Question

The germination of a seed is:

• A. a physical, reversible change in which energy is produced
• B. a fast, chemical reaction in which energy is released
• C. a slow, irreversible, desirable, chemical change
• D. a fast, irreversible, undesirable, chemical change

Answer 1

The correct option is C a slow, irreversible, desirable, chemical change

The germination of a seed is a slow and irreversible process as it takes few days to months to germinate a seedling from a seed, and this is irreversible because the same seedling which grows into a plant cannot revert back in its growth.
The growth of seedlings in a crop is a desirable change i.e the changes which are beneficial to nature or which does not cause any harm to nature.
And this is a chemical change as it involves many hormones and enzyme actions.
