Plant Pathology 401 Midterm 2

Front 1

What causes more plant diseases than any other organism?

Back 1

Fungi/FLO's

Front 2

Are Fungi and FLO's eukaryotes or prokaryotes?

Back 2

Eukaryotes

Front 3

Are Fungi and FLO's autotrophs or heterotrophs? What is the definition of what they are?

Back 3

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.

Front 4

What causes more plant diseases than any other organism?

Back 4

Fungi/FLO's

Front 5

Are all pathogens parasites or are all parasites pathogens or are both true?

Back 5

All pathogens are parasites, but not all parasites are pathogens.

Front 6

Are Fungi and FLO's eukaryotes or prokaryotes?

Back 6

Eukaryotes

Front 7

What are the 4 styles of heterotrophic exsistence and describe each one.

Back 7

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

Front 8

What form does the vegetative stage of growth take in fungi/flo's?

Back 8

Hyphae

Front 9

Are Fungi and FLO's autotrophs or heterotrophs? What is the definition of what they are?

Back 9

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.

Front 10

What are the 2 forms of hyphae?

Back 10

Septate - cross walls
Coenocytic (non-septate) - no cross walls

Front 11

Are all pathogens parasites or are all parasites pathogens or are both true?

Back 11

All pathogens are parasites, but not all parasites are pathogens.
