Organelles are specialized structures within cells that perform specific functions. Here are some examples:

* Nucleus: Contains the cell's genetic material (DNA).

* Mitochondria: Powerhouse of the cell, responsible for energy production.

* Ribosomes: Sites of protein synthesis.

* Golgi apparatus: Processes and packages proteins.

* Endoplasmic reticulum (ER): A network of membranes involved in protein and lipid synthesis.

* Lysosomes: Contain enzymes for breaking down waste materials.

* Chloroplasts: Found in plant cells, responsible for photosynthesis.
