Explanation:

Though the President of India is not a member of either House of Parliament and does not sit in the Parliament to attend its meetings, he is an integral part of the Parliament. This is because a bill passed by both the Houses of Parliament cannot become law without the President’s assent. He also performs certain functions relating to the proceedings of the Parliament, for example, he summons and prorogues both the Houses, dissolves the Lok Sabha, addresses both the Houses, issues ordinances when they are not in session, and so on. The Speaker is elected by the Lok Sabha from amongst its members (as soon as may be, after its first sitting). Whenever the office of the Speaker falls vacant, the Lok Sabha elects another member to fill the vacancy. He presides over a joint setting of the two Houses of Parliament. Such a sitting is summoned by the President to settle a deadlock between the two Houses on a bill. He adjourns the House or suspends the meeting in absence of a quorum. The quorum to constitute a meeting of the House is one-tenth of the total strength of the House.
