"Positive" and "negative" are just terms that we assign to define a fundamental difference in the way charges interact. We could just as well call them "up" and "down", or "blue" and "red" - the words you chose don't affect the physics.
The point is that they are different and that difference is what causes the unique interactions we observe.
In a galvanic cell, the anode is the electrode where oxidation occurs. This is the site where electrons are released during the chemical reaction and flow towards the cathode. The anode is typically the negative terminal of the cell, as it donates electrons to the external circuit.
Zinc is the anode.
In a galvanic cell, the anode is the electrode where oxidation occurs, meaning it is the site where electrons are released. It is typically the negative terminal of the cell because it donates electrons to the external circuit. The anode is connected to the cathode, where reduction takes place, and overall, this flow of electrons generates electric current.
An electrolytic cell uses electrical energy to drive a non-spontaneous chemical reaction, typically involving the decomposition of compounds, while a galvanic (or voltaic) cell generates electrical energy from spontaneous chemical reactions. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a galvanic cell, the anode is negative and the cathode is positive. Additionally, electrolytic cells require an external power source, while galvanic cells operate independently by harnessing the energy from chemical reactions.

The significance of anode polarity in electrochemistry is that it determines the direction of electron flow in a galvanic cell or electrolytic cell. The anode is where oxidation occurs, and it is positively charged in a galvanic cell and negatively charged in an electrolytic cell. This polarity affects the overall reaction and the flow of ions in the cell.
