Question

Active absorption is affected by:

• A. Osmotic concentration
• B. Associate tissue structures
• C. Transpiration
• D. Sucking capacity of root hair

Answer 1

The correct option is A Osmotic concentration

Active absorption refers to absorption against the concentration gradient. Absorption of a solute from a region of low concentration to a region of higher concentration with the help of energy, is called active absorption. Hence, active absorption depends on osmotic concentration.

So, the correct answer is 'Osmotic concentration'
