- thy can be multicellular
2
Q

A
- Yeasts
EXAMPLE:
- Saccharomyces Cerevisiae
3
Q

A
- mushrooms
- molds
4
Q
- List 3 characteristics related to Fungi?
A
- THEY ARE NON-MOTILE
- THEY USUALLY LIVE IN MOIST ENVIRONMENTS
- that are humid
- they can also live in aquatic environments - THEY HAVE AN OPTIMUM GROWTH TEMPERATURE
- of 2 to 20° C
5
Q
- What kind of microorganisms are Fungi?
A
- they are Eukaryotic
6
Q
- What are two different kinds of Fungi?
A
- Heterotrophs
- Saprophytes
7
Q
- What are Heterotrophs?
A
- these are a type of fungi
- they absorb nutrients from their external environment
8
Q
- What are Saprophytes?
A
- these are decomposers
- they obtain their nutrients from dead organic matter
9
Q
- What does this image show?
A
- this is a mushroom
10
Q
- What does this image show?
A
- this is an Ascomycete
11
Q
- What does this image show?
A
- this is multicellular fungus
12
Q
- What does this image show?
A
- this is yeast
13
Q
- What does this image show?
A
- this is mold
14
Q
- What is the Fungal Cell Wall made of?
A
- chitin
15
Q
- What are the body structures of Fungi?
A
- Multicellular Filaments
- Unicellular Fungi
(such as yeasts)
16
Q
- Define Dimorphism (with relation to fungi) ?
A
- this is when some Fungal species can grow both as
filaments or yeasts - this depends on their environmental conditions
EXAMPLE:
- Blastomyces
17
Q
- What kind of colonies do Yeasts usually form?
A
- they usually form multicellular colonies
18
Q
- How can yeasts reproduce?
A
THEY CAN REPRODUCE:
- by sexual reproduction
- by asexual reproduction
19
Q
- What is an example of Asexual Reproduction?
A
-Budding
- this method is most used in Alcohol Fermentation
20
Q
- What is an example of Yeasts?
A
- Saccharomyces Cerevisiae
21
Q
- What kind of structure do Multicellular Fungi have?
A
- they have a filamentous structure
- this consists of Mycelia
22
Q
- What are the filaments of Multicellular fungi made of?
A
- they are made of Hyphae
23
Q
- What are Mycelia?
A
- these are networks of branches Hyphae
- they aid in the absorption of nutrients from different
surfaces
24
Q
- What are the 2 types of Hyphae?
A
- Septates
- Coenocytic Fungi
25
25. What are Septates?
- these consist of Septa
- most fungi have hyphae that are divided into cells by
Septa
THEY ALSO CONSIST OF PORES:
- these allow cell-to-cell movement of organelles
26
26. Define Septa.
- these are rings
- they are made of Hyphae cell walls
27
27. What is Coenocytic Fungi?
- these are also known as Aseostate
- they lack septa
- they have a continuous cytoplasmic mass
- it consists of hundreds or thousands of nuclei
28
28. What is the Reproductive Structure of Multicellular Fungi?
- the fruiting body
29
29. What is the Spore-producing structure of Multicellular Fungi?
- Sporangia
30
30. Label this diagram.
1 = Hyphae
2 = Reproductive Structures
3 = Spore-Producing Structures
4 = Mycelium
31
31. What are Mycelium?
- these are collections of different hyphae
32
32. What kind of Fungi can we see in this image?
- Septa Hypha
33
33. What kind of Fungi can we see in this image?
- Coenocytic Hyphae
- there are no septa
- there is no cell wall separation
34
34. What are Rhizoids?
- these are vegetative hyphae
- they are the roots found beneath the surface
