How plants tell time - Dasha Savage?

Plants use special clocks inside them to know when it’s time to grow or rest, just like you know when it's time for breakfast or bedtime.

Imagine your body is like a clock that ticks every day. Plants have their own kind of body clock, called a biological clock. It helps them know when it's light outside and when it's dark, without needing to look at the sun!

Inside plants, there are tiny parts called cells, like little rooms in a house. These cells have special chemicals that change during the day and night. When it gets dark, these chemicals tell the plant: “It’s time to rest.” When it gets light again, they say: “Time to wake up and grow!”

This is kind of like having an alarm clock in your head, but for plants! Some plants even bloom at certain times because of this clock, just like how you might feel sleepy after a long day.
