Daylength is a dependable predictor of the time of year, allowing developmental events to be planned to correspond with specific environmental conditions. As a result, the response to photoperiod has evolved.
A plant's ability to grow either toward or, in some situations, away from a light source is known as phototropism.
The modulation of physiology or development in relation to day length is known as photoperiodism.
An organism's functional or behavioral reaction to variations in the duration of daily, seasonal, or yearly cycles of light and darkness is called photoperiodism.
Although photoperiodic reactions can be adequately predicted, an organism's response can also vary depending on temperature, nutrition, and other external conditions.
