Which moleclues prevents cell membranes from Dissvoling in water?

lipid molecules

Explanation:

lipid molecules prevent membrane from dissolving and they are also known as phospholipids.

A lipid molecule could be imagined as rectangle. With one end i.e the bottom of the lipid molecule that is hydrophilic which means they are water-loving.

The other end of the head of the lipid molecule which is hydrophobic, which is the non-polar and water-fearing end of the molecule.

Within protective layer surrounding the outside cell(Cell membrane) there are large amounts of lipid molecules. Phospholipids are the most abundant that prevent membrane from dissolving.

Water is a polar solvent and prefers dissolving polar molecules such as salt but Lipids is a non polar molecule and can't be dissolved by water the presence in abundance prevents dissolution.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
