As explained at About, cytoplasm is important because it transports materials throughout the cell of an organism. Cytoplasm is also responsible for dissolving wastes within a cell.
According to Soft Schools, cytoplasm fosters the movement of cellular materials as well as the dissolving of wastes through the enzymes that are present within the gelatinous fluid. The shape of a cell is dependant upon the cytoplasm. Its jelly-like consistency also serves to hold all organelles in place, providing additional structural support for the cell.
Genetics Home Reference explains the makeup of cytoplasm, which consists of water, salts and organic materials. Although most cellular components are freely suspended within cytoplasm, some structures like mitochondria are separated from the substance by fine membranes. Science Daily states that all of the structures within the cytoplasm are known as organelles, and that each organelle has specific functions to execute within the cell.
Biology4Kids explains that cytoplasm was once referred to as protoplasm before it was understood that several different types of fluids are located within the cell. Cytoplasm is not to be confused with nucleoplasm, the fluid within the nucleus of a cell. Additional fluids are found within the mitochondria, Golgi apparatus and endoplasmic reticulum of the cell.
