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.

We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
