Arrange the following in the correct order:
I. Hypocotyl elongates
II. Epicotyl elongates
III. Seed coat bursts
IV. Hypocotyl forms loop above the soil
V. Radicle grows downward
The correct option is D. III, I, V, IV, II
Seed germination:
The process of dormant embryo inside the seed developing into a new plant is called seed germination.
The order in which the seed germinates is as follows:
At first the seed coat bursts, the hypocotyl (stem of the germinating seedling, within the embryo just above the root) elongates.
The radicle grows downward as root, hypocotyl forms loop above the soil and grows as a future shoot and the epicotyl elongates.
Epicotyl is the region just above the first leaves of the developing plant. It is a very important region as it continues to grow as the plumule.
