The plasma membrane surrounds the cytoplasm of living cells‚ physically separating the intracellular components from the extracellular environment. It also plays a role in anchoring the cytoskeleton provide shape to the cell‚ and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The plasma membrane helps maintain homeostasis by diffusion and osmosis. Osmosis is the diffusion of water across a membrane. Diffusion is the process by which molecules

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister

is to determine the stress that various alcohols have on biological membranes. Membranes within cells are composed mainly of lipids and proteins and often serve to help maintain order within a cell by containing cellular materials. Different membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains a watersoluble red pigment‚ betacyanin
