Prokaryotic Cells 0.0 / 5 ? BiologyCellular processes and structureInternational BaccalaureateOther Created by: Jodie WebberCreated on: 20-10-13 20:56 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). 8 of 8
