TED-ED: How plants tell time - Dasha Savage

The video explores how plants and other organisms sense time through circadian rhythms. It begins with Linnaeus's concept of a flower clock, highlighting how plants like morning glories and moon flowers bloom at specific times. The video explains circadian rhythms as internal clocks that help organisms adapt to environmental changes. In plants, phytochromes detect light and temperature, triggering molecular reactions for photosynthesis and growth. These rhythms also guide daily and seasonal activities, allowing plants to adapt to their environment and maintain their schedules.
