Detailed explanation-1: -Photoperiodism is the phenomenon in which various physiological reactions like the flowering response to the relative length of day and night or dark or light periods. Short day plants are those plants that begin flowering when the days are shorter than their critical day length.

Detailed explanation-2: -Plants can differentiate and develop in response to light (known as photomorphogenesis), which allows plants to optimize their use of light and space. Plants use light to track time, which is known as photoperiodism. They can tell the time of day and time of year by sensing and using various wavelengths of sunlight.

Detailed explanation-3: -Photoperiodism is the physiological reaction of organisms to the length of night or a dark period. It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods.

Detailed explanation-4: -The relative length of day and night is known as photoperiod. Some plants need to be exposed to sunlight for a particular duration of time to induce flowering. This is the reason behind the seasonal blooming of flowers.
