Tendrils are the thin thread-like groups on the stem or leaves of climbing plants. These are sensitive to touch of other parts objects (i.e. thigmotropic). When a tendril touches an object, then the site in contact with object grows slowly than its other side, (i.e. rapid cell divisions in cells that are away from the support). This causes the tendril to bend towards the object by growing towards it, wind around object and cling to it.

Explanation:
The growth of tendrils in pea plants is primarily due to rapid cell divisions in the tendrillar cells that are away from the support. This process allows the tendrils to elongate and reach out for support, enabling the plant to climb and attach itself to nearby structures.
Factors affecting tendril growth:
1. Effect of light: Light is an important factor that influences the growth of tendrils. Tendrils tend to grow towards a light source, a phenomenon known as phototropism. The presence of light stimulates the growth of cells on the shaded side of the tendril, causing it to curve towards the light source.
2. Effect of gravity: Gravity also plays a role in tendril growth. Tendrils exhibit positive gravitropism, meaning they grow in the direction of gravitational pull. This helps the tendrils to orient themselves in a way that allows them to reach a support structure.
3. Rapid cell divisions: The main reason for the growth of tendrils is rapid cell divisions in the tendrillar cells that are away from the support. These cells undergo active cell division, resulting in the elongation of the tendril. As the cells divide and elongate, the tendril extends and reaches out for support.
4. Contact with support: Once the tendril comes into contact with a support structure, the cells in contact with the support stop dividing. However, the cells away from the support continue to divide rapidly, causing the tendril to coil around the support and firmly attach itself.
Conclusion:
In conclusion, the growth of tendrils in pea plants is primarily due to rapid cell divisions in the tendrillar cells that are away from the support. This process allows the tendrils to elongate and reach out for support, enabling the plant to climb and attach itself to nearby structures.
