Bacteria vs.
Virus
Similarities Differences
·
Have enzymes
|
·
Bacteria are
prokaryotic cells
|
·
Both cause diseases(Pathogens)
|
·
Viruses are non-cellular
|
·
Do not have
nucleus
|
·
Bacteria are spherical,
rod, or spiral shaped.
|
·
Can survive
extreme weather conditions
|
·
Virus are
geometric shape
|
·
Bacteria:
Reproduction
|
|
·
Virus:
Replication
|
|
·
Bacteria: can
multiply on non-living surfaces
|
|
·
Virus: must
have a living host to multiply
|
Virus vs.
Prion
Similarities Differences
·
Contain proteins
|
·
Prions: do not
have nucleic acid in cell structure
|
·
Host can be on
mammals
|
·
Virus: Nucleic
acid to help them reproduce
|
·
Need living
cells to grow and reproduce
|
·
Virus: have
protein coat
|
·
Are non-living
things
|
·
Prions: cause
brain diseases only
|
·
Virus: produces
many severe diseases
|
Bacteria vs.
Protist
Similarities Differences
·
Fusion of
gametes
|
·
Protist: have membrane
bound-nucleus
|
·
Are unicellular
|
·
Protist: Eukaryotic
Cells
|
·
Cause diseases
(pathogens)
|
·
Bacteria: Prokaryotic
Cells
|
·
Divide by
binary fission
|
·
Bacteria have a
cell wall: therefore being spherical, rod, or spiral shaped.
|
·
Heterotrophs or
autotrophs
|
·
Protist lack a
cell wall: therefore can not stay n specific shapes.
