Membranes And osmosis Lab 6 Flashcards
Phospholipid bilayer
Layer of lipids that contains a soluble phosphate group
Cellular membrane
Provide 3-D structure, support, and protection
Biochemical properties of the phospholipid bilayer
Provide the necessary characteristics to create a strong and flexible structure that enclosed primitive chemical reactions.
Cellular membrane allows -
Selective passage of material in the aqueous environments in which cells exist
Cellular membrane de limits-
The size of cells and controls the movement of diluted into and out cells
Diffusion
Random movement of molecules in a system
Molecules move from a-
Higher concentration to a region of lower concentration
Osmosis
Diffusion of water molecules through a semi permeable membrane
