MMM Exam1

Reproduction

________ is through production of sexual or asexual spores produced on hyphae or on a fruiting body.

Absorption

________: where fungi obtain nutrients by secreting enzymes outside the hyphae.

Virulence

________: Degree or measure of pathogenicity; relative capacity to cause disease.

Cellulose

________: what makes up plant cell walls.

Chitin

________: what makes up fungal cell walls.

Mushroom

Pinning: ________ initials develop from rhizomorphs.

Polycyclic

________: fungi that complete several disease cycle /generations during 1 growing season.

emergence

Damping- off: death of a seedling before or shortly after ________.

Basidiomycota

________: phylum containing mushrooms, rusts & smuts.

Sign

________: structures or products of a pathogen on or in diseases plants.

Pathogen

________: An organism that causes disease.

cycle generation

Monocyclic: fungi complete 1 disease ________ per season.

Pathogenicity

________: The ability of a pathogen to interfere with one or more plant functions.

Symptom

________: result of infection (discolored leaves)

Phase

________ I composting: Making the compost; raw ingredients are mixed, piles are formed and aerobic fermentation takes place.

2 Oomycota characteristics that differentiate them from normal fungi

Cellulose and non-septate hyphae

Hierarchy

Kingdom, Phylum, Class, Order, Family, Genus, Species

Scientific Name

(italics) Genus species

Heterotrophic

cannot photosynthesize

Absorption

where fungi obtain nutrients by secreting enzymes outside the hyphae

Chitin
