Write contrasts and comparisons of the style of response in plants and animals to
the stimuli.
A. 1) Both plants and animals react to various stimuli around them. But the method of responding to stimuli is not similar in plants and animals.
2) Higher animals respond to stimuli because they have a nervous system and an endocrine system.
3) Plant do not have a well defined nervous or endocrine system. They do have some mechanism of control by means of some chemicals or hormones.
4) Plants can sense the presence of stimuli like light, heat, water, touch, pressure, . chemicals, gravity, etc.
5) The hormones present in the plants called phytohormones control response to¬wards the stimuli. Phytohormones coordinate the activities of the plant usually by controlling one or the other aspect of the growth of the plant.
