Question 1 Report

In H, the cotyledons are carried above the soil because

Answer Details
The cotyledons in H are carried above the soil because the hypocotyl grows faster than the epicotyl. The hypocotyl is the embryonic stem of the plant and is responsible for pushing the cotyledons out of the soil. As it grows, it elongates and lifts the cotyledons, exposing them to light for photosynthesis. This process is known as hypocotyl elongation, and it allows the plant to establish itself and start growing towards maturity.
