What is the effect of photoperiod on flowering in plants? (2020)

Step 1: Understand what photoperiod means. Photoperiod is the length of time a plant is exposed to light in a day.
Step 2: Recognize that plants use light to know when to flower. They can sense the changes in day length.
Step 3: Identify the two main types of plants based on photoperiod: short-day plants and long-day plants.
Step 4: Short-day plants flower when the days are shorter (less light), usually in late summer or fall.
Step 5: Long-day plants flower when the days are longer (more light), typically in late spring or early summer.
Step 6: Understand that some plants are day-neutral and do not depend on photoperiod to flower.
Step 7: Conclude that photoperiod is important because it helps plants time their flowering for optimal reproduction.
