|
Organising living organisms into groups based on how closely related they are to one another.
|
|
|
All living things are divided into FIVE KINGDOMS what are they?
|
Plants, animals, fungi, protoctists and prokaryotes
|
|
|
Plants contain CHLOROPHYLL and are AUTOTROPHS what does this mean?
|
They're able to make their own food by photosynthesis
|
|
|
What properties do plant cells have?
|
They're multicellular and have rigid cell walls
|
|
|
Animals are HETEROTROPHS what does this mean?
|
This means they cannot make their own food so they have to move about and find things to eat.
|
|
|
What properties do animal cells have?
|
Animals are multicellular like plants, but they don't have cell walls or chlorophyll
|
|
|
Fungi are SAPROPHYTES what does this mean?
|
This means they feed off dead organisms and decaying material
|
|
|
What properties do PROTOCTISTS have?
|
They are unicellular (single celled)
They also have a nucleus e.g. algae |
|
|
What properties do PROKARYOTES have?
|
They are unicellular
They don't have a nucleus e.g. bacteria |
|
|
Kingdoms are subdivided into smaller and smaller groups of organisms?
|
Kingdom
Phylum Class Order Family Genus Species |
|
|
What are animals divided into?
|
Vertebrates and Invertebrates
|
|
|
What features do vertebrates have?
|
They have a backbone and an internal skeleton
|
|
|
What features do invertebrates have?
|
They don't have a backbone
Some have an external skeleton |
|
|
What five groups (classes) are vertebrates divided into?
|
Fish, Amphibians, Reptiles, Birds and Mammals
|
|
|
Scientists divide vertebrates on three main things, what are they?
|
How they absorb OXYGEN
How they REPRODUCE How they REGULATE THEIR INTERNAL BODY TEMPERATURE |
|
|
What do you get if a male from one species breeds with a female from a second species?
|
You will get a HYBRID these can be fertile and can be infertile.
|
|
|
What is the Binomial System?
|
The binomial system gives each species a two part Latin name
The first part refers to the Genus and The second part refers to the species |
|
|
How has the binomial system helped scientists?
|
It has helped them to
Identify species Study species Conserve species Target conservation efforts |
|
|
What are keys used for?
|
They are a series of questions to identify creatures
