Practice MCQ for SSC, UPSC, RRB Exams

B. Transpiration is zero B.
C. Soil is dry C.
D. Leaves are removed D.

Correct Answer: B সঠিক উত্তর: B

Explanation ব্যাখ্যা

Root pressure is the force exerted by the roots to push water and nutrients upward through the plant, and it's most active when the plant is absorbing more water than it is losing through transpiration. When transpiration is low, the roots have more opportunity to build up pressure by actively absorbing water from the soil, leading to a high root pressure.
