The Parliament consists of the President, the Council of States (Rajya Sabha) and the Council of the People (Lok Sabha). Though the President is not a member of either House of the Parliament, he is an essential part of it. He not only summons the two Houses of Parliament and dissolves the house of the People, but also gives his assent before any legislation can take effect. The two houses sit separately and are constituted on different principles.

Article-79: Constitution of Parliament.—

There shall be a Parliament for the Union which shall consist of the President and two Houses to be known respectively as the Council of States and the House of the People. 

Functions of the parliament

The Indian Constitution provides for a close link between the Executive and the Legislature. The Members of Council of Ministers are drawn from the Parliament and exercises the real executive power as long as it enjoys the confidence of the Lok Sabha. Thus the Parliament provides the Cabinet and also controls it.  By providing a platform it enables the representatives of the people to deliberate on the policies of the Government and on the intended legislation. It acts as an organ of information, and the information provided on the floor of the Parliament is authoritative. One of the most important functions of the Parliament is enactment of laws. It is the sole authority to authorize to raise revenue and to approve expenditure.
