Different from Ascomycetes because there is a definite lack of sexual reproduction, which is why they are called Imperfect Fungi

Water Molds -- Oomycota

Water Molds -- Oomycota

The water molds are better known as the MILDEWS. Fish tank fuzz is an example.

Protist-like mold because share common characteristics with plant-like protists, such as the cell wall

Things to Know about Oomycete Fungi

Things to Know about Oomycete Fungi

Water molds or mildews

Cause diseases such as potato blight

Cell walls made of cellulose (like plant)

Hyphae have multiple nuclei! Because the cell walls do not fully close off.

Spore swims away like a flagellate, which is why it is protist like (think of Euglena)

Cross Walls of Hyphae

Cross Walls of Hyphae

Coenocytic hyphae where the nucleis of each cell is embedded in the cytoplasm without a cell wall

Eg. Zygomycota, Oomycota

Hyphae with cross walls

Eg. Basidiomycota, Ascomycota

Lichens

Lichens are mutualistic symbiotic organisms. They have an fungus and a _ or cyanobacterial portion. There are three lichen growth forms which are predominant in nature: _

Fruticose

Slide 37

Mycorrhizae

Mycorrhizae

Mycorrhizae means fungus-root; mutualistic relationship between plant and fungi

The plant photosynthesizes while the fungus more efficiently takes up nutrients and water from the rhizosphere than the roots would alone.

Plant benefits include:

Improved nutrient/water uptake

Improved root growth

Improved plant growth and yield

Improved disease resistance

Reduced transplant shock

Reduced drought stress
