Solution

1. The temperature is unchanged in boiled seeds flask, while increases in germinating seeds flask.

2. By increase in temperature we account that energy is being released.

3. This release in energy is due to respiration of germinating plants.

Q. Why is some KOH placed in a small test tube in the flask with germinating seeds in the experiment to demonstrate occurrence of respiration in germinating seeds?
(1) To provide oxygen required by the seeds for respiration.
(2) To absorb carbon dioxide and create partial vacuum in the flask.
(3) To absorb water from the seeds to make them dry.
(4) To make the air present in the flask alkaline.
