Positive chemotaxis is movement toward the source of the chemical stimulus (along the chemical concentration gradient in air or water); negative chemotaxis is movement away from the source. The phenomenon is known to exist in a number of microorganisms and invertebrates.
Redvine (Brunnichia ovata) tendrils coil upon contact. Thigmotropism is a directional growth movement of curvature which occurs in response to stimulus of contact. Thigmotropism is found in twining plants and tendrils. After initial contact with support due to nutation, the tendril or twiner shows less growth in the region of contact and more growth on the opposite side. As a result, they bend around the support.
