| *Flagellum | A microscopic hair-like organelle used by cells and microorganisms for movement. (LONG) |
| *Cilia | Hair-like structures that extend from the cell body into the fluid surrounding the cell, which is responsible for the cell locomotion for eukaryotic cells. (Multiple short hairs) |
| Membrane-bound organelles | Organelles that contain their own nucleus, mitochondria, endoplasmic reticulum, lysosomes, vacuoles, and golgi apparatus. |
