- Cell membrane: Controls what enters and leaves the cell.
- Nucleus: Contains the cell's genetic material (DNA) and controls cell activities.
- Nucleolus: Produces ribosomes within the nucleus.
- Cytoplasm: Gel-like substance that fills the cell and holds organelles in place.
- Mitochondria: Produces energy (ATP) for the cell through cellular respiration.
- Endoplasmic reticulum (rough): Synthesizes and transports proteins; studded with ribosomes.
- Golgi apparatus: Modifies, sorts, and packages proteins for secretion or use within the cell.
- Lysosome: Breaks down waste materials and cellular debris using digestive enzymes.
- Vacuole: Stores nutrients, waste products, and helps maintain turgor pressure.
- Ribosomes: Synthesize proteins by translating mRNA.
Parent Tip: Review the logic above to help your child master the concept of parts of the cell worksheet.
