Imagine a seed like a sleepy baby, it needs the right signal to wake up and start growing. When the weather gets warm, or when it rains, the seed gets a message that says, 'It’s time!' The message comes from chemicals in the soil or water, which tell the seed to grow into a plant. Just like you might wake up because your alarm clock rings!
Examples
- A seed buried under snow waits until spring, when the sun warms it up enough to start growing.
- An acorn on the forest floor stays asleep until rain soaks it and sends a signal to grow.
- Seeds in a packet of soil stay still until you water them and say, 'Time to wake up!'
