halophyte
halophyteA vine grows round and round the trunk of a tree. A seed in the dark ground begins to grow toward the surface. Although plants lack a nervous system, they do sense and respond to signals from their environment.

They respond to such stimuli as light, temperature, gravity, and touch. Most plant responses are slow—so slow that you can't see the response occurring. In a few plant species, however, the response is very rapid indeed.

After time, the leaves return to their normal position. This response is an example of a rapid plant movement. Touch triggers responses that cause cells at the base of each leaflet to lose ions. Due to osmosis, water follows the ions out of the cells. The cells shrink, causing the leaflet to droop.
Some scientists hypothesize that leaf folding in a heavy wind is an adaptation that reduces surface area and saves water. Another hypothesis states that the folding response makes the plant less attractive to animals trying to eat the plant. The rapid movement may serve to bump off (or scare off) an insect, for example.

Tropisms are typically regulated by plant hormones, especially auxins. Unlike rapid plant movements, tropisms are not rapidly reversible.

Most climbing plants have tendrils that respond by coiling and grasping when they touch rigid objects. Thigmotropism enables climbing plants to use objects for support while growing toward sunlight.
