Explain in just 5 lines. "Current can flow through metal conductors, Semiconductors and even in Gases and Liquids. Discuss what types of charges are responsible for flow of current in each matter?

The electric current flows by the net flow of electric charge.

Explanation:

Electric current is the process of flow of electron from negative pole to positive pole. As the flow of current is due to the movement of electron. The electron is negatively charged and hence to gets attracted to the positive charge. This movement from negative to positive charge produces the electric current. The same mechanism of migration of charged ion causes to flow electric current through metal conductors, Semiconductors and even in Gases and Liquids.
