The Romans kept dogs as pets. The famous dog mosaic had "cave canem" written on it, which means beware of the dog.

Which model of the plasma membrane is currently the most accepted?

The fluid mosaic model is currently the most accepted model of the plasma membrane. It describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that are able to move and interact within the membrane.


What fluid mosaic model shown above describes the structure and function of?

The fluid mosaic model describes the structure of the cell membrane, showing a dynamic mosaic of lipids and proteins that can move freely within the bilayer. This model highlights the membrane's fluidity and ability to regulate the passage of molecules in and out of the cell, crucial for maintaining cellular homeostasis.


What is meant by the term 'fluid mosaic'?

Fluid mosaic is a term used to describe the current model of the cell membrane. Cell membranes are basically double layers (bilayers) of molecules called phospholipids. 'Floating' in the phospholipid bilayer are molecules of protein. a mosaic is a structure made up of many different parts. Viewed from above the membrane would look something like a mosaic - a 'sea' of lipid with many 'islands' of protein. The lipid bilayer is not rigid, and the lipid and protein molecules are able to move sideways in the membrane ie the membrane is fluid. This model of the cell membrane was proposed by Singer and Nicolson in 1972, and has been suported by many experiments since then.

Where did mosaic originate from?

Mosaic art can be traced back to ancient Mesopotamia, dating as far back as the 3rd millennium BCE. The art form was widely used by various cultures, including the Greeks and Romans, to create decorative patterns and images using small pieces of colored glass, stone, or other materials.


Fluid mosaic model of a cell membrane?

Its called "the fluid mosaic model" of the cell membrane. This describes the clumping together of phospholipids to form rafts and their motion (along with single phospholipids) throughout the membrane.
