Legislatures are formal bodies of government responsible for making laws. They consist of elected representatives who debate and vote on proposed legislation. In many countries, legislatures can be unicameral (one chamber) or bicameral (two chambers), such as the U.S. Congress, which includes the House of Representatives and the Senate. Legislatures also play a crucial role in representing the interests of citizens and overseeing the executive branch of government. They hold hearings, conduct investigations, and can influence public policy through their legislative powers. This process ensures that laws reflect the needs and values of the community.
