How does the structure of a virus differ from a bacterium
Bacteria= Free living cells with no Nucleus
Virus= Non-living collection of molecules
They need a host to survive
They also have a Nucleus
6 of 24
Bacteria features
No protein coat
All are pathogens
Respire
7 of 24
Fungus features
Cell walls made of chitin
Contain DNA in Nucleus
8 of 24
Virus features
All are pathogens
Contain DNA in Nucleus

Plants
Multicellular
Store carbs as starch or sucrose
Cell walls made of cellulose
19 of 24
Animals
Heterotrophs- Feed on other organisms
Store carbs as Glycogen
20 of 24
Fungi
Some are unicellular
Others have body organised into a mycelium. made of hyphae
Cell walls made of chitin
Saphrotic Nutrition
21 of 24
Protoctists
Single celled
Some such as amoeba have features like an animal cell
Others such as chlorella are more like plant cells
Pathogenic example- Plasmodium- Disease- Malaria
22 of 24
Bacteria
Microscopic Single Celled
Obtain food as parasites or by causing decomposition
CIRCULAR DNA
Examples- Lactobacillus- Rod shaped
Used in production of yogurt from milk
Pneunomococcus- Aerobic
Acts as a pathogen causing pneumonia
23 of 24
Viruses
Tiny particles, smaller than bacteria
Parasitic- Need a host to reproduce
DNA or RNA in Nucleus Coat
