37
Q

Name the 8 levels of classification in order.

A 
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
38
Q

What are the 2 major divisions of Plantae?

A

Bryophyte

Tacheophytes

39
Q

Why is classification necessary? (5)

A

Makes communication between scientists more precise and simpler

Provides a quick and accurate description of a particular organism

Assists in identification of an unknown organism

Shows trends in the development within a group

Shows evolution from simple to complex structures

40
Q

What is systemics?

A

the study of the diversity of living things and the relationships of organisms of present day and extinct organisms

41
Q

What is a clade?

A

a group of species that belong to a single branch of the evolutionary tree

42
Q

Define species

A

similar organisms interbreeding to produce fertile offspring

43
Q

What are 2 problems with the definition of species that arise when studying extinct organisms?

A

Fossil are often not the remains of actual organisms

Classifications of extinct organisms can depend upon the no of fossils recovered and if they are fragments or parts of organisms

44
Q

How are modern organisms classified?

A

Using electron microscopy and biochemical techniques to work out detailed cell structure and metabolic processes

45
Q

What is a cladogram?

A

A diagram used to show ancestral relationships between species
