Question

The growth of tendrils in pea plants is due to

• A. effect of light
• B. effect of gravity
• C. rapid cell divisions in tendrilled cells that are away from the support
• D. rapid cell divisions in tendrilled cells in contact with the support

Answer 1

The correct option is C

rapid cell divisions in tendrilled cells that are away from the support

The correct option is C.

Explanation for the correct option:

1. Tendrils are growths of some plants that resemble hair or extremely fine threads and are seen on the stems and leaves of plants known as climbing plants.
2. Rapid cell division in the tendril cells that are not attached to the support is what causes the tendril to expand in pea plants.
3. Vine and liana (climbing plants) employ tendrils, which are thin stem- or petiole-like structures, to wrap around or hook support.
4. Due to this requirement for support, anytime tendrils come into contact with or touch an item, the side they are touching grows slowly while the side they are touching opposite is shown to grow extremely quickly.
5. Cells on the opposing side rapidly divide as a result.
6. This aids in adhering and prevents the tendril from flowing with the wind, causing it to bend to the side where it meets the item.

Final answer: The growth of tendrils in pea plants is due to rapid cell divisions in tendrilled cells that are away from the support.
