INFOGRAPHIC 32.8 PLANTS SENSE AND RESPOND TO THEIR ENVIRONMENT
Plants can respond to a variety of stimuli, including light, touch, and gravity. Many of these responses are mediated by a plant hormone called auxin. Unequal distribution of auxin leads to a corresponding unequal pattern of cell elongation in stems and roots, and thus growth in a particular direction.
