five kingdoms and three domains Flashcards
what are the five kingdoms
animals
plants
fungi
prokaryotes
protists
features of animals
multicellular
cells have nuclei
no cell walls
features of plants
multicellular
cells have nuclei and chloroplasts
make own food
cell walls
features of fungi
multicellular (exc. yeast)
cells have nuclei
chitin cell walls
feed off dead matter
feature or protists (eg. algae, amoeba)
mostly unicellular
cells have nuclei
some have cell walls (not chitin)
features of prokaryotes
unicellular
no nucleus
flexible cell wall
what is used to name organisms
binomial naming system based on genus and species
why was the three domain system introduced
developments in science - microscopes and biochemistry
this found that some species were more distantly related than first thought
what is the domain bacteria
cells with no nucleus
circular dna in cytoplasm
no unused sections of DNA in genes
TRUE BACTERIA
what is the domain archea
cells with no nucleus
circular DNA in cytoplasm
unused section of DNA in genes
live in extreme environments such as hot springs
what is the domain eukaryota
cells with nucleus
unused sections of DNA in genes
organisms with nucleus enclosed in membrane
