The mitochondria, ribosome, nucelus, endoplasmic reticulum, golgi apparatus, vacuole, flagellum, and chloroplast.


There are four types of Eukaryotic cells: Animal, Plant, Fungi and Protists. Together, they ususally have these organelles in common - the nucleus, mitochondria, golgi apparatus, ribosomes, endoplasmic reticulum, peroxisome and vacuole. The chloroplast is found in plant and some protist cells, and the flagellum is found in some eukaryotic cells.

There are other organelles as well, such as the lysosome, acrosome, nucleolus, peroxisome and others, however they play a minor role in the cell compared to the organelles mentioned above.

Some biologists like to have a strict defintion of organelles as "membrane-bound," which would stop ribosomes and the nucleolus from being organelles.

Other biologists use an even more limited definiton, saying organelles are "only those that are containing deoxyribonucleic acid (DNA), having originated from formerly autonomous microscopic organisms acquired via endosymbiosis ."

This would mean there are only two types of cells: Mitochondrian, and Plastids (chloroplasts.)
