A) Cholesterol helps maintain stability and fluidity of the cell membrane.
C) The cell membrane is selectively permeable, meaning it only allows certain substances to pass through.
F) Receptor sites on the cell membrane play a crucial role in cell communication by binding to specific molecules or signaling molecules. Glucose is not a major component of receptor sites. 
B, D, and E are incorrect statements. Phospholipids are a key component of cell membranes, microvilli are not involved in sweeping materials across the cell surface, and glucose is not a major component of receptor sites.
