A: Cytoplasm has many functions in both prokaryotic and eukaryotic cells, including aiding in the movement of cellular materials and transporting the genetic material and products of cellular respiration. It also acts as a liquid medium to suspend organelles and helps cells expand during reproduction.
In cell biology, the cytoplasm is the material within a living cell, excluding the cell nucleus. It comprises cytosol (the gel-like substance enclosed within the cell membrane) and the organelles â the cell's internal sub-structures. All of the contents of the cells of prokaryotic organisms (such as bacteria, which lack a cell nucleus) are contained within the cytoplasm. Within the cells of eukaryotic organisms the contents of the cell nucleus are separated from the cytoplasm, and are then called the nucleoplasm. The cytoplasm is about 80% water and usually colorless.
