1. Nucleus:
* Function: Contains the cell's DNA (genetic material) and controls the cell's activities. It also directs protein synthesis.
2. Ribosomes:
* Function: Site of protein synthesis. They read the genetic code from mRNA and assemble amino acids into proteins.
3. Endoplasmic Reticulum (ER):
* Function: A network of membranes involved in protein and lipid synthesis, folding, and transport.
* Rough ER: Contains ribosomes and modifies and transports proteins.
* Smooth ER: Synthesizes lipids and steroids, detoxifies drugs and poisons, and stores calcium ions.
4. Golgi Apparatus:
* Function: Processes, packages, and sorts proteins and lipids from the ER, preparing them for export or delivery to other parts of the cell.
5. Mitochondria:
* Function: The powerhouse of the cell. They convert nutrients into energy (ATP) through cellular respiration.
6. Lysosomes:
* Function: Contain enzymes that break down waste materials, cellular debris, and engulfed pathogens.
7. Vacuoles:
* Function: Store water, nutrients, and waste products. In plant cells, they also provide structural support.
8. Cytoskeleton:
* Function: Provides structural support, maintains cell shape, and facilitates movement of organelles within the cell.
9. Cell Membrane:
* Function: Acts as a barrier between the cell's interior and the external environment, controlling what enters and exits the cell.
10. Centrioles (in animal cells):
* Function: Important for cell division, playing a role in the formation of spindle fibers.
This is not an exhaustive list, but it covers the major organelles and their primary functions. Remember, each organelle plays a vital role in keeping the cell alive and functioning.
