What are the five kingdoms?
Plants, animals, fungi, protoctists, prokaryotes
1 of 35
What are autotrophs?
Make their own food
2 of 35
How is something classified as a plant?
Contain chlorophyll, autotrophs, multicellular and rigid cell walls.
3 of 35
What are heterotrophs?
Can't make their own food, have to find it.
4 of 35
How is something classified as an animal?
Heterotrophs, multicellular, no cell wall, no chlorophyll.
5 of 35
What are saprophytes?
They feed off dead organisms and decaying material.
6 of 35
How is something classified as fungi?
saprophytes, multicellular, cell wall, no chlorophyll.
7 of 35
How is something classified as protoctists?
Unicellular, nucleus
8 of 35

Unicellular, no nucleus
9 of 35
What are all the classifications that kindoms split into?
Kingdom, Phylum, Class, Order, Family, Genus, Species
10 of 35
What is the binomial system?
Genus and Species
11 of 35
Why is classifying species important to scientists?
They can accurately identify species where ever they are and there is no confusion,
12 of 35
Why is the binomial system important? (3)
Clearly identifies species, Study and conserve species, Target conservation efforts.
13 of 35
What is a species?
A group of organisms that can interbreed to produce offspring that are fertile.
14 of 35
What is an organism that is difficult to put in a kingdom and why?
Euglena, It has chloroplasts like a plant, It has no cell wall like an animal, It has a flagellum to swim with like bacteria.
15 of 35
What are virus classified as?
They aren't classified as a living thing.
16 of 35
Why do they not classify viruses? (2)
It does not show all seven life processes, When it enters a cell it changes the way the cell works and makes copies.
17 of 35
What are vertebrates?
They have a supporting rod that runs the length of their bodies (backbone).
18 of 35
What is something called if it doesn't have a backbone?
Invertebrates.
19 of 35
What are the groups of vertebrates? (5)
Reptiles, Amphibians, Fish, Birds, Mammals

What does oviparous mean?
Lays eggs.
21 of 35
What does viviparous mean?
Gives birth to live young.
22 of 35
What does hoeotherms mean?
Regulates their own body temperature.
23 of 35
What are Poikilotherms?
Body temperature changes depending on the temperature of the surroundings.
24 of 35
What ways are vertebrates classified? (3)
The way oxygen is absorbed, Reproduction, Thermo-regulation.
25 of 35
What are the features of Reptiles? (4)
Lungs, internal fertilisation, Oviparous, Poikilotherm.
26 of 35
What are the features of Amphibians?
Adults have lungs Larvae have gills, External fertilisation, Oviparous, Poikilotherm.
27 of 35
What are the features of Fish?
Have gills, External fertilisation, Oviparous, Poikilotherm.
28 of 35
What are the features of Birds?
Have lungs, Internal fertilisation, Oviparous, Homeotherm.
29 of 35
What are the features of mammals?
Have lungs, Internal fertilisation, Viviparous, Homeotherm.
30 of 35
What is an example of fitting all vertebrates into these groups?
Sharks, they are fish but they use internal fertilisation and give birth to live young.
31 of 35
How can classification be complicated? (3)
Variation within species, Hybridisation, Ring Species.
32 of 35
What is a hybrid?
The offspring of two closely related species that has characters of both (often infertile).
33 of 35
What is a Ring Species?
Neighbouring populations of species may have slightly different characteristics but can still interbreed as part of a chain.The two ends of the chain can't interbreed.
34 of 35
What is a key?
It is used to help identify a species. They can either be branching or a series of paired statements about the physical characteristics.
