Chapter 3 Flashcards
An example of a Necrotroph/non-obligate parasite is _________
- chestnut blight
In ectomycorrhizae the fungus is _______ plant cells
- inside
A type of saprotrophic fungi that can be grown on dead stuff are _____________
- cultivated mushrooms
In ectomycorrhizae and endomycorrhizae carbon(sugars) flow from _______ to __________, fungus absorbs _________ and ______ and moves to plant, ________ surface area, the fungus protects the roots
- plant to fungus
- nutrients and water
- increases
Mutualism
- two organisms of different species in a relationship in which each individual benefits from the activity of the other
In a mutualistic __________ relationship it is obligate, it cannot grow fungus by itself without the plant
- endomycorrhizae
____________ are nutrient recyclers, provide nutrients for living plants, help create soil, and remove material/debris from environment
- saprotrophs
Commensalism
- one organism benefits from association (may obtain nutrients, shelter, support, locomotion), the other is unaffected
Two examples of biotroph/obligate parasites are ____________ and ____________
- ectomycorrhizae and rusts
The majority of plant pathogens are ____________ and can grow fungus in culture without a host
- nectrotrophs
Symbiosis
- the interaction of two or more unlike organisms in close proximity, often over a long period of time
Necrotroph/non-obligate parasites
- parasitic fungi that derive their nutrients and energy from dead cells of other organisms (the hosts)
- does not require another living organism to live and multiply
There is a mutualistic relationship between _________ and _______
- fungi (myco)
- plant roots (rhizae)
Why do your plants need mycorrhizae fungi?
- they are beneficial and form a symbiotic relationship with plant roots
Two major types of a mutualistic relationship with Mycorrhizae
- Ectomycorrhizae
2. Endomycorrhizae
