Dear Student,
A Unicameral state legislature is a type of legislature in which only one house or central unit is involved in the decision making and implementation of laws. The unicameral state legislature that has only one house is State legislative assembly or the Vidhan Sabha.
In Bicameral State legislature, there are two houses namely the state legislative assembly (Vidhan sabha) and the state legislative council (Vidhan Parishad).
