Question 2

Phylogenetics

Answer 2

Taxonomy based on similarity of gene sequence

Question 3

Prokaryotes

Answer 3

Bacteria & Archaea

Question 4

Eukaryotes

Answer 4

Protozoa, algae, and fungi

Question 5

Protozoa

Answer 5

Unicellular

Animal-like in the sense that they obtain nutrients and energy from other organisms

They move via pseudopodia, cilia, flagella

Question 6

Fungi

Answer 6

Molds & Yeasts

Plant-like in that they have cell walls

Animal-like in that they obtain nutrients and energy from other organisms

Question 7

Molds

Answer 7

Grow as long filaments called HYPHAE

multicellular

SPORES allow them to spread and reproduce

Question 8

Yeast

Answer 8

Unicellular

Reproduce via BUDDING

Question 9

ALGAE

Answer 9

Unicellular or multicellular

Plant-like in that they make their own nutrients from energy in the sunlight via photosynthesis

Some are animal-like too

Locomotion via cilia and flagella

Question 10

Bacteria

Answer 10

Unicellular
RODS
COCCI
SPIROCHETES

small size

Simple internal organization

Obtain nutrients and energy from a nearly infinite variety of sources

Question 11

Archaea

Answer 11

Unicellular

Often live in extreme environments

Often have unusual shapes

METHANOGENS

Question 12

Viruses

Answer 12

Not microorganisms

Considered microbes

They do not obtain nutrients and energy in the traditional sense

Have their own RNA and DNAA

Question 13

Organics

Answer 13

Molecules with carbon atoms bound to hydrogen atoms (C-H)
