Plants have a special kind of timer inside them that helps them know when to grow. It’s like they’re waiting for the right signal, such as longer days or warmer temperatures, before they start growing again in spring. This secret timer is called a biological clock, and it works all year round, even when we can’t see it.
How It Works
Plants use two main clues: light and temperature. In winter, the days are short, so plants stay asleep. When the days get longer in spring, they know it’s time to wake up. Some plants also wait for warmer temperatures before starting to grow.
Examples
- When the days get longer, like in spring, plants start growing again.
- A tree stays asleep during winter, but when it gets warmer, it wakes up and grows new leaves.
- Some flowers wait for cold temperatures, like in winter, before they bloom in spring.
