Q

Limitation of eukaryotes compared to prokaryotes?

A

limited metabolic diversity, since most are obligate anaerobes and use either photosynthesis or organic compounds for energy

Q

What are fungi

A

Include microbes (yeast) and non-microbes (mushrooms)
Microbial group most closely related to animals
Chitin cell walls

17
Q

What is candida albicans?

A

Opportunistic pathogen commonly found in healthy individuals. Most common cause of yeast infection in women

18
Q

What is a common model yeast?

A

Saccharomyces cerevisiae

19
Q

What are some common uses of yeast?

A

Coversion of carbs to CO2 and alcohol via fermentation, baking

20
Q

What are amoeba

A

Single-celled eukaryotes that inhabt freshwater and soil

21
Q

What are amoebazoa?

A

Diverse phylum of eukaryotes

22
Q

What do amoeba use for locomotion, how do they work

A

Pseudopods
Temporary projections that stick out, “crawl” across surfaces

23
Q

What is a protist

A

Historical term used for euk that is not a plant, animal or fungus. Doesn’t actually refer to a specific group. One of the old kingdoms of life (outdated)

24
Q

What is plankton

A

“drifters” diverse (not just microbes, not just euk)
