A prokaryotic cell is a unicellular microorganisms that lacks the nucleus and other membrane bound organelles such as mitochondria. This type of cell is classified into two domains called the bacteria and archaea which are also great examples of a prokaryotic cell. To distinguish a prokaryotic cell and a eukaryotic cell you would have to look at the nucleus because a prokaryotic cell does not contain a nucleus but a eukaryotic cell does contain a nucleus. Also a prokaryotic cell is less complex because of the lack of the organelles while eukaryotic cells are more complex because of the number of organelles it has and the functions they have to do in order for the cell to function. As well the size is another way to distinguish the two cells since the singled cell microorganism is much smaller than a multicellular cell. From their fossils dates’ prokaryotic cell are said to have lived almost 3.5 billion years ago.
This picture represents all the parts of a prokaryotic cell. It shows how the cell parts are structured. It demonstrates what a prokaryotic cell holds inside and what it is called. It shows how the singled cell microorganism is shaped. It reveals that outside of the cell has hair-like substances are sticking out.
WORDS:
- Cytoplasm- is a jelly-liked substance that fills the entire cell and holds the organelles in their place.
- Ribosome- organelle that makes proteins and roam around the cell or stay at the rough endoplasmic reticulum.
- Flagella- whip-like structure on cells that is used for movements.
- Plasmid- small DNA molecule that is distinct from a cells chromosomal DNA and is most located in a prokaryotic cell.
- Plasma Membrane- structure that surrounds the cell, gives it protection, and controls what goes in and out of the cell.
- Cell Wall- rigid structure that gives shape to the cell and protects it from infections.
