the plasma membrane is an outer boundary that separates the interior of a cell from its external environment and is found in all cells. the molecules that make up the plasma membrane have a unique quality that helps to ensure the integrity of the cell. considering the structure of the plasma membrane, which of the statements best explains why human cells do not dissolve in water?



Answer :

Water is repelled by the phospholipids in the plasma membrane's fatty acid tail regions.

The cell membrane, which is also referred to as the plasma membrane (PM), cytoplasmic membrane, or plasmalemma, is a biological membrane that isolates and safeguards the interior of all cells from the external environment (the extracellular space). The cell membrane is a lipid bilayer made up of two phospholipid layers with cholesterols (a lipid component) positioned between them to maintain the proper fluidity of the membrane at varying temperatures.

Membranes also contain membrane proteins, which include integral proteins that span the membrane and function as membrane transporters as well as peripheral proteins that slackly attach to the exterior (peripheral) side of the cell membrane and function as enzymes to promote interaction with the surrounding environment. Membranes also contain lipids, which are the main structural component of cells.

The cell membrane, the movement of ions, the movement of ions, the movement of ions, the movement of ions, and the selectivelymph. Additionally, cell membranes act as the attachment surface for a number of extracellular structures, such as the cell wall and the carbohydrate layer known as the glycocalyx, as well as the intracellular web of protein fibers known as the cytoskeleton. These extracellular structures include cell adhesion, ion conductivity, and cell signaling. Synthetic biology is the study of reassembling cell membranes artificially.
