Question

only 1/4 inch of soil is that the Seed packets give a recommended planting depth for the enclosed seeds. The most likely reason some seeds are to be covered with only 1/4 inch of soil is that
- the seeds require light to germinate.
- seedlings do not produce a hypocotyl.
- seeds require a higher temperature to germinate.
- seedlings do not have an etiolation response.

Answer 1

Answer:

The most likely reason some seeds are to be covered with only 1/4 inch of soil is that the seeds require light to germinate.

Explanation:

This seed packets does not say anyhing about temperature so we can rule out higher temperature. It is really rare to plant with seeds does not have any cotyledons and also we can't really know it from the question. Etiolation response can also be found in seedlings also from this question we can't know this for sure.

Only thing that is changes if you cover the seeds with only 1/4 inch of soil is light. If you completely cover this seed with soil it wouldn't grow.
