Flashcards in 4.2 kingdoms & classifications Deck (30):
1

traditionally what 2 groups were all living things grouped into?

plants and animals

2

what became apparent regarding the 2 groups as living things were studied in greater detail?

not all organism fit as plants or animals

3

what are the 5 kingdoms?

Prokaryotae
Protoctista
Fungi
Plantae
Animalia

4

what type of organisms are prokaryotae?

bacteria

5

what type of organisms are protoctista?

unicellular eukaryotes

6

what type of organisms are fungi?

yeast
moulds
mushrooms

7

what type of organisms are plantae?

plants

8

what type of organisms are animalia?

animals

9

what are some features of prokaryotes?

unicellular
no nucleus
no visible feeding mechanism

10

what are some features of protoctista?

eukaryotes
unicellular
nucleus
chloroplasts

11

what are some features of fungi?

heterotrophic eukaryotes
rigid chitin cell wall
multi nucleated cytoplasm

12

what are some features of plantae?

multicellular eukaryotes
photosynthetic
cellulose cell wall
autotrophic nutrition (make own food)

13

what are some features of animalia?

heterotrophic
multicellular eukaryotes
heterotrophic nutrition
fertilised eggs

14

prior to classification systems what were organism named according to? (Example)

physical characteristics
e.g. black bird

15

why was it not useful to classify organisms based upon physical characteristics?

animals could have multiple names which could differ according to languages

16

names based on physical characteristics also fail to provide what information?

info about the evolutionary relationships between animals

17

what did Swedish Botanist Carl Linnaeus develop?

the binominal naming system

18

what are the 8 classifications in the naming system?

domain
kingdom
phylum
class
order
family
genus
species

19

how are humans classified?

D - eukarya
K - Animalia
P - Chordata
C - mammalia
O - primates
F - Hominidae
G - homo
S - sapiens

20

why did Linnaeus create the binominal naming system?

so scientists everywhere could use the same names

21

in the binominal naming system no two species have what?

the same name

22

what is the first name in binominal classification?

the generic name

23

what does the generic name tell us?

the genus to which the organism belongs

24

what is the second name in binominal classification?

the specific name

25

what does the specific name indicate?

the organisms species

26

how are names written?

lowercase italics with the first letter of the genus name uppercase

27

what is the binominal name of a dog?

canis familaris

28

why do scientists classify animals?

to identify species
to predict characteristics
find evolutionary links

29

what is the smallest unit of classification?

species

30

what is a species?

a group of organisms that are able to reproduce to produce fertile offspring
