A legislative assembly is distinguished from an executive branch in its functions and responsibilities. The legislative assembly, often composed of elected representatives, is responsible for creating laws, debating policy issues, and representing the electorate. In contrast, the executive branch, led by the head of state or government, implements and enforces laws, directs government operations, and oversees public administration. While both branches play crucial roles in governance, their structures and purposes differ significantly, contributing to a system of checks and balances.
