What organelles are expected to be found in eukaryotes but not in prokaryotes?

Expert Answers

Prokaryotes are unicellular organisms that do not have a nucleus nor organelles. Therefore, any organelle would be found in a eukaryote but not a prokaryote. Thus, my response will consist of listing several organelles and their functions:

- The nucleus is the organelles that houses genetic material known as DNA (deoxyribose nucleic acid). 

- Ribosomes help in the translation of RNA to form proteins. This is the one organelle that is present within a prokaryote. 

- The Golgi apparatus and endoplasmic reticulum (otherwise known as the ER) help to synthesize (make) and package proteins and lipids. 

- Lysosome clean toxins within the cell. This is easy to remember because lysosome sounds like the common household cleaner called Lysol. 

- Mitochondria use glucose and oxygen to make water, carbon dioxide, and an energy source known as ATP. 

This is by no means an all-inclusive list, but I hope that it is a good start!

Prokaryotes are single-celled life forms and are structurally different from multicellular life forms known as eukaryotes. Here is a brief listing of the structural differences between the two classes of living organisms.

  • A nucleus is absent from prokaryotes, but is present in eukaryotes. The nuclear membrane is also absent in prokaryotes.
  • The mitochondria (the cell's power house) is only present in eukaryotes.
  • The endoplasmic reticulum, whose surface provides places for ribosomes to attach and synthesize proteins, is absent in prokaryotes.
  • Lysosomes and microtubules are present in only eukaryotes.
  • Golgi apparatus is present in eukaryotes and not prokaryotes.

Hope this helps.
