Rise in the water level from X to Y in the given experimental set-up demonstrates

A

aerobic respiration

B

anaerobic respiration

C

photosynthesis

D

transpiration pull

Text Solution

Verified by Experts

The correct Answer is:
A
Oxygen required for aerobic respiration is taken up from the air of the apparatus. Carbon dioxide released during aerobic respiration is absorbed by potassium hydroxide (KOH). Therefore, a partial vacuum us created in the conical flask. This causes the rise of water in the bent tube. That oxygen is consumed during aerobic respiration can be tested by taking a burning splinter into the conical flask, which gets extinguished.
