Question

During seed germination, seed coat ruptures due to

• A. Massive imbibition of water
• B. Sudden increase in cell division
• C. Differentiation of cotyledons
• D. Massive glycolysis in endosperm and cotyledons

Answer 1

The correct option is A Massive imbibition of water

Seed germination is the growth of an embryo of the mature seed into a seedling or new plant by breaking the hard seed coat. It involves the following events:
●Uptake of large amounts of water by dry dormant seed due to imbibition.
●Swelling of the seed results in the rupturing of the seed coat.
●Elongation of the embryonal axis by the influence of favourable conditions like water, oxygen , light and temperature.


Final answer : (C) Massive imbibition of water
