Question

The terms active water absorption and passive water absorption were given by

• A. Renner
• B. Atkins
• C. Priestley
• D. Kramer

Answer 1

The correct option is D Kramer

Kramer proposed that water is absorbed by two mechanisms:

1. Active absorption

2. Passive absorption

Passive absorption is the absorption which takes place without the expenditure of energy. The water molecules move from higher concentration to the lower concentration which is towards the gradient.

Active transport is the transport where the direct expenditure of energy takes place and the water molecules move against the gradient which is from lower concentration to the higher concentration.

So, the correct answer is option D.
