16
Q

Phylogenetic Tree

A

a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.

17
Q

Homologous Structure

A

similar physical features in organisms that share a common ancestor, but the features serve completely different functions.

18
Q

Prokaryotic Cell

A

no membrane bound organelles

19
Q

Eukaryotic Cell

A

membrane bound organelles

20
Q

Dichotomous Key

A

ask yes or no questions to classify a newly discovered organism compared to existing organisms

21
Q

Autotroph

A

produces its own food
can either be photosynthetic or chemosynthetic

22
Q

Heterotroph

A

eats other organisms to get energy

23
Q

natural selection

A

the process through which populations of living organisms adapt and change.

24
Q

Artificial Selection

A

the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations

25
How to classify species
dichotomous keys
26
The correct format for writing out the name of an organism
both Genus and species are italicized or underlined Genus is capitalized, species is lower case
27
Anatomical evidence
do structures of the organisms look the same
28
Physiological evidence
do the proteins and enzymes in the cell work the same
29
Genetic evidence
how genetically closely related are the genes and the proteins they make
30
what are the 6 kingdoms
1.Bacteria 2. Archaea 3. Protista 4.Plantae 5. Fungi 6. Animalia
31
how did the 6 kingdoms come to be
Swedish botanist Carolus Linnaeus in the 1700s
32
similarities between Eukaryotes and Prokaryotes
33
differences between Eukaryotes and Prokaryotes
eukaryotes have membrane bound organelles prokaryotes are 1/10th the size of eukaryotic cells
34
general characteristics bacteria
Prokaryote, unicellular, cell wall made of peptidoglycan, Autotrophs and heterotrophs, Asexual
35
general characteristics archaea
Prokaryote , unicellular, polysaccharides, autotrophs and heterotrophs , Asexual
36
general characteristics Protista
Eukaryote, uni or multicellular, cell wall idk, autotrophs, Asexual and sexual
37
general characteristics plantae

38
general characteristics fungi
eukaryote, mostly multicellular, cell wall chitin, heterotrophs, Sexual
39
general characteristics animalia
eukaryote, multicellular, no cell wall, heterotrophs, sexual
