Animalia
A kingdom of organisms: multicellular, no cell wall, heterotrophic, have nucleus in cells.
Plantae
A kingdom of organisms: multicellular, have chlorophyll, have cell walls, autotrophic, photosynthesise, cell have a nucleus.
Fungi
A kingdom of organisms: multicellular, have cell walls, saprophytic, cells have a nucleus.
Protoctista
A kingdom of organisms: usually unicellular, cells have a nucleus.
Prokaryotes
(AKA bacteria) A kingdom of organisms: unicellular, no nucleus.
Species
A group of organisms with similar characteristics, which can successfully interbreed to produce fertile young.
Heterotrophic
Get energy from other organisms
Autotrophic
Makes its own food
Saprophytic
Feeds off dead and decaying matter
Binomial system
The system scientists use to name species, it consists of two latin names: the first is the genus, the second is the species. The genus starts with a capital letter but the species name doesn't.
Ring species
A group of related populations that live in a ring. Neighbouring populations can interbreed to produce fertile offspring, but populations that live firth apart cannot.
Oviparous
Lays eggs
Viviparous
Gives birth to live young
Homeothermic
Keeps its body temperature at a constant level
Poikilothermic
Body temperature varies with the organism's surroundings
Mammals
A class of choredate: has lungs, are viviparous, are homeothermic
Birds
A class of chordate: has lungs, are oviparous, are homeothermic
Fish
A class of chordate: has gills, are mostly oviparous, are mostly poikilothermic
Reptiles
A class of chordate: have lungs, are oviparous, are poikilothermic
Amphibians
A class of chordate: absorb oxygen through their skin, are oviparous, are poikilothermic
