Question 10

What is artificial classification?

Answer 10

Classification/ grouping based on few easily identifiable characteristics

Question 11

What is natural classification?

Answer 11

Grouping with more evidence based on research into various aspects (such as genetics,biochemistry)

Question 12

What is Phylogenetic classification?

Answer 12

Grouping based on evolutionary development and diversification of a specie

Question 13

What is Phenetic Classification?

Answer 13

Grouping based on observable characteristics (morphological, cytological and biochemical) of of an organism. Used where no fossil records exist to establish evolutionary relationships

Question 14

What are the two main types of classification?

Answer 14

Artificial

Natural

Question 15

What are keys?

Answer 15

Clues used for specimen identification.

Observable characters of unknown organisms are first identified and listed before being matched with diagnostic characters of an existing group

Question 16

What are the Phylums/ Divisions in the traditional classification of Kingdom Plantae?

Answer 16

• Schizomycophytae

• Thallophytae

• Bryophytae

• Pteridophytae

• Spermatophyta

Question 17

Which plants are the first to survive on land?

Answer 17

Bryophytes

Question 18

Between the gametophyte a d sporophyte structure in Rhizopus, which is more dominant? Why?

Answer 18

The gametophyte is the dominant and sporophyte part depends on it for reproduction.

They later become independent
