Nucleus
Mitochondria (singular mitochondrion)
Ribosomes
Plant cells contain the following additional structures
Cell wall
Chloroplasts
Permanent vacuole
When viewed under a microscope the structures inside a plant cell are visible. Ribosomes and mitochondria are too small to view under a light microscope but are visible with the higher resolution of an electron microscope.
