BIL 150 Lecture Notes - Lecture 7: Collagen, Proteoglycan, Intermembrane Space
Document Summary
Moves them to the pole in cell division. Directs movement of cytoplasm in the cell. Vesicles travel along the monorails of the cytoskeleton. Move to either end of cell when cells are dividing. Core of microtubules sheathed by plasma membrane. A motor protein, dynein, drives the bending movements of a cilium or flagellum. Putting two cells together to form a strong structural component. Active as cement to bring cells together. Present exclusively in certain proteins and plants. Animal cells do not have cell wall. Cellulose fibers embedded in other polysaccharides and proteins. Lack cells walls so they have ecm. Help in attaching cells to the base; come together. Support adhesion movement regulation. Sponges were broken down into individual cells. Cells from both sponges were swirled together. The cells from each sponge sorted themselves out. Neighboring cells interact and communicate through direct physical constance. Prevents leakage of fluid in intermembrane space.
