The cell membrane, also called the plasma membrane,is made mostly of lipids. The lipids found in cell membranes are specifically called phospholipids. These lipids are arranged in a double lipid layer known as the phospholipid bilayer. Each phospholipid has a hydrophilic(water-attracting) head and two hydrophobic(water-repelling) tails.

All cells have three basic parts: a. A plasma membrane separates each cell from the environment, permits the flow of molecules across the membrane, and contains receptors that can affect the cell’s activities. b. A DNA-containing region occupies a portion of the interior. c. The cytoplasm contains membrane-bound compartments (except bacteria), particles, and filaments–all bathed in a ...

Sometimes widgets don't turn out right, and the "rejects" are sent to the scrap yard where they are broken down for parts or destroyed altogether. The town powers the widget shops and carts from a hydraulic dam that is in the city. The entire city is enclosed by a large wooden fence, only the postal trucks (and citizens with proper passports) are allowed outside the city.

Some of these particles hit the plasma membrane. If they are small – like oxygen and carbon dioxide molecules – and do not have an electrical charge, they can easily slip through the phospholipid bilayer. Facilitated Diffusion. Oxygen and carbon dioxide have small molecules with no electrical charge, and can easily pass through the phospholipid bilayer. However, many other molecules or ...
