Explanation:
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.
One is optamistic feedback and another is pesimistic.
