A system whereby there is only one legislative chamber parliament is referred to as a unicameral legislature. In a unicameral legislature, there is only one house of parliament, which is responsible for making and passing laws. This is different from a bi-cameral legislature, where there are two separate houses of parliament, usually a lower and an upper chamber. The unicameral system is often found in smaller countries, or those with a less complex political system. It is believed to be more efficient and less expensive than a bicameral system, as it eliminates the need for two separate sets of lawmakers, staff, and facilities.
