Cytoplasmic membrane systems are biological membranes that separate and protect the interior of a cell from the outside environment. They are also known as the plasma membrane or cell membrane. Cytoplasmic membranes are made up of roughly equal parts lipids and proteins. The main lipid components are phospholipids, which vary in length, saturation, and branching.
Cytoplasmic membranes have several functions, including: Protecting the cell's inner components Acting as a barrier to import nutrients and export wastes Providing selective permeability Producing some energy Regulating the passage of solutes between the cell and the outer environment
Substances can cross the cytoplasmic membrane of eukaryotic cells by: Simple diffusion, Osmosis, Passive transport, Active transport, Endocytosis, Exocytosis.
