Help yourself to study about the prokaryotic cell by following these free and printable prokaryotic cell diagrams! These cell diagrams are designed to guide you in studying the structures of prokaryotic cell. Follow our diagrams and make sure to save them! Let’s start by discussing in brief about the several parts of prokaryotic cell according to the diagram below.
In the prokaryotic cell diagram above, you can see that a prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. Prokaryotic cells are cells that do not have a true nucleus or most other cell organelles. Organisms that have prokaryotic cells are unicellular and called prokaryotes. Bacteria and archaea are prokaryotes. Prokaryotic cells can be contrasted with eukaryotic cells, which are more complex. Eukaryotic cells have a nucleus surrounded by a nuclear membrane and also have other organelles that perform specific functions in the cell. Prokaryotic cells are usually between 0.1 to 5 micrometers in length (.00001 to .0005 cm). More cell diagrams are provided in the following images.
Like eukaryotic cells, prokaryotic cells have cytoplasm, a gel-like substance that makes up the “filling” of the cell, and a cytoskeleton that holds components of the cell in place. Both prokaryotic cells and eukaryotic cells have ribosomes, which are organelles that produce proteins, and vacuoles, small spaces in cells that store nutrients and help eliminate waste. Some prokaryotic cells have flagella, which are tail-like structures that enable the organism to move around. They may also have pili, small hair-like structures that help bacteria adhere to surfaces and can allow DNA to be transferred between two prokaryotic cells in a process known as conjugation. The capsule is a sticky layer of carbohydrates that helps the bacterium adhere to surfaces in its surroundings.
