All executive and administrative offices, agencies, and instrumentalities of the executive department of state government and their respective functions, powers, and duties, except for the office of governor and lieutenant governor, shall be allocated by law among and within not more than twenty departments. Subsequently, all new powers or functions shall be assigned to departments, divisions, sections, or units in such manner as will tend to provide an orderly arrangement in the administrative organization of state government. Temporary commissions may be established by law and need not be allocated within a principal department.
