I can't really tell you the exact answer because you don't have the choices listed but I can tell you that the cytoplasm is a jelly-like fluid that fills in the space between the nucleus and plasma membrane. It also has two functions. One is to help maintain the shape of the cell and support the internal structures, and the other one is to store many of the chemicals that are essential for the cell's life. Some of the things it stores are protein filaments (which form the cytoskeleton), soluble proteins, enzymes, fatty acids, sugars, amino acids, and salts. If you still don't know, just tell me the choices you have and I can help you that way. Hope this helps!
