An organism that obtains food from decaying matter
What’s a fungi relative?

What is the thallus?
The body of the fungus
What is the mycelium?
A densely branched network of the hyphae of a fungus
What is the hyphae?

What is a septa?
The cells that make up hyphae are divided by these cross sections
What does coenocytic mean?
Multinucleated
What are fungi cell walls composed of?
Chitin
What are zygomycotas?
Saprotrophs including bread molds. They produce zygospore.
What are ascomycotas?
Mostly saprotrophs, includes morels, truffles, powdery milder, ergo, chestnut blight, aspergillus, and candida. They produce an ascus (fingerlike sac during sexual reproduction).

Toadstools, mushrooms, bracket fungi, puffballs, stinkhorns, smuts and rusts. Produce basidia in their mushroom.
What are glomeromycotas?
Also known as arbuscular mycorrhizae. Form a symbiotic relationship with plant roots, entering the cells of the root.
What are ecotomycorrhizaes?
Mycorrhizae in which the fungal hyphae do not penetrate the root cells of the plant.
What are Chtridiomycotas?
Chytrids, a primitive division of fungi that live in water & produce gametes with flagella. Include significant amphibian parasite.
