Q. Other than being prokaryotic, state two ways in
which a typical bacterial cell differs from a typical

Q. Describe how some bacteria respond in order to
survive when environmental conditions become
unfavourable.
A. Produce (endo)spores
Q. To which kingdom does the organism used in
industrial fermentation belong?
A. Fungi
Q. What are antibiotics?
A. Substances produced by micro-organisms that
inhibit growth or reproduction of bacteria or fungi
Q. What are photosynthetic bacteria?
A. Using light to make food or obtain energy
Q. Name two forms of heterotrophic nutrition
found in bacteria.
A. Parasitic and saprophytic
Q. Why are antibiotics not prescribed for a person
suffering from a viral infection?
A. Antibiotics have no effect on viruses
Q. Under what circumstances does a bacterial cell
form an endospore?
A. Harsh unfavourable conditions
