Cytoplasm's main function within a cell is to act as the medium of suspension for its internal structures. These internal structures are called organelles and perform important functions like cellular respiration. The organelles themselves are not naturally buoyant, so protein filaments aid in keeping them afloat throughout the cell.
Cytoplasm is made up of a transparent material called cytosol and can be found in both plant and animal cells. Cytosol is composed of mostly water and makes up more than 60% of the cell. Cytoplasm has other functions within the cell that are no less important than its suspension duties. According to Science Control, everything that a cell produces or uses will travel through the cytoplasm. Organelles exchange chemicals through the cytoplasm, some of which are first broken down by the enzymes stored in the wide open suspension of the cellular liquid. The cytoplasm, which lies in the entirety of the cell between the plasma membrane and the nucleus, also serves as a protector of the organelles that it holds within itself. A cell suffers from impacts from neighboring cells or other outside forces. The cytoplasm acts as buffer during these collisions, solidifying its importance to the functionality and durability of a cell.
