Why do we need to classify organism ?
1) to identify species using a clearly defined system
2) to predict characteristics
3) to find evolution are links and find common ancestors
4) to provide universally recognized system
A - level definition of Species ?
A group of living organism consisting of similar individuals capable of interbreeding to produce fertile offspring
What are the rules of naming a species ?
First name : name of genus of the organism belongs to
→ Written in caps letter
Second name : name of the species the organism belong to
→ written in a lower cap
The 2 names are underlined when hand written or are in italics when edi
What are the 5 Kingdoms ?
prokaryotae
Protoctista
Fungi
Plantae
Animalia
Features of Pokaryotae
Unicellular
No nucleus or membrane bound organelles
Small ribosomes
No viable feeding mechanisms
Cell walls
What are some examples of prokaryotae
Bacillus anthracis
Staphylococcus aureus
Escherichial coil
What are the features of protoctista
Mainly unicellular
Have a nuclei
Have membrane bond organelle
Contain chloroplasts
Can be autotrophs on heletotrophs
What the some examples of protoctista
Paramecium
Amoeba
Slime moulds
What are the features of animalia
Multicellular
Nucleus + membrane bound organelles
Can move
Heterotropgs
No chloroplasts
What are some examples of animalia
Cats, worms, sponges
What are the features of fungi
Uni or multicellular
Nuclei+ membrane bound organelles
Cell wall made of chitin
Not able to move
Nutrients absorbed from decaying matter
Whet are some examples of fungi
Mushrooms, moulds. , yeast
What are some features of plantae
Muticellular
Nucleus + membrane bound organelles
Don't move
Contain chlorophyll
Autotrophs
What are some example of plantae
Roses, trees, grasses
What on the top level of classification + the 3 domain
Bacteria → eubacteria
Archaea → archaebacteria
Eukary → protectista or plantae or fungi …
