Oxidation takes place at anode and reduction at cathode - yes, it is correct.
There is no anode and/or cathode when you simply have a tin can in air. There has to be two poles (usually 2 metals that differ in reduction potential). Here you have only 1 metal. But, in a voltaic (galvanic) cell, oxidation takes place at the anode, and reduction takes place at the cathode.
Anode is positive and cathode is negative. Cathode is the longest led frame. Anode is where the oxidation reaction takes place while cathode is where the reduction reaction takes place or in a galvanic corrosion the anode is the metal that corrodes while the cathode is protected.
Oxidation of water occurs wherever there is photosynthesis. Plants and organisms that perform photosynthesis take in water and other minerals and convert them to sugar, but the conversion to sugar creates a biproduct of free oxygen. This oxygen then oxidizes the water.
The cathode.
according to me anode should be oxidizing electrode as oxidation reaction takes place on anode
Oxidation takes place at the anode and reduction takes place at the cathode, so elemental metal will form at the cathode, and elemental metal will form into ions at the anode.

A: at the anode in both an electrolytic cell and a voltaic cell

It can be complicated depending on the type of cell one is looking at. However, here is my simple explanation.The anode is the electrode where the oxidation reaction takes place, and oxidation is the loss of electrons, so in a galvanic cell the anode is a source of free electrons and so it is negatively charged.The cathode is the electrode where reduction takes place, and reduction is the gain of electrons, so in a galvanic cell the cathode is positively charge and ready to accept negatively charged electrons.Now, the anode isn't always negative and the cathode isn't always positive. It has to do with the direction of current flow (anode = current in, cathode = current out). In an electrolytic cell, the charges on the anode and the cathode are reversed from that seen in a galvanic cell.

The cathode.
An oxidation half-reaction
according to me anode should be oxidizing electrode as oxidation reaction takes place on anode
Reduction occurs at the cathode in an electrolytic cell.
These reactions are called redox reactions.Isolated reduction/oxidation is not possible.
Oxidation is characterized by the loss of electrons, and reduction is characterized by the gain of electrons. Since there must be an electron loser and an electron receiver, oxidation and reduction are always complimentary.
