Fluid mosaic model of cell membrane is given by

✅ Explanation: The fluid mosaic model, proposed by Singer and Nicholson in 1972, describes the cell membrane as a dynamic structure composed of a phospholipid bilayer with embedded proteins. These proteins can move laterally within the membrane, giving it a fluid-like nature.

🔑Key Points :
-According to the fluid mosaic model, the quasi-fluid nature of lipid enables lateral movement of protein within the overall, lipid bilayer.
-This ability to move within the membrane is measured as its fluidity.
-The fluid mosaic model was proposed by S.J. Singer and Garth L Nicolson.
-This model explains the structure of the plasma membrane of animal cells as a mosaic of components such as phospholipids, proteins, cholesterol, and carbohydrates, these components give a fluid character to the membranes.

• 🛑Additional Information:
-Cell Theory-
– In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells.
-Cells are the basic structural/organizational unit of all organisms, and all cells come from pre-existing cells.
-The classical cell theory was proposed by Theodor Schwann in 1839. 
-Model of Golgi bodies-
-​In this model, the Golgi is viewed as a set of stable compartments that work together, each compartment has a unique collection of enzymes that work to modify protein cargo 
-The Golgi apparatus also known as the Golgi complex, Golgi body, or simply the Golgi is an organelle found in most eukaryotic cells.
-It was identified in 1897 by the Italian scientist Camillo Golgi and was named after him in 1898.
-Vacuole Theory-
-​A vacuole stores salts, minerals, pigments, and proteins within the cell.
-The solution that fills a vacuole is known as the cell sap.
-The vacuole is also filled with protons from the cytosol that helps in maintaining an acidic environment within the cell.
