What keeps molecules concentrated, limiting disorder? ?

Cell membrane

Explanation:

The cell membrane is a thin lipoprotein film formed by phospholipids and proteins, whose thickness varies between 7.5 to 10 nanometers, delimiting the cytoplasm of all types of cells (bacteria, algae, fungi, protozoa, animals and vegetables), receiving various designations: plasmalema, plasma membrane or cytoplasmic membrane.

Within the eukaryotic cells the cytoplasm has organelles and channels made up of membranes similar to those surrounding the cell, being responsible for the selection of everything that enters and leaves the cell.

In this case, we can say that the plasma membrane is responsible for keeping the molecules concentrated, limiting any disturbance.

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.
