prokaryotic cell structure

How to prokaryotic cells typically compare to eukaryotic

.Smaller

.simpler

.no membrane bound organelles

Most common prokaryotic example

Bacteria

What is located at a

Plasma membrane

What is the plasma membrane made of and what is its role

Made of proteins and Lipids- controls movement of substances in and out

What is located at b

Cytoplasm

What is the cytoplasm of prokaryotes like

Contains no membrane bound organelles and the ribosomes it does have are much smaller than those in Eukaryotes

What is located at c

Flagella

What is the flagella

Long hair like structure that rotates to make the cell move, not all prokaryotes have them but some have multiple

What is located at d

The circular DNA

Prokaryotes have no nucleus so how is dna present

DNA float free in thr cytoplasm and the circular DNA is present as a long coild up strand not attached to any histone proteins

What is located at d

Plasmids

What are plasmids

Small loops of DNA that are not part of the main DNA molecule some prokaryotes have none others have multiple, they contain the genes for things like antibiotic resistance and can be passed between prokaryotes

What is located at e and why is it there

A capsule made of a secreted slime which some prokaryotes have such as the one that bacteria has to help prevent Attack by cells in the immune system

What is located at f

Cell wall

Use of cell wall

Supports cell and prevents changing shape
