Solution
The correct option is D kept moist till they germinate
The correct option is D.
Explanation of the correct option:
- Germination of seeds involves aerobic respiration.
- Aerobic respiration takes place when oxygen is available.
- During aerobic respiration, seeds require oxygen as well as water and, in turn, produce carbon dioxide.
- Keeping seeds moist till germination will provide them with the required water content, which is necessary for the process of aerobic respiration and, in turn, causes the growth of the seed.
Explanation of the incorrect options:
Option A:
- Dried seeds will not be able to germinate as they cannot carry out the process of respiration.
Option B:
- The boiling of seeds kills them as the rise in temperature inside the seed dries out all the moisture.
Option C:
- KOH solution absorbs carbon dioxide released during the process of respiration in germinating seeds.
Therefore, the seeds should be kept moist till they germinate before setting up the experiment to demonstrate the release of carbon dioxide from seeds during respiration.
