- 5What Plants Need to GrowPlants need sunlight, water, carbon dioxide, and nutrients from soil to grow. Their roots absorb water and minerals while their leaves capture sunlight for photosynthesis.Experiment
- 6How Seeds GerminateSeeds contain a tiny plant embryo and a food supply. When conditions are right—enough water, warmth, and oxygen—the seed germinates and a new plant begins to grow.Experiment
