The government of the Roman did not have a representative branch. The Romans did not practice in direct democracy like we do (electing representatives to sit in legislative bodies). They practiced direct democracy; that is, it was the people who, gathered in popular assemblies, voted directly on bills
No, the Roman republic did not have three branches of government. They only had two, hence the motto SPQR---the Senate and the Roman People. The Senate could roughly be defined as the upper branch and the popular assemblies could roughly be defined as the representative branch. The Praetors, who, among other things, corresponded to our judges or judicial branch of government, were a part of the Senatorial branch of government.
The Senate gave advice on government activities to the executive branch of the Roman government.
No branch of the Roman government represented the plebeians. The plebeian tribunes represented the plebeians. However, they were not a branch of the government. The did not have executive powers. The plebeians had had their own assembly, the Plebeian council.
it was republic (indirect democracy), so there was representative government with elected officials.
