Answer:
Photoperiod signifies towards the time that an animal or a plant gets exposed to light in a twenty-four-hour duration. Different types of plants need different durations of light exposure to follow their respective life cycles.
On the basis of getting exposed to light differently, the plants are differentiated into short-day plants, long-day plants, day-neutral plants, and intermediate-day plants. The day-neutral plants will undergo flowering at any length of the day, given that there is the availability of minimum amount of light, which is essential for usual growth. For example, beans, tropical plants, cotton, and others.
On the other hand, the intermediate-day plants will not flower if the days are too long or too short, like different varieties of grasses.
