The fluid mosaic model of the cell membrane can be made more rigid by increasing the amount of cholesterol in the membrane. Cholesterol helps to stabilize the membrane by reducing its fluidity and increasing its rigidity. Additionally, shorter and more saturated fatty acid chains in the phospholipids can also contribute to a more rigid membrane structure.
What else can I help you with?
Why is the model of a membrane shown in the transperency referred to as the fluid mosaic model?
The membrane is made out of several molecules - mainly phospholipids. Instead of being a rigid structure, the molecules within the membrane are constantly moving and changing places. This means the membrane appears like a fluid.
What is a fluid mosaic model?
Simply put, the fluid mosaic model is a description of the membrane of a cell. The fluid part refers to the phospholipids of a cell membrane, which, like liquid, flow. The mosaic part refers to proteins embedded in the phospholipid bilayer that act as conduits through which molecules enter and exit the cell.____________The currently accepted model of cell membrane structure, which envisions the membrane as a mosaic of individually inserted protein molecules drifting laterally in a fluid bilayer of phospholipids.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 i.e. the membrane is fluid.This model of the cell membrane was proposed by Singer and Nicolson in 1972, and has been supported by many experiments since then.model for cell membrane given by SJ singer and GL Nicholoson
The fluid mosaic model describes a structure with?
According to the fluid mosaic model, our cell membrane is a double membrane of phospho lipid molecules. Proteins are embedded in this layer. Cholesterol is also an important compone of this membrane.
Why is plasma membrane referred to as fluid mosaic model?
it is called that because albert mosaic improved to active the latest model.
Why is the plasma membrane referred to as fluid mosaic?
The plasma membrane is referred to as fluid mosaic because it is made up of a fluid lipid bilayer with embedded proteins that constantly move and shift in a mosaic pattern. The lipids and proteins can move laterally within the membrane, leading to its fluidity and dynamic nature.

Explain what a mosaic is and then explain why the term fluid mosaic model is used to describes the plasma membrane?
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.

What are the advantages and disadvantages of the fluid Mosaic model?
The fluid mosaic model describes the structure of the cell membrane as a fluid lipid bilayer with embedded proteins. Advantages: It allows for flexibility and movement of molecules within the membrane. It explains how various proteins can be embedded in the membrane to carry out specific functions. Disadvantages: It oversimplifies the complexity of the cell membrane, as there are other components beyond lipids and proteins. It doesn't fully account for the organization and interactions of membrane components in specific regions.
What is the principle of the fluid mosaic model of cell membrane structure?
The plasma membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid, but more like a 'fluid'. The membrane is depicted as mosaic because like a mosaic that is made up of many different parts the plasma membrane is composed of different kinds of macromolecules, such as integral proteins, peripheral proteins, glycoproteins, phospholipids, glycolipids, and in some cases cholesterol, lipoproteins.
Why is the plasma membrane referred to as fluid mosaic?
The plasma membrane is referred to as fluid mosaic because it is made up of a fluid lipid bilayer with embedded proteins that constantly move and shift in a mosaic pattern. The lipids and proteins can move laterally within the membrane, leading to its fluidity and dynamic nature.
Why is the cell membrane sometimes referred to as fluid mosaic?
The cell membrane is sometimes referred as "mosaic" because is a work of art made of individual tiles or other pieces assembled to form a picture or design.
What is the name of the model that is used to explain the structure cell membrane?
its a bi-lipid membrane, so its two sheets of fatty acids back to back. there are also steroids intermixed in the membrane and receptors sticking out of the cell that activate upon contact with various chemical receptors. they "activate" in different ways, but basically they trigger different chemicals or enzymes to be formed inside the cell. im not sure what model is used, models are only made to simplify a problem, but scientists basically know how most cells work, so im not sure what model is needed. There is a mathematical model of water diffusion through cells. that's based on concentration of solute on either side of the cell wall.
What do you call an art work with tiles?
A picture made with with tiles and stone is a mosaic.
