Biology Question on respiration in plants
Potometer works on the principle of :
A
amount of water absorbed equals the amount transpired
B
osmotic pressure
C
root pressure
D
potential difference between the tip of the tube and that of the plant
Answer
amount of water absorbed equals the amount transpired
Explanation
Solution
A potometer is an instrument used to measure the rate of transpiration in plants. It does so by allowing water to be taken up by the plant while simultaneously measuring the amount of water lost through transpiration. This principle helps in determining the rate of water uptake and transpiration in the plant.
So, the correct option is (A): amount of water absorbed equals the amount transpired
