Prokaryotic Cells

HideShow resource information
How do prokaryotic cells divide?
Binary fission
1 of 8
What is the role of the cell wall?
A protective layer, preventing external damage or bursting if the pressure gets too high inside.
2 of 8
What does the plasma membrane do?
Responsible for controlling entry and exit of substances, sometimes using active transport.
3 of 8
What is the function of cytoplasm?
Holds the enzymes for catalysing the metabolic reactions, also contains DNA in the nucleoid.
4 of 8
Define pili.
Structures like hairs that stick out from the cell wall and can connect to other bacteria cells to pull together.
5 of 8
What is the job of the flagella?
It is a protein structure that resembles a corkscrew and projects from the cell wall. It turns allowing movement of the cell.
6 of 8
Define ribosomes.
Small granular structures involved in protein synthesis when they translate mRNA.
7 of 8
What does the nucleoid do?
In the cytoplasm and contains naked DNA (the genetic information of the cell).
