Question

Choose the correct answer from the alternatives given.
Seedlings grown in darkness:

• A. are smaller than those grown in light
• B. are taller than those grown in light
• C. are of the same size
• D. none of the above

Answer 1

The correct option is B are taller than those grown in light

seed on the soil surface gets enough light to keep the dark form of phytochrome low for sufficient time to prevent germination initiation. It is only when the seed is in permanent darkness that the dark form of phytochrome is active for long enough to trigger germination.

So, the correct option is 'are taller than those grown in light'.
