What organelles are expected to be found in eukaryotes but not in prokaryotes?
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.
The orgenelles present in Eukaryotes but not in Prokaryotes are a prominent nucleus , lysosomes ( suicide bags of the cell ) and peroxisomes , endoplasmic reticulum , Mitochondria (power house of the cell ) and Golgi apparatus. Eukaryotes are the most primitive type of organisms.
