Success Criteria
Your learning has been successful if you can do the following:

I can describe how bacteria carry out reproduction.
To be able to describe and give reasons for the stages in a bacterial growth curve.

Vocabulary
Learn these so you can communicate this concept well.
Bacterium: The plural of bacteria.
Function: What a structure in a living thing does.
Binary fission: Bacteria make a copy of their cell contents and then split into two cells, identical to the original cell.
Toxins: Substances like CO2 (and sulphites, nitrites, ammonia and…) that at high enough levels cause cell death.
Heterotroph: Organism that can not make their own food – they must consume other things to gain nutrients and energy.
Respiration: The breaking down of glucose to release energy the cell can use to carry out life processes.
