16
Q
  1. 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
  1. What kind of colonies do Yeasts usually form?
A
  • they usually form multicellular colonies
18
Q
  1. How can yeasts reproduce?
A

THEY CAN REPRODUCE:
- by sexual reproduction
- by asexual reproduction

19
Q
  1. What is an example of Asexual Reproduction?
A

-Budding
- this method is most used in Alcohol Fermentation

20
Q
  1. What is an example of Yeasts?
A
  • Saccharomyces Cerevisiae
21
Q
  1. What kind of structure do Multicellular Fungi have?
A
  • they have a filamentous structure
  • this consists of Mycelia
22
Q
  1. What are the filaments of Multicellular fungi made of?
A
  • they are made of Hyphae
23
Q
  1. What are Mycelia?
A
  • these are networks of branches Hyphae
  • they aid in the absorption of nutrients from different
    surfaces
24
Q
  1. What are the 2 types of Hyphae?
A
  1. Septates
  2. Coenocytic Fungi
25
Q
  1. What are Septates?
A
  • 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
Q
  1. Define Septa.
A
  • these are rings
  • they are made of Hyphae cell walls
27
Q
  1. What is Coenocytic Fungi?
A
  • these are also known as Aseostate
  • they lack septa
  • they have a continuous cytoplasmic mass
  • it consists of hundreds or thousands of nuclei
28
Q
  1. What is the Reproductive Structure of Multicellular Fungi?
A
  • the fruiting body
29
Q
  1. What is the Spore-producing structure of Multicellular Fungi?
A
  • Sporangia
30
Q
  1. Label this diagram.
A

1 = Hyphae
2 = Reproductive Structures
3 = Spore-Producing Structures
4 = Mycelium

31
Q
  1. What are Mycelium?
A
  • these are collections of different hyphae
32
Q
  1. What kind of Fungi can we see in this image?
A
  • Septa Hypha
33
Q
  1. What kind of Fungi can we see in this image?
A
  • Coenocytic Hyphae
  • there are no septa
  • there is no cell wall separation
34
Q
  1. What are Rhizoids?
A
  • these are vegetative hyphae
  • they are the roots found beneath the surface
