CLASSIFICATION

Question 1

What kingdom is under the bacteria domain? (1)

Answer 1

Eubacteria

Question 2

what is the phylogenetic species concept? (1)

Answer 2

defines a species by its evolutionary lineage where two lines diverge sufficiently they are called separate species.

Question 3

what kingdom is under the archea domain? (1)

Answer 3

archae bacteria

Question 4

who proposed the three domain model? (1)

Answer 4

Carl Woese in 1990 who suggested a classification system based on RNA.

Question 5

what kingdom are under the Eukarya domain? (4)

Answer 5

-protista
-plantae
-fungi
-animalia

Question 6

what is a disadvantage for the biological species concept? (2)

Answer 6

-does not take into account geographical separation
-only applies to organisms that reproduce sexually

Question 7

what is the biological species concept? (2)

Answer 7

the concept is the most common definition of species. it defines a species as a set of individuals who can reproduce to produce a fertile offspring.

Question 8

what is a disadvantage of the phylogenetic species concept? (1)

Answer 8

deciding what constitutes sufficient divergence can be a problem.

Question 9

what is the three domain model? (1)

Answer 9

separates prokaryotes from the archea domain, e.g eukaryotes, archea and prokaryotes (bacteria)

Question 10

what are the key differences in structure in the 3 domains? (3)

Answer 10

eukarya;
-ribosome: 80s
enzymes: RNA - 12 proteins

bacteria;
-ribsome: 70s
enzymes: RNA - 5 proteins

archea:
-ribosome: 70s
enzymes: RNA - 8-12 proteins

Question 11

what are some characteristics of the fungal kingdom? (5)

Answer 11

-has a cell wall made of chitin
-are heterotrophic
-most are multicellular (yeast exception)
-reproduce via sporation
-have structures called mycellium

Question 12

what are some characteristics of the protozoa kingdom? (4)

Answer 12

-mainly single celled or a few cells (cells are not specialised)
-resemble other kingdoms
-protophya resemble plants
-protoza resemble animals

Question 13

what are some characteristics of the animal kingdom? (4)

Answer 13

-sexual reproduction
-animal cells (dont have a cell wall)
-are motile (except animals such as coral)
-are multicellular heterotrophs

Question 14

what is the protozoa kingdom? (1)

Answer 14

a group of eukaryotic organisms that do not fit into other kingdoms

2) kingdom
3) phylum
4) class
5) family
6) genus
7) species

Question 17

what is a eukaryote? (1)

Answer 17

has a membrane bound nucleus (true nucleus)

Question 18

what are the characteristic of the plant kingdom? (4)

Answer 18

-non motile
-made up of plant cells (have cellulose cell wall)
-they are autotrophs
-mostly multi-cellular - except plants like moss

Question 19

what is meant by domain? (1)

Answer 19

the type of cell that organisms are made up of, eukaryotic or prokaryotic

Question 20

what is the binomial name? (1)

Answer 20

the genus and the species of an organism combined

Question 21

what does taxonomy mean? (1)

Answer 21

is a form of classification that focuses on physical similarities between different species, for ease of naming and identification.

Question 22

what does classification mean? (1)

Answer 22

the arrangement of organisms into groups or various sizes on the basis of shared features.

Question 23

what does phylogeny mean? (1)

Answer 23

the classification of organisms by the evolutionary relationship, so that every group shares a common ancestor.

Question 24

what is an autotroph? (1)

Answer 24

an organism that makes its own food (using energy through the sun)
