oksian1 [2.3K]

Below is the response:

<h3>What does seed germination mean?</h3>

Germination is the first stage of a seed's development into a seedling. To germinate, seeds require the appropriate combination of temperature, oxygen, and water. In a state of suspended animation known as dormancy, seeds wait to germinate until the environment is favorable for their survival and growth.

The option missing in the query is:

Dry cotton wool

wet cotton wool

covered with water

The initial conditions needed for a seed to germinate are as follows:

warm temperatures are needed for effective enzyme operation.

water, where chemical reactions can occur.

oxygen, for breathing.

Observations:

Seeds planted here won't sprout because of the dry cotton wool. Since some of the prerequisites are not met, they won't exhibit any modifications. (Water isn't present.)

Seeds placed on wet cotton wool will germinate since all the circumstances are there for germinations to occur.
