Q

Define flagella

A

Allows propelling through fluids ‘motile’

17
Q

What is an endospore?

A

Are thick walled structures that contain a copy of the chromosome

18
Q

Explain the advantage of endospores

A

Allow bacteria to survive in adverse conditions

19
Q

Define binary fission

A

Cells reproduce via the parent cell splitting into 2 halves, producing 2 new cells

20
Q

Identify the different groups of Eukaryotic microbes

A

Algae
Protozoa
Fungi
Yeasts

21
Q

Describe 2 differences in prokaryotic and eukaryotic cells

A

Prokaryotic: DNA is FREE floating within the cytoplasm
Prokaryotic: DO NOT possess internal membrane

Eukaryotic: DNA is contained WITHIN the nucleus
Eukaryotic: Structures of internal membrane

22
Q

Describe 1 difference in prokaryotic and eukaryotic cells

A

Prokaryotic DO NOT posses internal membrane

Eukaryotic posses structures of internal membrane
