Definition, Function, Structure Vs Cell Wall Definition: What is the Plasma Membrane?Essentially, the plasma membrane refers to the cell membrane that defines the boundaries of a cell and cell organelles. As such, it forms a barrier, with controlled interaction, between two aqueous compartments; ...
The versatile function of the cell membrane depends on its fluid nature, and this property is also responsible for the development of lipid-protein domains of the cell membrane, as we shall see shortly. The majority of fats in the cell membrane are phospholipids, which are composed of a ...
A geometrically simple cell, such as a small and round neuron without much processes, or a red blood cell, is isopotential, meaning that the membrane potential at each point inside the cell is the same. For cells of more complex geometry, such as an elongated muscle cell, a long nerve ...
Cells being specialized is essential for if they were not specialized, then the cell would contain additional organelles and require more energy to function. However, eukaryotic cells have membrane bound organelles such as a nucleus, mitochondria, chloroplast, Golgi apparatus, and lysosomes. A ...
