Plant biology on Khan Academy: Plants may seem less interactive than animals. But they actually have many ways of responding to their environment, changing their growth or physiology to make the best use of available resources. Learn more about plants and their response to environmental cues.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

What happens when the night time interrupt with light more than one time? I learned some interesting things in my school lessons and I came to listen to khan academy for a more accurate explanation but this video didn't include them.

[@eno3366]

studied this very recently, it actually depends on the last type of light that interrupts the night time. we already know that interruption in night time for short day plants prevent them from flowering but for long day plants, you can expose them to red and far red light more than once but the only condition required for it to flower is that the last light it's exposed to is red light.
