Powers and duties of the legislative, executive, and judicial branch?

http://www.usconstitution.cc/

The separation of powers is a model for the governance of a state). Under this model, the state is divided into branches, each with separate and independent powers and areas of responsibility so that no branch has more power than the other branches. The normal division of branches is into a legislature, an executive, and a judiciary.
The three branches of government (legislative, executive, judicial) exist largely independent of each other, with their own prerogatives, domains of activity, and exercises of control over each other.
• The legislative body (Parliament/ Congress) has control over the executive, finances, and has judiciary powers, it also has control of the way the judiciary works.
• The judiciary often has control of laws not being contradictory to the constitution or other laws and it has the power to correct and control the way the executive body exercises its powers (to execute the law)
• The Executive looks after the implementation, execution of Govt. policy, plan, programme formulated by the Legislative Body
