How Many Branches Does the Legislature Have?

The legislature is a single branch of government (the legislative branch), not divided into "two branches."

In bicameral systems (e.g., US Congress, UK Parliament, Australian Parliament), the legislature comprises two chambers/houses (e.g., Senate & House of Representatives), but together they form one branch of the three-branch separation of powers (Legislative, Executive, Judicial).

Unicameral legislatures (e.g., New Zealand, Sweden, Nebraska) have one chamber. The key point: legislature = one branch; chambers = internal structure.
