2.80 understand that plants respond to stimuli
Plants respond to stimuli. They will react to changes in the environment, like temperature and light, as they have receptors which can detect a change and effectors to carry out the response. Usually the response is plant hormones- commonly auxin- which stimulate plant growth, stimuli for this are often light (photo-tropism), water (hydro-tropism) or gravity (geo-tropism).
