Nucleus

Cytoplasm
The region between the cell membrane and the nucleus.
Mitochondria
"Powerhouses" of the cell because they produce most of the energy the cell needs to carry out its functions. Rod shaped organelles.

Chloroplasts
Captures energy from sunlight and uses it to produce food for the cell.
Vacuoles

Prokaryote
