प्रश्न
The given fig. refers to an apparatus which is used to demonstrate a physiological process:
(a) What is the purpose of keeping potassium hydroxide solution in test tubes X and Y?
(b) What is the purpose of keeping boiled peas soaked in disinfectant in test tube Y?
(c) Why has coloured water risen in tube 1?
(d) Name the biological process which causes the above rise.
(e) Define the biological process shown in the experiment.

उत्तर
(a) To absorb carbon dioxide produced during respiration
(b) If these are not soaked in disinfectant, the bacterial growth may be there in the tube Y and the accurate results may not be obtained due to bacterial respiration.
(c) The germinating peas respire and oxygen is used which creates a vacuum in the tube. So coloured water has risen in tube1.
(d) Respiration
(e) It is defined as the stepwise oxidation of glucose in the living cells to release energy.
