Membranes are sheets of tissue. Membranes cover surfaces, line body cavities, and surround organs. Membranes are classified as epithelial membranes or connective tissue membranes. The epithelial membranes include cutaneous (skin), mucous, and serous membranes. Explain how  water and other nutrients move through memebranes.

Water moves across a permeable barrier during osmosis to equalize the solute concentration on each side of the membrane. Nutrients, on the other hand, are absorbed across a barrier by a process known as diffusion

Explanation:

Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. Diffusion is the process by which atoms or molecules move from an area of high concentration to low concentration
