3. How cell motility Works
Cell motility (movement) is mainly driven by a network of actin in the cell membrane.
This network is controlled by the Cytoskeleton
ACTiN is a protein that contracts through Polymerizaton
It relaxes through depolymerization

5. Movement Type #1- Pseudopodia
Definition – a temporary protrusion or retractile process of part of the cell’s cytoplasm
Example - amoeba

Amoeba eats Two paramecium:

6. Movement Type #2 – Flagellar movement
Definition – slender, whip-like appendage that helps microorganisms to move
Example – Euglena, sperm cells
Movement of Euglena in Phase Contrast
Two organisms using Flagella

7. Movement Type #3 - Cilia
Definition – minute, hair-like structures that often surround the cell like a fringe
Example – Paramecium, lung cells
Paramecium eating and moving
