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.
The lamination core is used in a transformer is mainly to reduce the eddy current loss. By doing so we literally increasing the effective resistance for eddy current.thus there is reduction in eddy current.
Lamination is used for the core of transformers because you want good ferromagnetic coupling, but you do not want electrical continuity.
If you look very closely, you will notice that the laminations are E's, stacked in alternating, opposite directions, and that they are insulated from each other. If they were allowed to touch each other, they would complete a circuit and constitute a one-turn short circuit which would drastically reduce the Q of the transformer.

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.
choke
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.

They indicate the laminated metal core upon which the windings are wound.

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.
