Classification

Question 1

What is classification?

Answer 1

Classification is the method used by scientists to order living organisms. All species have a unique classification that results in a binomial name.

Question 2

What is the classification system?

Answer 2

The millions of types of living things can be organised into categorises, where we group together organisms with similar features.

Question 3

How many kingdoms are there and what are they called?

Answer 3

There are 5 animal kingdoms, based upon what an organisms cells are like:

• Animalia (all multicellular animals)
• Plantae (all green plants)
• Fungi (moulds, mushrooms, yeast)
• Prokaryotae (bacteria, blue-green algae)
• Protoctista (Amoeba, Paramecium)

Question 4

There are several further ranks before we reach a particular species. In order, what are they?

Answer 4

• Kingdom
• Phylum
• Class
• Order
• Family
• Genus
• Species

Question 5

Why is binomial classification important?

Answer 5

It is important because it can clearly identify species, study and conserve species and target conservation efforts.

Question 6

Is it easy or difficult to classify a certain organism?

Answer 6

It can be difficult to classify a certain organism.

Question 7

Why don’t scientists classify a virus as a living thing?

Answer 7

Virus’ don’t show all seven processes for life also when it enters a cell it changes the way a cell works so it can make copies of the virus.

Question 8

What are vertebrates?

Answer 8

Vertebrates are animals with a backbone.

Question 9

In order, what are the five kingdoms?

Answer 9

Animalia
Plantae
Fungi
Protocista
Prokaryotes

Question 10

What are the characteristics of animalia?

Answer 10

Multicellular, no cell wall or chlorophyll, heterotrophic feeders e.g all multicellular animals including jellyfish, worms, fish etc

Question 11

What are the characteristics of plantae?

Answer 11

Multicellular, have cell walls and chlorophyll, autotrophic feeders e.g all green plants including algae and mosses (plants that do not produce seeds), conifers and flowering plants (plants that do produce seeds).

Question 12

What are the characteristics of fungi?

Answer 12

Multicellular, have cell walls, don’t have chlorophyll, saprophyll feeders e.g moulds, mushrooms, yeast etc

Question 13

What are the characteristics of protoctista?

Answer 13

Usually unicellular, with a nucleus e.g amoeba. Examples: amoeba and paramecium.

Question 14

What are the characteristics of prokaryotes?

Answer 14

Unicellular, with no nucleus e.g bacteria. Examples: bacteria and blue-green algae.

Question 15

What are phylum (rank) /chordates (classification)?

Answer 15

Animals with a supporting rod running the length of the body e.g backbone

Question 16

What are class (rank) /mammals (classification)?

Answer 16

Animals that are warm-blooded, have lungs and body hair, produce milk and give birth to live young

Question 17

What are order (rank) /primates (classification)?

Answer 17

Ape-like animals

Question 18

What are family (rank)/hominids(classification)?

Answer 18

Human-like animals

Question 19

What are genus (rank) / homo (classification)?

Answer 19

Humans

Question 20

What are species (rank) / sapiens (classification)?

Answer 20

Modern humans

Question 21

What do organisms of the same species have in common?

Answer 21

• Have more characteristics in common than they do with organisms or a different species.
• Can interbreed to produce fertile offspring
