Our plasma membrane is said to be a "fluid mosaic." Describe the properties of our membranes that allow them to be a fluid mosaic.?

They are fluid because the various components in cell (and other) membranes aren't static. They can move around; therefore, they are described as fluid. The fluidity of the membrane can be increased by an increase in temperature. Both the phospholipids and proteins in the membrane can move.
The 'mosaic' part refers to the appearance of the membrane. Its basic structure is a bilayer of phospholipids. There are proteins that sit in this phospholipid bilayer. The appearance, especially based on diagrams, is described as a mosaic.
