Organelles are specialized subunits within a cell that have specific functions. Some examples of organelles include:

* Mitochondria: Powerhouse of the cell, responsible for energy production (ATP)

* Ribosomes: Sites of protein synthesis

* Golgi apparatus: Processes and packages proteins

* Endoplasmic reticulum: Network of membranes involved in protein synthesis and lipid metabolism

* Lysosomes: Contain enzymes for breaking down waste materials

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

* Centrioles: Involved in cell division

* Vacuoles: Storage compartments for water, nutrients, and waste products
