What Do Plant Parts like Roots and Leaves Do to Keep Plants Healthy?
This section explores how different parts of a plant, such as roots and leaves, help it grow, stay healthy, and survive in various environments. Each part has a unique and essential function.
Important Functions of Plant Parts
- Roots:
- Absorb Water and Nutrients: Roots take in water and minerals from the soil, which are essential for plant growth.
- Anchor the Plant: Roots hold the plant firmly in the ground, preventing it from falling over.
- Store Food: In some plants like carrots and beets, roots store extra food for later use.
- Leaves:
- Photosynthesis: Leaves use sunlight, carbon dioxide, and water to make food for the plant through photosynthesis.
- Gas Exchange: Tiny openings called stomata on leaves allow gases like oxygen and carbon dioxide to move in and out.
- Release Excess Water: Through a process called transpiration, leaves help release extra water to keep the plant cool and hydrated.
- Stems (Bonus Insight):
- Transport System: Stems carry water and food between roots and leaves.
- Support: Stems keep the plant upright and expose leaves to sunlight.
