Question

The given diagram shows different stages of seed germination. Identify A, B, C and D and select the correct option.

• A. A-Plumule, B-Cotyledons, C-Epicotyl, D-Hypocotyl
• B. A-Radicle, B-Cotyledons, C-Epicotyl, D-Hypocotyl
• C. A-Mesocotyl, B-Cotyledons, C-Epicotyl, D-Hypocotyl
• D. A-Root hair, B-Cotyledons C-Hypocotyl, D-Epicotyl

Answer 1

The correct option is B A-Radicle, B-Cotyledons, C-Epicotyl, D-Hypocotyl

• The seed coat (testa) ruptures and the embryonic root (radicle) grows into the ground to extract nutrients and minerals. The cotyledon emerges out and leaves grow. As the plant grows, the embryonic stem is called hypocotyl and embryonic shoot is called epicotyl.
• Thus, the correct answer is 'A-Radicle, B-Cotyledons, C-Epicotyl, D-Hypocotyl.'
