General Mycology

Question 1

What are 6 differences between bacteria and fungi?

Answer 1

BacT/Fungi

No mitochondria / Have mictochondrai

Multiply via binary fission (asexual) / Both binary/sexual replication

Typical cell walls w/ petidoglycan, LPS, lipid bilayers / walls contain chitin, chitosan, mannans and glucans, more plant like

Usually do not contain sterols / contain sterols

Susceptible to classical antibiotics / NOT susceptible to classical antibiotics

Question 2

Answer 3

FALSE- they do not contain cholesterols

Question 4

What are the three types of fungi?

Answer 4

saprophytic, symbiotic, parasitic

Question 5

T/F several fungi contain cholrophyll and therefore can manufacture their own food.

Answer 5

FALSE- they lack chlorophyll and can not do these things
