Question

Investigate the conditions required for seed to germinate. keep the dishes at room temperature for a week.explain your observations
Dry cotton wool
wet cotton wool
covered with water

Answer 1

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.

Observations:

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.
