variety of living organisms
5 kingdoms
animals
bacteria
plants
protocists
fungi
Viruses aren't living organisms
don't follow MRS C GREN
10-100x smaller than prokaryotes
they have a protein coat on the outside with genetic material inside
can only reproduce inside living cells
known as parasites - depend on another organism to grow and reproduce
all viruses can be thought of as pathogens - influenza virus, covid 19 etc
animals, plants, fungi and protoctists
eukaryotes
in eukaryotic cells
has DNA in the form of chromosones
have a nucleus
bacteria
prokaryotes
in prokaryotic cells
don't have a nucleus
DNA is loose in the cell
10-100x smaller than eukaryotes
single celled organisms that are just about everywhere
no chloroplasts
most feed off other organisms
some species can photosinthesise
a few can cause disease
like salmonella
most don't have anything to do with humans; many are helpful to help us digest our food.
animals
multicellular
heterotrophs
most reproduce sexually
plants
autotrophs
multicellular
autotrophs - get energy from the Sun in Photosynthesis
heterotrophs - animals get their energy from other organisms
saprotrophs - most fungi feed using saprophytic nutrion
break down the food
absorb all the nutrients
secrete digestive enzymes onto food outside their body
fungi
can't photosynthesis
some are unicellular e.g. yeast
some are multicellular e.g. mushrooms or mould
saprotrophs and heterotrophs
some of the multicellular fungi have a mycelium body made up of hyphae
protoctists
nearly all of them are unicellular
things like chlorella and euglena contain chloroplasts and can photosynthesise
however things like amoeba have to consume other organisms to get energy
most protoctists have nothing to do with humans
things like plasmodium count as a pathogen as it causes malaria
