Flashcards in Ch 12 Deck (44):
1

What are the two different categories of the fungi and give examples of each?

* Unicellular (Ex: Yeast)
* Filamentous (Ex: Mold, Rust, Mushrooms)

2

The filaments of filamentous fungi are called?

Hyphae

3

What type of lifecycle to the filamentous fungi have?

Sexual and asexual life cycles

4

What are the two types of characteristics found among fungal hyphae?

* Septate (Have crossed walls, or septa, dividing the hyphae into cell like units)
* Coenocytic (Lack septa)

5

Name the two different types of hyphae?

* Ariel Hyphae (Produce spore, reproduction)
* Vegetative Hyphae (Obtain Nutrients, most grow below the surface)

6

What is the role or function of hyphae?

Reproduction and nutrition

7

Where do hyphae sprout from?

Spores

8

Filamentous fungi are considered to be and what do they do?

Saprophytic, they obtain their nutrients from mostly dead organic matter that they dissolve with enzymes, they don't ingest.

9

Filamentous fungi are saprophytic, their digestive enzyme's are secreted from what?

Vegetative hyphae

10

Example of a Conidiophore:

Penicillin

11

How do yeast reproduce?

* Budding and fission (They undergo mitosis followed by budding)
* Not binary fission because fission involves mitosis. Binary fission and bacteria doesn't involve mitosis.
* You have to have a nucleus to undergo mitosis.

12

A fungal disease, infection, is called?

Mycosis

13

Arthropods

* Not my groups but can act as a factor is that carry a variety of my groups.
* Transmit a lot of infections disease.
* Eukaryotes

14

Helminths

Flukes
Segmented flat worms
Nematodes (Round worms) -> whip-, pin-, hook-, wiggly-

15

We have ______ in our cell membrane .

Cholesterol

16

What are the metabolism of fungi?

* Most are obligate aerobes.
* Some facultative anaerobes like yeast

17

Superficial cutaneous fungi, those growing on top of the skin, diseases are called?

Tineas

18

What are the two most common types of fungal infection (yeast infection)?

* Tinea
* Candida

19

Algae can be ______ but lack the complexity of plants.

Photosynthetic

20

Brown algae are commonly called?

Kelp

21

A type of aspergillus?

Conidiophore

22

What are the two most common type of genera of unicellular fungi?

* Candida
* Saccharomyces (Used in the fermentation industry)

23

How can a unicellular organism actually penetrate into a mucosa through to the submucosa?

* By a sigsetion of partial buddings to form these long appendiges called "psudohyphae"
* Never budding to completion so you don't produce a offspring that breaks away

24

You have to have a ________ to undergo mitosis.

Nucleus

25

A mother yeast can bud A max of how many times? It can produce how many yeast?

* 24x
* 25 yeast

26

How can a Uni cellular organism actually penetrate into a mucosa through to the submucosa?

* By a sigsetion of partial budding to form these long appendages called pseudohyphae.
* Never budding to completion so you don't produce a offspring that breaks away
* Able to attack and become more invasive so they become no longer superficial, they can penetrate the tissue to a certain shallow depth.

27

Yeast are capable of what type of growth?

Facultative anaerobic growth

28

Vegetative hyphae are involved in ______ and ______

Catabolism
Growth

29

Dimorphism

* Where a fungus can be either Filamentous or unicellular

30

Dimorphism, mold like produce what?

Vegetative and aerial hyphae

31

Dimorphism, yeast like forms reproduce by?

Budding

32

What causes dimorphic fungus to change appearance? Ex.?

* CO2 concentration
* Ex: Mucor indicus

33

Yeast are not fermenting machines, you give them enough oxygen and they survive by what means?

Aerobic respiration, it's when you Cut the oxygen supply that they switch to a fermentative pathway

34

As CO2 concentration in dimorphism goes up?

They go to a filamentous morphology

35

Flabis

Produce aphlatoxin on peanuts

36

Aspergillus niger

Form nasty fungal balls if it grows inside the lungs

37

Cleviseps perpena

Grow on grains
Produce a toxin that gives you a hallucination high like LSD

38

Ringworm is a _____ infection

Fungal

39

Systemic fungal infection can be life threatening and get into your?

Central Nervous System

40

Most common cutaneous infection are superficial:

Ringworm
Tinea Capitis
Tinea pedis (Athletes Foot)
Tinea cruris

41

What type of infection does Candida cause?

Candidiasis
Ex: Mucocutaneous candidiasis
Vulvovaginal candidiasis (Thrush)
Oropharyngeal
Rectoanal

42

Cryphonectria parasitica

Killed almost every chestnut tree

43

Ceratocystis ulmi

* Carried by bark beetles that wiped the elm population.
* Dutch elm disease.

44

Algae

I. Multicellular
II. Unicellular
III. Diatoms
IV. Dinoflagellates
V. Water Molds
