The mosaic pattern of the cell membrane viewed from above is caused by the arrangement of proteins, lipids, and other molecules. These components are not randomly distributed but rather organized in a specific manner, giving rise to the mosaic appearance. The pattern reflects the diverse functions and interactions of the molecules within the cell membrane.

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
Where should you use geotextile in roof above the membrane or below the membrane?
Geotextile should generally be placed above the roofing membrane to act as a protective barrier. It helps to prevent punctures or damage to the membrane from sharp objects like gravel or debris. Placing it below the membrane may not provide the same level of protection and could compromise the integrity of the roofing system.
What is a fluid mosaic?
It is a theory proposed S.J. Singer and Garth Nicolson in 1972 to explain the properties of a cell membrane. 1. Cell membranes are made of 2 layers of phospholipids. 2. A phospholipid is a large molecule, based on a triglyceride. It has a phosphate head which is water-loving and a fatty acid tail which repels water. 3. The phosphate head forms the outside of the layer and attracts water. 4. The fatty acid is repelled by the water and points towards the middle of the molecule: http://upload.wikimedia.org/wikipedia/commons/f/f0/Lipid_bilayer_section.gif Molecule is a part of the mosaic. If you looked at the membrane from above, it would look like a mosaic of phospholipid. The 'Tiles' are not joined and have gaps between them. Google Phospholipid Bilayer for more info.
What part of the protein is within the membrane itself?
The transmembrane domain of a protein is the part that spans the membrane, anchoring the protein within the lipid bilayer. This domain typically contains hydrophobic amino acids that interact with the hydrophobic interior of the membrane.
What is the altitude of polaris above the horizon at the tropic of cancer?
Polaris will be 23.5 degrees above the northern horizon when viewed from the Tropic of Cancer.
What does the fluid mosaic model describes?
It describes the structure of the cell membrane. It is called fluid because the individual phospholipid molecules can move freely within their own monolayer. It is called mosaic because of the pattern produced by the scattered protein molecules when the membrane is viewed from above.
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. '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.Read more: What_is_meant_by_the_term_'fluid_mosaic'
What is meant by the term 'fluid mosaic'?
The term "fluid mosaic" describes the structure of the cell membrane, composed of a fluid lipid bilayer with embedded proteins that are able to move within the membrane, giving it a dynamic and mosaic-like appearance. This characteristic allows for flexibility and adaptability in the cell membrane's functions, such as cell signaling and transport.
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.

Why is the cell membrane said to be a fluid mosaic?
The cell membrane is called a fluid mosaic because it is made up of a fluid phospholipid bilayer with proteins and other molecules interspersed throughout, giving it a mosaic-like appearance. The fluidity of the membrane allows for movement of molecules within it, contributing to its dynamic nature.
