Q

What do protozoan cysts, fungal spores, bacterial endospores, and bacterial exospores have in common?

A

they are all a means of environmental resistance for survival

17
Q

what purpose does a protozoan cyst serve

A

non-reproductive, short-term means of surviving between hosts

18
Q

what purpose does a fungal spore serve

A

reproductive, resting state, can generate into another individual of the species

19
Q

what purpose do bacterial endospores serve

A

non-reproductive. forms new internal daughter cell, long term means of surviving harsh conditions

20
Q

what purpose do bacterial exospores serve

A

reproductive, less resistant than exospores
