Question

Given reason aseed kept in dark does not germination

Answer 1

For germination of seed sunlight is required but in the dark there is no sunlight so a seed kept in dark does not germinate.

Answer 2

For germination of seed daylight is required however oblivious there is no daylight so a seed kept in dull does not grow.

Beyond any doubt it will be powerful.

In this way, a seed on the dirt surface gets enough light to keep the dull type of phytochrome low for adequate time to forestall germination commencement.
