The reason we laminate the iron cores in Transformers is because we want to limit what are called eddy currents. Transformers are basically two coils of wire wrapped around a core of iron. They work by induction. Induction occurs when current flows in one conductor (or one set of windings in the transformer) and the magnetic field that forms around that conductor (that set of windings) sweeps the other conductor (the other set of windings) and induces a voltage. In order to increase the effectiveness of the transformer, we need to improve the way the magnetic fields are coupled from one set of windings to the other set. Iron conducts magnetic lines of force well, so we use that to help conduct the magnetic lines of force from coil A to coil B. Problem is, iron is also a conductor, and it's being swept by the magnetic field as well. If we didn't use laminations, the iron core would provide a place for the magnetic lines to produce (induce) current, and that current flowing in the core would heat the core up really fast and waste energy. By laminating the cores, we break up the current paths within that core and limit eddy currents.
It does. We call this current, or currents, 'eddy currents', and they are minimised by using laminated cores.
If the transformer had a solid core it would build up eddy currents within the core possibly making the core itself rise in voltage. The laminations break up these eddy current circuits and prevent this.
It is the current transformer core meant for metering.

Insulation of laminated core is required to reduce the circulating current points due to touching the two plates. This results in more iron loss and heat produced

If, by 'one piece', you mean solid -as opposed to laminated- then the answer is that a solid core will have significantly-higher eddy current (circulating current) losses than a solid core.

The iron core of Transformers is laminated to reduce eddy currents, which cause a loss of energy.

by using the laminated core
iron core is used as an electromagnetic as electric energy is converted in to magnetic energy which in turn converted in to mechanical energy
There is a laminated iron core for the magnetic field and then a lot of enamelled copper wire. Step-up transformers use the same materials.
