The term CLINGING PART OF A PLANT can be summarized as a TENDRIL, which is a seven-letter word. Tendrils are thin, curling structures that grow from the stems of certain plants and help them to climb and attach to other surfaces. They are typically found on climbing plants such as vines, but can also be seen on some non-climbing plants. Tendrils are usually flexible and can wrap around objects to provide support for the plant.
