The Parliament of the Indian Union consists of two Houses: the Rajya Sabha (Council of States) and the Lok Sabha (House of the People).These two houses and the President together constitute the Parliament of India. The object behind the creation of the Rajya Sabha is to provide for a second chamber so that legislation passed by one House can be reviewed and altered if needed by the other.Rajya Sabha is a continuing chamber as it is a permanent body not subject to dissolution. One-third of its members retire at the end of every two years and elections are held for the vacant positions. A member of Rajya Sabha has a six year term, unless he resigns or is disqualified.

Lok Sabha is the lower or the popular chamber of the Indian Parliament. Under the Constitution not more than 525 members are to be chosen by direct election from territorial constituencies in the States and not more than 20 members to represent the Union Territories. In addition, two members of the Anglo-Indian community may be nominated by the President if he is of the opinion that the community is not adequately represented in the Lok Sabha.   

2.The word legislature comes from the Latin word for "law" — legis. In the US, each state has a legislature — made up of the elected state senators and assemblymen or women, or representatives. The US Congress is the national legislature. These bodies, whose members are often referred to as "law-makers," make up the legislative branch of government, as distinct from the executive and judicial branches.
