All animals use organelles. Organelles are structures within cells that carry out specific functions.

Therefore, all animals are considered eukaryotic, meaning they have cells with a nucleus and other membrane-bound organelles.

Here are some examples of organelles found in animal cells:

* Nucleus: Contains genetic material (DNA)

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

* Ribosomes: Produce proteins

* Endoplasmic reticulum: Involved in protein and lipid synthesis

* Golgi apparatus: Modifies and packages proteins

* Lysosomes: Break down waste materials
