Question

Which of the following statements are true concerning stem modifications in plants?
I. Some underground stems are modified to store food as seen in ginger.
II. Stem tendrils develop from axillary buds in plants like cucumber and they help in climbing.

• A. Only I is correct
• B. Only II is correct
• C. Both I and II are correct
• D. Both I and II are incorrect

Answer 1

The correct option is C Both I and II are correct

Rhizomes are modifications of stem where they are seen storing food. They are non-green and take part in perennation. They have buds to form new aerial shoots during favorable conditions, e.g., ginger and turmeric, etc.

Stem tendrils of cucumber are modified aerial stems which develop from auxillary buds. They are thread-like sensitive structures that can coil around the primary support and help the plant in climbing. Hence, both the given statements are correct.
