Phototropism vs Photoperiodism
Similarities and Differences between Phototropism and Photoperiodism in Plants
Phototropism: Phototropism is the growth or movement of plants (or any organism) in response to light. Phototropism can be of two different types – (1) Positive Phototropism – movement towards the source of light, (2) Negative phototropism – movement away from the light. Negative phototropism is also called as Skototropism.
Photoperiodism: Photoperiodism is the response of plants (or any organism) to the lengths of dark and light periods in a day. The changes in the duration of light and dark periods in a day are called photoperiods. In plants, the photoperiodism induces flowering.
