Biology

The cell membrane's structure significantly contributes to its function.

The selectively permeable nature (option B) is a key factor. The phospholipid bilayer forms the basic structure. The hydrophobic tails of phospholipids create a barrier to most polar substances. This allows the cell membrane to control which substances enter and leave the cell. Small non - polar molecules like oxygen and carbon dioxide can diffuse through the lipid bilayer, while ions and larger polar molecules require specific transport proteins to cross. <...
