Which is a characteristic of plants? They are unicellular. They are made up of prokaryotic cells. They have chloroplasts. They possess mobility.

They have chloroplasts. They do not possess mobility because they cannot just stand up and walk to the nearest river. Unicellular organisms are very small, and most organisms are multi-cellular, including plants. Plants, animals, and fungi are eukaryotic, but only bacteria is prokaryotic. So therefore, choice 3 is correct.
