Question

Before setting up an experiment to show that seeds release carbon dioxide during respiration, the seeds should be:
(1) dried completely
(2) boiled to make them soft
(3) soaked in potassium hydroxide solution
(4) kept moist till they germinate

Answer 1

In the above mentioned experiment, the seeds need to be kept moist till they germinate. If the seeds are not kept moist, they would dehydrate and eventually die.

Hence, the correct answer is option 4.
