Difference between Bacteria, viruses and fungi
Bacteria
Definition
All bacteria prokaryotes.
Cell type
Unicellular with simple cellular structure.
Number of cell
Unicellular
Size
Range 0.5- 5 micrometre
Cellwall
Made of peptidoglycan under cell membrane present.
Morphology
Cocci
Bacillus
Spiral
PH
Grow best neutral environment. PH; 6.5-7
Mobility
Some Bacteria have motile flagella.
Ribosomes
70s; 50s, 30s
Pilli
Have pilli
Prevention
Infection can be prevented by antibiotic.
Treatment
Antibiotic medicine
Antibiotic work
Yes
Nutrition
Need warmth, moisture nutrient
Rerspiration
Divided into aerobes and anaerobes
Benefit
Can be harmful or useful
Harmful
Cause TB, tetanus, Pneumonia, sore throat, cholera; food poisioning.
For example;
Corynebacteria
Mycobacterium
Bacillus
Clostridium
Virus
Definition
Virus doesn't considered as cell.
Cell type
Don't have cells.
Number of cell
Size
Smaller than bacteria.
Cellwall
Contain protein coat instead cellwall.
Morphology
Filamentous
Enveloped
Head and tail
Cylinderical
PH
Optimum PH 7.1
Mobility
Can't move untill get host cell
Ribosomes
Absent, not present.
Pilli
No pilli present.
Prevention
Prevent by vaccine.
Treatment
Antiviral medication
Antibiotic work
No
Nutrition
Depend on living host
Rerspiration
Non-living
Benefit
Always harmful
Harmful
Cause disease, measles, mumps, HIV, Polio
For example,
Corona virus
Hepatitis virus
Herpes virus
Bacteria can be infected by virus called bacteriophages.
Fungi
Definition
All fungi are eukaryotes.
Cell type
Most fungi are multicellular with complex cellular structure.
Number of cell
Most fungi are multicellular with complex cellular structure.
Size
2 to 10 micrometre
Cellwall
Made of chitin
Morphology
Vary in shape, thread like hyphae budding
PH
Best slightly acidic environment, PH; 4.6
Mobility
Immobile
Ribosomes
80s; 60s, 40s
Pilli
No pilli
Prevention
Prevented by antifungal
Treatment
Antifungal medication
Antibiotic work
No
Nutrition
Need warmth, moisture nutrient
Rerspiration
Areobes or anaerobes
Benefit
Can be harmful and useful.
Use in break making, making bear
Harmful
Cause disease, causes opportunistic infection
Poisonous
Decaying food
For example;
Candida
Aspergillus
