It seems like you're asking for examples of plants that use their stems as tendrils. There are many plants that exhibit this behavior, but here are three good examples:

1. Vines: Many vine species, such as grape vines, passionflowers, and morning glories, use modified stems that act as tendrils to climb. These tendrils wrap around supports and help the plant reach for sunlight.

2. Pea Plants: Pea plants are a classic example of stem-tendril plants. Their tendrils are actually modified leaves that coil around structures for support.

3. Cucumbers: Cucumber plants also develop tendrils from their stems. These tendrils help the plant climb upwards and spread across trellises or other structures.

While these are just a few examples, remember that there are many other plants that utilize stem-tendrils for support and climbing.
