Unit V - Plants Anatomy and Physiology
Plant growth regulator: a chemical produced by plant cells that regulates growth and differentiation
Plants can modify their growth and differentiation through plant growth regulator
act by signaling plant cells to undergo particular changes
auxins, gibberellins, cytokinin, ethylene, and abscisic acid
Tropism: a directional change in growth/ movement in response to a stimulus
Phototropism: a change in direction of a growing plant in response to light
Gravitropism: a directional change in growth pattern in response to gravity
Thigmotropism: a directional change in growth pattern in response to touch
