Here is a sketch of the functioning cell:

Zinc electrode (Zn) | Zinc sulfate solution (Zn^2+) || Copper (2) sulfate solution (Cu^2+) | Copper electrode (Cu)

At the anode (negative electrode), oxidation occurs, giving up electrons:

Zn(s) → Zn^2+(aq) + 2e^-

At the cathode (positive electrode), reduction occurs, accepting electrons:

Cu^2+(aq) + 2e^- → Cu(s)
