Detailed explanation-1: -They are: Phototropism, Gravitropism, Chemotropism, Thigmotropism, Thermotropism and Hydrotropism.
Detailed explanation-2: -Tropisms are growth toward or away from a stimulus. Types of tropisms include gravitropism (gravity), phototropism (light), and thigmotropism (touch).
Detailed explanation-3: -Tropisms describe the growth or turning movement of an plant in response to a directional external stimulus. Phototropism is a growth movement in response to a unidirectional light source. Geotropism (or gravitropism) is a growth movement in response to gravitational forces.
Detailed explanation-4: -Phototropism. Plant hormones direct plant body development in response to a stimulus, like light. Thigmotropism. Gravitropism. Hydrotropism. 28-Feb-2018
