In cucurbita growth of the tendril towards support is due toa)effect of gravityb)effect of lightc)rapid cell division in tendril cells which are in contact with supportd)rapid cell division in tendril cells which are away from the supportCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

Auxin is responsible for growth and it prefer to be away form support . so it collects on the side away form support . It promote rapid cell division on that side . due to this it grows more than the side near form support .
so d is correct

Answer

The answer is (d) Rapid Cell Divisions in Tendrills cells in contact with the Support.

Tenderils are defined as soft succular stems, leaves or petiole. Tendrils have hook shaped structure and move in a circular fashion and cover like a helix.. Their main function is to provide support to plants and prevent drooping of pods which may hamper further growth and development.

Answer

Your ans. will option (D) coz tendrils are basically stems, leaves or petoile in a circular, hook-like formation with the primary function if supporting the plant. They are usually formed when some object is obstructing the growth of the plant.

Answer

Explanation:
Cucurbita is a genus of flowering plants in the gourd family, Cucurbitaceae, commonly known as pumpkins, squash, and gourds. The tendrils of cucurbita are modified shoots that arise from the axils of the leaves and help the plant in climbing over the support. Tendrils are thin, wiry, and coiled structures that grow towards the support. The growth of the tendril towards support is due to rapid cell division in tendril cells which are away from the support.

Rapid Cell Division in Tendril Cells:
The tendril cells away from the support divide much more rapidly than the cells in contact with the support. The cells away from the support elongate and push the tendril towards the support. The cells in contact with the support do not divide and remain small in size. This results in the tendril coiling around the support and providing the plant with support for climbing.

Effect of Gravity and Light:
Gravity and light do not have a direct effect on the growth of the tendril towards the support. The tendril grows towards the support due to the differential growth of the cells away from the support. However, the orientation of the tendril towards the support is influenced by the orientation of the plant with respect to gravity and the direction of light. The tendril grows towards the support in a way that minimizes its exposure to light and maximizes its contact with the support.

Conclusion:
In conclusion, the growth of the tendril towards the support in cucurbita is due to rapid cell division in tendril cells away from the support. This differential growth of the cells results in the tendril coiling around the support and providing the plant with support for climbing. The orientation of the tendril towards the support is influenced by the orientation of the plant with respect to gravity and the direction of light.
