Modified Structures - 1 We observed earlier several types of specialized roots. There are also a number of stem, leaf and shoot specializations beyond the leaf modifications discussed previously for different habitats. Some of these are discussed below.

Vines often have aerial roots to cling to their "host" structure, or, alternatively, have twining stems to wrap around the host structure, or tendrils to wrap around the host structure. Lianas are woody vines.

Unformatted text preview: Some examples of vines are: • English Ivy • Boston Ivy • Virginia Creeper • Tropical lianas • Common bindweed Clinging roots of Vines and Lianas Tendrils Tendrils can be modified stems or leaves that are used to cling by coiling around the support structure. Most tendrils are pressure sensitive and show differential growth of the cells of the tendril to achieve the coiling. The direction of the coiling is also regulated. Some examples of plants that have tendrils are: • Peas (modified leaves) • Grapes (modified stems) Pea tendrils Grape tendrils...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
