Explain why it was important to keep on set of seedling in the light

It was important to keep on set of seedling in the light because seedlings will become fragile and thin and would not produce the healthy stem if no sun light is provided to the seedling.

Explanation:

Seedlings have three parts called hypocotyl, cotyledons and radicle.

The radicle is the downward part responsible for making root system of the plant.

When root is formed and anchored to the ground a shoot emerges from hypocotyl.

The growth of plants depends on the temperature requirement by seedling.

The seedling has to start photosynthesis for growing demands of nutrients of growing plant. The photosynthesis requires sunlight so seedling are always kept in sunlight for the growth and height of the plant.

Temperature and light intensity is a determining factor in the growth seedling and eventually plants.

A photoperiod ( length of light period required by a plant for growth and reproduction)  which is less than 14 hours causes stunting in plants.
