Fungi Flashcards
What are four characteristics shared by fungi?

Chemoorganoheterotrophs
Reproduces sexually and asexually
Cell walls

Hydrolytic
Most fungi in the environment are considered to be what?
Saprophytes
What are some practical uses of fungi for people?
They can be used in antibiotics such as cyclosporin
(T/F) Some fungi can be pathogenic

Different
Via pheromone recognition
