Question

why is the model of the cell membrane referred to as?

A) fluid

B) A masaic

Answer 1

A) Because the phospholipids that form the cell membrane are a fluid substance, the membrane is also considered a fluid structure (similar to oil floating on the surface of water).

B) like a mosaic, the cell membrane is a complex structure made up of many different parts, such as proteins, phospholipids, and cholesterol. The relative amounts of these components vary from membrane to membrane, and the types of lipids in membranes can also vary.
