Thick and woody twiners/climbers are known as "lianas." Lianas are a type of plant that have thick, woody stems and climb or twine around trees or other supports in order to reach sunlight and access resources. They are commonly found in tropical and subtropical regions, where they play a significant role in forest ecosystems.
Lianas have adaptations that allow them to climb and compete for light and space in dense forest environments. Their thick, woody stems provide support and strength as they climb up trees, and they often have specialized structures such as tendrils or hooks that help them attach to their supports. Lianas can grow to impressive lengths and can form tangled networks in forest canopies.
These climbing plants are different from other types of climbers, such as vines, as they typically have thicker and more rigid stems. This woody nature gives them the ability to support their own weight and persist for longer periods, even in mature forest ecosystems. Hence, the correct answer is option 2.
