The chemical process the question refers to is photosynthesis
Explanation:
Starting off, the conditions required for a seed to germinate are:
- warm temperatures, so that enzymes can act efficiently.
- water, for chemical reactions to place.
- oxygen, for respiration.
<u>Observations</u>:
Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)
Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.
Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.
