How Does a Plant Know When to Bloom?

Plants have a special kind of clock inside them that helps them know when to bloom. It’s like they’re watching the days get longer or shorter, and when they notice enough change, they start blooming! Think of it like this: if you count how many days pass between sunrise and sunset, and then wait for the right number, you’ll know when it's time to grow flowers.
