What your child will learn: Cells: The Building Blocks of Life
- All living things are made of cells: the smallest unit of life. Bacteria have one cell; you have trillions!
- Cell city parts: the nucleus is city hall (holds DNA instructions), mitochondria are power plants (make energy), the membrane is the city wall (controls what enters).
- Plant cells have extras: a stiff cell wall and chloroplasts, the green solar panels that make food.
- Cells team up: similar cells form tissues → tissues form organs → organs form YOU.
