Question

Which of the following statements about the hypocotyl hook is not true?

Options

• It develops below the attachment of the cotyledons.

• It is the first structure to emerge from a dicot seed.

• It precedes the cotyledons and shoot apex up through the soil.

• It straightens when exposed to light.

Answer 1

It is the first structure to emerge from a dicot seed.

Explanation:

This is not true because the hypocotyl hook develops below the cotyledons and emerges after the radicle, not as the first structure. It helps in pushing the shoot apex and cotyledons above the soil during germination by forming a protective hook that straightens when exposed to light.
