What you’ll learn

Inside a SeedIdentify the parts inside a seed: the coat, baby plant, and food store.Almost every plant begins as a seed. Inside a seed is a tough coat that protects it, a tiny baby plant, and a store of food that feeds the baby plant until it can make its own.
A Seed Wakes UpUnderstand that seeds need water and warmth (not light) to germinate.A seed sprouts when it gets water and warmth. This is called germination. A seed does not need sunlight to start, because it begins growing under the soil in the dark. The root grows down and the shoot grows up.
Growing into a PlantDescribe how a seed grows into a plant and makes new seeds.The root grows first to drink water, then a shoot reaches up toward the light. Once the leaves open, the plant needs sunlight to make its own food. A grown plant makes flowers, and the flowers make new seeds, so the cycle continues.
