IB Biology B2.1 - Membranes and Membranes Transport Questions And Answers Rated A+ Why do cells need membranes? • To distinguish itself from its surroundings • To be selective about what gets in and out How do lipids assemble to form a semipermeable membrane? Being cylindrical, phospholipid molecules spontaneously form bilayers in aqueous environments. In this energetically most-favorable arrangement, the hydrophilic heads face the water at each surface of the bilayer, and the ...
