Quick-reference summary β for full depth, see our detailed UPSC Polity notes.
The Governor is the constitutional head of a State, appointed by the President and holding office during the President's pleasure (Articles 153-162) β with no fixed term or impeachment process, unlike the President. Executive power is exercised on the aid and advice of the State Council of Ministers (Article 163), but the Governor retains discretionary powers wider than the President's, including reserving bills (Article 200) and recommending President's Rule (Article 356).
