The ribosome and (rarely) the vacuole.


An organelle is one of the specialised and memebrane-bound structures inside the cytoplasm of a cell. That means the cell membrane and cytoplasm can't be organelles. The only true organelles that all plant, animal and bacterial cells share are the ribosome and the vacuole. Of them, the vacuole is only present "in three genera of filamentous sulfur bacteria, the Thioploca , Beggiatoa and Thiomargarita ." https://en.wikipedia.org/wiki/Vacuole#Bacteria

The ribosome is the only common organelle of animal, plant and bacterial cells. The purpose of the ribosome is to synthesize proteins by linking together amino acids according to the instruction specified by the messenger RNA. The ribosomes in plant and animal cells are larger then the ones in bacterial cells.


I hope that helped!
