Imagine a plant that wakes up every morning and checks the length of the day. If it's long enough, it knows it's time to flower! This is called photoperiodism, when plants use light to know when to bloom. Some plants wait for longer days (like in spring), while others bloom after shorter days (like in autumn). It’s like a natural timer that tells the plant exactly when to start growing flowers.
Examples
- A dandelion waits until spring to bloom when days get longer.
- A chrysanthemum flower opens in the fall after the days become shorter.
- A tomato plant starts producing flowers after it senses the change from summer to autumn.
