Classification
- Grouping things by their features or characteristics
- The more characteristics that are used to group similar organisms together, the more reliable is the classification
Kingdom - Group of similar phyla e.g. Anamalia
Phylum - Group of similar classes e.g. Chordata
Class - Group of similar orders e.g. Mammalia
Order - Group of similar families e.g. Carnivora
Family - Group of similar genera e.g. Canidae (dog family)
Genus - Group of similar species
Species - Organisms that have most characteristics in common e.g. Canis lupus
Five kingdoms of organisms
1) Anamalia (animals):
- Multicellular
- No cell walls
- No chlorophyll in cells
- Feed
- heterotrophically (eat other organisms)
2) Plantae (plants):
- Multicellular
- Have cell walls
- Have chlorophyll
- Feed autotrophically (make own food)
3) Fungi
- Multicellular
- Have cell walls
- No chlorophyll
- Feed saprophytically (digest food outside the body)
4) Protoctista
- Mostly unicellular (body is a single cell)
- nucleus in cell
5) Prokaryotae
- Unicellular
- No nucleus in cell
That's the end of today's topic!
