BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Photoperiodism is the response to changes in daylength that enables plants to adapt to seasonal changes in their environment. The best studied example of photoperiodism in plants is flowering, but other responses to daylength include bud dormancy and bulb or tuber initiation.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Short-day plants control their flowering by blooming when days are short. Long-day plants bloom when the nights are short and the days are long, usually in late spring and summer. During this time of year, the nights are short and the days last longer than 12 hours.

Detailed explanation-5: -They are classified under three groups according to the photoperiods: short-day plants, long-day plants, and day-neutral plants.
