Final answer:
The Majles is the legislative body of Iran, responsible for making laws, while the Guardian Council ensures that these laws are in accordance with the Iranian Constitution and Islamic principles.
Step-by-step explanation:
The Majles and the Guardian Council are two key institutions in the Iranian political system. The Majles, also known as the Islamic Consultative Assembly, is the legislative body of Iran that is responsible for making laws. It is composed of elected representatives from different constituencies across the country.
On the other hand, the Guardian Council is a powerful body that consists of 12 members, with half of them appointed by the Supreme Leader and the other half nominated by the judiciary and approved by the Majles.
The Guardian Council's main role is to ensure that all laws passed by the Majles are in accordance with the Iranian Constitution and Islamic principles.
