What is the function of cytoplasm?
Cytoplasm is a substance made largely of protein and water that fills the otherwise-empty spaces in a cell's body. Since the cell is a membrane with functioning organelles inside it, without the cytoplasm the cell would be flaccid and the organelles would be subject to impact and other harm. The cytoplasm acts to cushion the organelles, keep the cell at a certain level of inflation, and also to transport nutrients and other substances through itself. Cytoplasm is seen in all types of cells, eukaryotic and prokaryotic, and acts as the medium in which most functions of the cell occur. Two important parts of cytoplasm structure are the cytosol and the cytoskeleton. The cytosol is the bulk of the cytoplasm, and is all the fluid that is not inside the organelles; this is the main transport medium for nutrients and keeps the cell at a specific level of inflation. The cytoskeleton is the structure of the cell that helps it to keep its shape and to move around in its surrounding environment; the cytoskeleton also plays an important role in cell division.
