Structure and Function of Plants Chapter 10C Plant Responses

The growth responses of a plant to its environment Tropisms The growth responses of a plant to its environment

Tropisms Positive tropism Negative tropism Phototropism Thigmotropism Gravitropism

Nastic Movements Reversible, repeatable plant movements Some triggered by touch Some triggered by light Other factors

A plant’s response to the length of time it is exposed to light Photoperiodism A plant’s response to the length of time it is exposed to light

Photoperiodism Phytochromes Short-day plants Long-day plants Day-neutral plants
