1. Nucleus:
- Function: Contains the cell's genetic material (DNA) in the form of chromosomes. Controls cellular activities by directing protein synthesis.
2. Nucleolus:
- Function: Produces ribosomes, which are essential for protein synthesis.
3. Ribosomes:
- Function: Sites of protein synthesis. They translate the genetic code from mRNA into amino acid chains.
4. Endoplasmic Reticulum (ER):
- Rough ER: Studded with ribosomes and involved in protein synthesis, folding, and modification.
- Smooth ER: Lacks ribosomes and plays roles in lipid synthesis, detoxification, and calcium storage.
5. Golgi Apparatus:
- Function: Processes, packages, and sorts proteins and lipids synthesized by the ER. Modifies and transports them to their final destinations.
6. Lysosomes:
- Function: Contain digestive enzymes that break down cellular waste products, worn-out organelles, and engulfed materials.
7. Vacuoles:
- Function: Store water, nutrients, and waste products. Maintain cell turgor pressure in plant cells.
8. Mitochondria:
- Function: Powerhouses of the cell. They produce energy (ATP) through cellular respiration, utilizing glucose and oxygen.
9. Chloroplasts:
- Function: Found in plant cells, these organelles perform photosynthesis. They convert light energy into chemical energy stored in glucose.
10. Cell Wall:
- Function: Provides structural support and protection to plant cells. Regulates cell growth and prevents bursting due to osmotic pressure.
11. Cytoskeleton:
- Function: Provides structural support and shape to the cell. Involved in cell movement, organelle transport, and cell division.
12. Plasma Membrane:
- Function: Regulates the passage of substances into and out of the cell. Maintains cell integrity and provides a boundary between the cell and its environment.
13. Centrioles:
- Function: Involved in the organization of microtubules during cell division. Help form the spindle fibers that separate chromosomes.
14. Peroxisomes:
- Function: Contain enzymes that break down fatty acids and detoxify harmful substances. They also play a role in cellular respiration.
15. Cilia and Flagella:
- Function: Hair-like projections that aid in cell movement. Cilia are short and numerous, while flagella are long and few in number.
Note: The specific organelles present and their functions can vary slightly depending on the type of cell.
