Question

The phenomenon of absorption of water that depends on water loss from aerial parts of plants (Transpiration) is

• A. Active absorption
• B. Passive absorption
• C. Both passive and active absorption
• D. None of the above

Answer 1

The correct option is B Passive absorption

Passive absorption is defined as the absorption of water without the direct expenditure of metabolic energy. Transpiration, the evaporation of water, mainly, through stomata, results in creation of water gaps that are filled by passive absorption of water by the roots, also referred to as transpirational pull.

Thus, the correct answer is option (B).
