Students will…
Explain that cells take in nutrients in order to grow and divide and to make needed materials.
Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, and mitochondria) to basic
cell functions.
Explain that tissues, organs, and organ systems serve the needs cells have for oxygen, food, and
waste removal.
