Molds (multi, filamentous)
Mushrooms (multi, filamentous)
Fungi. Eukaryotic or Prokaryotic?
Eukaryotic
Fungi. Unicellular or Multicellular?
Most are filamentous
Some are unicellular
Fungi cell walls
Rigid and contain chitin
Fungi reproduction
Both sexual and asexual
Fungi nutrition
All chemoheterotrophic
Typically saprozoic
Mainly saprobes or decomposers
Fungi environment
Free-living or
Form intimate relationships with other organisms
Fungal morphology
Thallus
Hypha
Mycelium
Body/soma of fungi
Thallus
Tubular filament exhibiting apical growth
Hypha
Mass of hyphae
Mycelium
Types of hyphae based on Septation
Septate hypa
Coenocytic hyphae
Septate hypha is composed of
Cell wall
Pore
Nuclei
Septum
Coenocytic hypha is composed of
Cell wall
Nuclei
Tupes of hypha based on function
Vegetative
Aerial
Reproductive
Hypha that obtains nutrients
Vegetative hypha
Projections above the surface of the medium
Aerial hyphae
An aerial hypha that bear reproductive spore
Reproductive hyphae
Modified hypha that extract nutrients from plants
Haustoria
Specialized branching hypha that exchange nutrients with their plant hosts
Arbuscles
Modified hypha forming hoops
Ring
Root-like structures
Hyphae that grow into bread, anchor the mycelium, and carry out digestion
Rhizoids
Hypha that connects two rhizoids
Horizontal hyphae that exist on the surface of the bread
Stolon
Fungal nutrition
Resistant to osmotic pressue
Grown on very low moisture content
Grow with less nitrogen
Capable of metabolizing complex carbohydrates such as lignin (component of wood)
