What is cytosol and cytoplasm?
Apr 28, 2017 · This includes both cytosol – the fluid outside of the organelles – and the organelles themselves. Extracellular fluid – The fluid outside of a cell. A major function of the cell membrane is to separate the extracellular fluid from the cytosol, and ensure the proper composition of the cytosol.
Function. The cytosol is the site of multiple cell processes. Examples of these processes include signal transduction from the cell membrane to sites within the cell, such as the cell nucleus, or organelles. This compartment is also the site of many of the processes of cytokinesis, after the breakdown of the nuclear membrane in mitosis.
Nov 14, 2019 · It is involved in signal transduction between the cell membrane and the nucleus and organelles. It transports metabolites from their production site to other parts of the cell. It is important for cytokinesis, when the cell divides in mitosis. The cytosol plays a role in eukaryote metabolism.

The cell contains an array of cellular organelles, each one performing a unique function and helping to maintain the health and activity of the cell. The cytosol and organelles together compose the cell’s cytoplasm. Most organelles are surrounded by a lipid membrane similar to the cell membrane of the cell.

The cytoplasm comprises the contents of a cell between the plasma membrane and the nuclear envelope (a structure to be discussed shortly). It is made up of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals (Find it in Figures 5.3.1 5.3. 1 -5.3.3 5.3. 3 ).
A plasma membrane is a layer around a cell that prevents the cytoplasm from getting all mixed up with the outside environment. Plasma membrane (cell membrane) is made of two phospholipid layers, or a type of lipid with hydrophilic heads on the outside and hydrophobic tails inside.
Key terms. Structure and function of the cell membrane. The cell membrane is semipermeable (or selectively permeable). It is made of a phospholipid bilayer, along with other various lipids, proteins, and carbohydrates. Image modified from OpenStax Biology. Each phospholipid is amphipathic, with two hydrophobic tails and a hydrophilic head.
