1. Cell membrane: Regulates what enters and exits the cell, maintaining homeostasis.
2. Endoplasmic reticulum: Synthesizes proteins (rough ER) and lipids (smooth ER); transports materials within the cell.
3. Ribosome: Synthesizes proteins by translating mRNA.
4. Golgi apparatus: Modifies, sorts, and packages proteins for secretion or delivery to other organelles.
5. Lysosome: Breaks down waste materials and cellular debris using digestive enzymes.
6. Mitochondria: Produces ATP through cellular respiration; powers cellular activities.
7. Microtubule: Provides structural support and aids in intracellular transport and cell division.
8. Nucleus: Stores genetic material (DNA) and controls cellular activities by regulating gene expression.
