem.
• D. It relates to the diffusion of gases in plant cells.

Hint:

Root pressure is particularly important in small plants and during the early stages of plant growth, helping to maintain water flow in the absence of strong transpiration forces.
