Final answer:
Article I of the Constitution establishes the legislative branch, creating Congress as a bicameral body with the Senate and the House of Representatives, responsible for making laws.
Step-by-step explanation:
The part of the Constitution that establishes the legislative branch is Article I. Article I dictates that all legislative powers shall be vested in Congress, creating a bicameral body composed of the Senate and the House of Representatives. To become law, legislation must be passed by both of these bodies and then approved by the president.
Article I specifies the structure, powers, and limitations of Congress, in contrast to Article II, which outlines the powers of the president, and Article III, which establishes the judicial branch. The bicameral nature of Congress was chosen to balance the powers between the states and the populace, with the Senate providing equal representation for all states and the House of Representatives apportioned according to state populations.
It's important to note that the U.S. Constitution is divided into the Preamble, the Articles that lay out the structure of the government, and the Amendments. Article I is central to the legislative power and role of Congress in the federal government. Article I outlines the powers and structure of Congress, which is the lawmaking branch of the government. It establishes that Congress is bicameral, consisting of two houses - the Senate and the House of Representatives.
To pass a law, proposed legislation must be approved by both the House and the Senate, and be signed by the president or not vetoed.
