(F, T, T, F) $(1)$ False $(F)$: Galvanic cells convert chemical energy to electrical energy,while electrolytic cells convert electrical energy to chemical energy.
$(2)$ True $(T)$: In an electrolytic cell,the polarity is reversed compared to a galvanic cell; the electrode connected to the positive terminal is the anode,and the one connected to the negative terminal is the cathode.
$(3)$ True $(T)$: In a galvanic cell,electrons flow from anode to cathode,whereas in an electrolytic cell,an external power source forces electrons to flow in the opposite direction.
$(4)$ False $(F)$: The standard potential of a Daniell cell is $1.1 \ V$. If an external voltage of $2.0 \ V$ (which is greater than $1.1 \ V$) is applied,the cell reaction reverses,and the cell acts as an electrolytic cell.
