Intracellular fluid is limited only to the interior of the cell, and the cell membrane is the boundary of cytosol.The membranes of organelles separate cytosol from the matrices of organelles. Many of the metabolic pathways take place in the intracellular fluid, in both prokaryotes and eukaryotes.ll in all the true essence at ideal concentration in the interior of anything makes sure that its real potentials are pursued, which directly applies to the intracellular fluid and the performance of the cell.
