Features Bacteria Protoctist Fungi Plants Animals Virus

Nucleus

No, instead of a nucleus it has

nuceloid (circular piece of DNA)

Yes, but has more than one Yes

Yes YesNo, instead it has a strand

ofDNA or RNA

NutritionConsume dead things and

decompose shed skin/leaves

(Saprotrophs)

Autotrophs: (make foodusing photosynthesis)

Heterotrops: (consumesorganic matters)

They eat dead organisms(Hyphae, release the roots

and absorbs the deadnutrients)

Plants uses sun and waterto get their energy

Therefore, they requiresugar

and minerals

Herbivore, Carnivore,Omnivore

Virus doesn't eat, but hijacks

other living cells andduplicates itself

Cell wallIt has got something

similar:a cell wall that does not

contain cellulose

Yes Yes, it has a cell wallmade out of chitin

Yes, it has a cell wall madeout of cellulose

No, it doesn't have a cell wall

No, but instead of a cell wall

it has a protein coat

Size

Very small, 1-2 micrometers

Only visible by microscope

Largest is only 1mmFungi can be big as a foot, but the roots can be as

big asa football pitch

It can be any size It can be any size

Similar size to bacteria

Pathogen Some Some(Malaria, etc.)

Some None None All
