Answer 1

Answer:

C. Thigmotropism

Explanation:

Thigmotropism is the turning or bending of a plant or other organism in response to a touch stimulus. Answer choice A can be eliminated because its root "hydro" can give us a hint that it is related to water. Answer choice B implies that it will have something to do with gravity, due to the root "geo." Answer choice D can be eliminated because its root "photo" tells us it will be involved with light.

Answer 2

Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow. Plant responses are controlled by hormones. Some plant responses are tropisms. Plants also respond to daily and seasonal cycles and to disease.
