![Page 66: Cell Structure A. There are three basic structures of all types of cells: 1. Cell membrane a. Contains a bilayer of lipids b. Is selectively permeable](https://reader035.vdocuments.mx/reader035/viewer/2022062421/56649e445503460f94b37ea8/html5/thumbnails/66.jpg)
Microfilaments
Dynamic strands of the protein actin
Attached to the cytoplasmic side of the plasma membrane
Braces and strengthens the cell surface
Attach to CAMs and function in endocytosis and exocytosis

Intermediate Filaments
Tough, insoluble protein fibers with high tensile strength
Resist pulling forces on the cell and help form desmosomes

Motor Molecules
Protein complexes that function in motility
Powered by ATP
Attach to receptors on organelles

12. Cilia and flagella
a. Hair-like projections that help move some types of cells.
Cilia act like oars

Flagella act like a whip to move the cell:
