Vedclass · Answer

(B) The correct answer is $B$. $A$ is correct: Osmosis is the movement of water across a semipermeable membrane,which depends on the solute concentration. $B$ is incorrect: Plasma membranes in plants are composed of lipids and proteins; they do not contain chitin. Chitin is a structural polysaccharide found in the cell walls of fungi and the exoskeletons of arthropods,not in plant plasma membranes. $C$ is correct: Biological membranes are primarily composed of a phospholipid bilayer with embedded proteins. $D$ is correct: Since the membrane is lipid-based,substances that are lipid-soluble (soluble in organic solvents) can diffuse through the membrane easily.
