Flashcards in Chapter 3 Deck (22):
1

An example of a Necrotroph/non-obligate parasite is _________

- chestnut blight

2

In ectomycorrhizae the fungus is _______ plant cells

- inside

3

A type of saprotrophic fungi that can be grown on dead stuff are _____________

- cultivated mushrooms

4

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

5

Mutualism

- two organisms of different species in a relationship in which each individual benefits from the activity of the other

6

In a mutualistic __________ relationship it is obligate, it cannot grow fungus by itself without the plant

- endomycorrhizae

7

____________ are nutrient recyclers, provide nutrients for living plants, help create soil, and remove material/debris from environment

- saprotrophs

8

Commensalism

- one organism benefits from association (may obtain nutrients, shelter, support, locomotion), the other is unaffected

9

Two examples of biotroph/obligate parasites are ____________ and ____________

- ectomycorrhizae and rusts

10

The majority of plant pathogens are ____________ and can grow fungus in culture without a host

- nectrotrophs

11

Symbiosis

- the interaction of two or more unlike organisms in close proximity, often over a long period of time

12

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

13

There is a mutualistic relationship between _________ and _______

- fungi (myco)
- plant roots (rhizae)

14

Why do your plants need mycorrhizae fungi?

- they are beneficial and form a symbiotic relationship with plant roots

15

Two major types of a mutualistic relationship with Mycorrhizae

1. Ectomycorrhizae
2. Endomycorrhizae

16

Saprotroph

- organism that uses dead organic material for food

17

Biotroph/obligate parasites

- organisms that can live and multiply only on another living organism

18

Parasitism

- one organism benefits at the expense of the other

19

In a mutualistic ___________ relationship it is not obligate, can grow fungus by itself

- ectomycorrhizae

20

___________ refers to mushrooms that are not cultivated, because they are mycorrhizal

- wild mushrooms

21

_________ are obligate fungal parasites that require one or two hosts to live and multiply, obligate(can not grow by itself)

- rusts

22

Types of symbiosis

1. Parasitism
2. Mutualism
3. Commensalism
