1. Cell membrane: Regulates the passage of substances in and out of the cell, maintaining homeostasis.
2. Endoplasmic Reticulum: Synthesizes proteins (rough ER) and lipids (smooth ER), and transports them within the cell.
3. Ribosome: Site of protein synthesis, translating mRNA into polypeptide chains.
4. Golgi Apparatus: Modifies, sorts, and packages proteins for secretion or delivery to other organelles.
5. Lysosome: Contains digestive enzymes that break down waste materials, cellular debris, and foreign invaders.
6. Microtubule: Provides structural support, facilitates intracellular transport, and forms the mitotic spindle during cell division.
7. Mitochondria: Produces ATP through cellular respiration, serving as the cell’s primary energy source.
8. Nucleus: Houses DNA and controls gene expression, regulating cell growth, metabolism, and reproduction.
