Question

Quizplus · Accepted Answer

The plasma membrane is a selectively permeable membrane that controls the flow of materials in and out of the cell. It is made up of a lipid bilayer and various proteins that facilitate transport of molecules. The nucleus contains the genetic material, but does not control the movement of materials in and out of the cell. The cytoplasm and endoplasmic reticulum are important for various cellular functions, but do not have direct control over the plasma membrane.
