Detailed explanation-1: -Response of a plant to the changing relative length of the day and night is called phototropism .

Detailed explanation-2: -“Photoperiodism” is defined as “The response to changes in daylength that enables plants (or any other living organisms) to adapt to seasonal changes in their environment.”

Detailed explanation-3: -Photoperiodism is the regulation of physiology or development in response to day length. Photoperiodism allows some plant species to flower-switch to reproductive mode-only at certain times of the year.

Detailed explanation-4: -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-5: -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. Light can also elicit a directional response in plants that allows them to grow toward, or even away from, light; this is known as phototropism.
