Is there a difference between the terms cytosol and cytoplasm?

...because I hear them used interchangeably.

Thanks!

Cytoplasm vs. cytosol

- cytoplasm includes everything in the cell except the nucleus
- cytosol is the soluble portion of the cytoplasm

Ah, I see. Thanks for the info. When I googled it, I found the Wikipedia definitions and didn't provide much help into their differences.

There is often much confusion between the cytoplasm and the cytosol. The cytoplasm is the fluid contained within the cell that holds and surround the cell's organelles in a liquid environment which is necessary for many of the cell's vital functions to occur. Some of the organelles that are held within the cytoplasm include the mitochondria, the golgi apparatus, the endoplasmic reticulum, and other organelles. One thing to note is that the nucleus isn't considered to be part of the cytoplasm because it contains it's own type of fluid-like material that is referred to as the nucleoplasm. The materials that are found within the cytoplasm are also typically found within the cell membrane. Typically, the cytoplasm contains materials that are known as cytoplasmic inclusions. These inclusions are typically starch granules, mineral crystals, or lipid droplets that are floating around within the cytoplasm.

When looking at the two, the cytosol is often confused as being the cytoplasm itself, and many individuals view the two as being synonymous. However, they cytosol is in fact just a part of the cytoplasm. The gel-like translucent fluid is what the cytosol really is. It is typically not enclosed within the organelles found within the cell. The cytosol is responsible for suspending the other elements contained within the cytoplasm, like the cytoplasmic inclusions and the cell organelles. Consisting of around 75% of the cell's total volume, the cytosol is composed of many different cellular components. Concentration gradients, cytoskeletal sieves, protein complexes, protein compartments, water, salts, organic compounds, and dissolved ions all consist of the contents of cytosol. Structurally, the cytosol consists mostly of water. However, it does house cytoskeleton filaments, which are necessary for maintaining the overall structure of the cell. In regards to function, the cytosol is also the location where many of the cell's chemical reactions occur. Transportation of metabolite and cell communication are among some of the important functions that occur within the cytosol.

2 year old thread tl&dr: cytosol = fluid part of cytoplasm.
