Terms in this set (8) The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character.
Which describes the fluid mosaic model of the plasma membrane?
The fluid mosaic model describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments.
Which statement best describes the fluid mosaic model?
D is correct. The Fluid Mosaic Model describes the liquid-like movement of the lipids, proteins, and carbohydrates that make up the plasma membrane.
Which of the following is described by the fluid mosaic model nucleus?
The fluid mosaic model explains various observations regarding the structure of functional cell membranes. According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.
What is the fluid mosaic model simple definition?
The fluid mosaic model is a way of describing the structure of cell membranes. The model likens the membrane to a “mosaic” of different components, consisting of a fluid or elastic double layer made up of lipid molecules and large protein molecules. … Lipids and proteins are the basic building blocks of living cells.
Which of the following best describes how the structure of the fluid mosaic model of the cell membrane controls the movement of substances in and out of the cell?
Which of the following best describes how the structure of the fluid mosaic model of the cell membrane controls the movement of substances in and out of the cell? It contains enzymes, which are layered around the membrane and facilitate endocytosis.
Who proposed the fluid mosaic model of plasma membrane describe the fluid mosaic model of plasma membrane with the help of a Labelled diagram?
The fluid mosaic model was first proposed by S.J. Singer and Garth L. Nicolson in 1972 to explain the structure of the plasma membrane.

Which statement best describes the plasma membrane?
Which statement best describes the plasma membrane of a living plant cell? It selectively regulates the passage of substances into and out of the cell. This is also known as the cell membrane.
Which of the following best describes the structure of the plasma membrane quizlet?
Which of the following best describes the structure of the plasma membrane? The plasma membrane is a phospholipid bilayer surrounding the cell.
Which characteristic describes the plasma membrane of a cell?
The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell.
