What causes more plant diseases than any other organism?
Fungi/FLO's
Are Fungi and FLO's eukaryotes or prokaryotes?
Eukaryotes
Are Fungi and FLO's autotrophs or heterotrophs? What is the definition of what they are?
Heterotrophs, organisms that lack chlorophyll or other photosynthetic pigments and thus must obtain their nutrients from other external sources. They obtain these nutrients by absorbing them through specialized structures.
What causes more plant diseases than any other organism?
Fungi/FLO's
Are all pathogens parasites or are all parasites pathogens or are both true?
All pathogens are parasites, but not all parasites are pathogens.
Are Fungi and FLO's eukaryotes or prokaryotes?
Eukaryotes
What are the 4 styles of heterotrophic exsistence and describe each one.
Obligate Saprophyte
-only lives off dead and decaying OM
Obligate Parasites
-Only survives if deriving nutrients from living organism
Facultative parasites
-most of the time on dead and decaying OM, but can be parasite
Facultative Saprophyte
-most of the time as a parasite, but can grow n dead and decaying OM
What form does the vegetative stage of growth take in fungi/flo's?
Hyphae
Are Fungi and FLO's autotrophs or heterotrophs? What is the definition of what they are?
Heterotrophs, organisms that lack chlorophyll or other photosynthetic pigments and thus must obtain their nutrients from other external sources. They obtain these nutrients by absorbing them through specialized structures.
What are the 2 forms of hyphae?
Septate - cross walls
Coenocytic (non-septate) - no cross walls
Are all pathogens parasites or are all parasites pathogens or are both true?
All pathogens are parasites, but not all parasites are pathogens.
List motile fungal/flo spores.
Zoospores
What are the 4 styles of heterotrophic exsistence and describe each one.
Obligate Saprophyte
-only lives off dead and decaying OM
Obligate Parasites
-Only survives if deriving nutrients from living organism
Facultative parasites
-most of the time on dead and decaying OM, but can be parasite
Facultative Saprophyte
-most of the time as a parasite, but can grow n dead and decaying OM
List non-motile fungal/flo spores.
Oospores, ascospores, basidiospores, chlamydospores, conidia, and zygospores
What form does the vegetative stage of growth take in fungi/flo's?
Hyphae
What fungal/flo spores are products of sexual reproduction?
Oospores, ascospores, and basidiospores
What are the 2 forms of hyphae?
Septate - cross walls
Coenocytic (non-septate) - no cross walls
What fungal/flo spores are products of asexual reproduction?

Zoospores
What are the 2 reasons Fungi produce spores?
1. Dissemination
