Question 1

What is the primary basis of classification in the Linnaean system?

Answer 1

The Linnaean system primarily classifies organisms based on shared physical characteristics and hierarchical ranks.

Question 2

True or False: Cladistic classification focuses on evolutionary relationships.

Answer 2

True

Question 3

Fill in the blank: In the Linnaean system, the basic unit of classification is the __________.

Answer 3

species

Question 4

What does the term ‘clade’ refer to in cladistics?

Answer 4

A clade refers to a group of organisms that includes an ancestor and all its descendants.

Question 5

Which classification system uses a branching diagram to represent evolutionary relationships?

Answer 5

Cladistic classification uses a branching diagram known as a cladogram.

Question 6

Multiple Choice: Which of the following is a key feature of the Linnaean system? A) Use of molecular data B) Hierarchical structure C) Focus on genetic relationships

Answer 6

B) Hierarchical structure

Question 7

What is the significance of monophyletic groups in cladistics?

Answer 7

Monophyletic groups are significant in cladistics because they include an ancestor and all its descendants, indicating true evolutionary relationships.

Question 8

True or False: The Linnaean system can accommodate newly discovered species easily.

Answer 8

False

Question 9

What is one limitation of the Linnaean classification system?

Answer 9

One limitation is that it does not always reflect the evolutionary history or relationships among organisms.

Question 10

Fill in the blank: Cladistics relies heavily on __________ data to determine relationships.

Answer 10

phylogenetic
