Wednesday: Why light matters

Rocket peeks in the cupboard. "Can cup B grow in the dark?"

Raven asks, "What do you notice?"

Nova hints, "What is inside a seed?"

Food packed in the seed

A seed holds a tiny new plant.

It also holds a little food.

The tiny plant uses that food to start growing.

So a seed can start to grow in the dark.

Leaves need light

Seed food does not last forever.

Then the plant needs to make its own food.

Leaves use light to make food.

Without enough light, a plant cannot make enough food.
