69. ZYGOMYCETES

Question 1

1. What Phylum do Zygomycetes belong to?

Answer 1

• Phylum Zygomycota

Question 2

2. What kind of species do Zygomycetes consist of?

Answer 2

• they have many pathogenic species

Question 3

3. What are Zygomycetes named after?

Answer 3

• they are named after their characteristic
  Zygosporangia

Question 4

4. What is an example of Zygomycetes?

Answer 4

• Black Bread Mold

Question 5

5. What are the Spore-producing structures of Zygomycetes?

Answer 5

1. Sporangia
2. Zygosporangia

Question 6

6. What are Sporangia?

Answer 6

• these structures produce spores by Asexual
  Reproduction

Question 7

7. What are Zygosporangia?

Answer 7

• they contain sexually produced spores
• these are produced through Karyogamy and Meiosis

THESE SPORES:
- are resistant to freezing and drying
- they can survive in unfavourable conditions

Question 8

8. Do these images make sense?

Answer 8

• yes

Question 9

9. Label this diagram.

Answer 9

1. Sporangia
2. Spores
   - they are asexual
   - they are produced through Mitosis
3. Aerial Hyphae
4. Mycelium
5. Hyphae
6. Zygosporangium
   - these come from two different fungi and mycelia
   - they produce sexual spores through Meiosis

Question 10

10. What Phylum do Glomeromycetes belong to?

Answer 10

• they belong to Phylum Glomeromycota

Question 11

11. What do Glomeromycetes form?

Answer 11

• they form Arbuscular Mycorrhizae

Question 12

12. What are Mycorrhizae?

Answer 12

• these are the mutually beneficial relationships
  between fungi and plant roots

Question 13

13. What are Arbuscular Mycorrhizal Fungi?

Answer 13

• these are fungi that have Haustoria

Question 14

14. What are Haustoria?

Answer 14

• these are specialised Hyphae
• they penetrate the cell walls of Root Cells

Question 15

15. Define the Mutualistic Relationships between fungi and plants?

Answer 15

• the Mycorrhizal fungi delivers phosphate ions and
  minerals to the plant
• the plant provides an environment for the fungi to live
  in

Question 16

16. Does this image make sense?

Answer 16

• yes

Question 17

17. What Phylum do Ascomycetes belong to?

Answer 17

• they belong to the Phylum Ascomycota

NB:
- they have many pathogenic species

Question 18

18. What kind of spores can Ascomycetes produce?

Answer 18

• they can produce both sexual spores
• and asexual spores

Question 19

19. What do Ascomycetes consist of?

Answer 19

• they have spore producing structures
• they have a fruiting body

Question 20

20. What are the 2 types of Spore Producing Structures that we can find in Ascomycetes?

Answer 20

1. Asci
2. Condiophores

Question 21

21. What are Asci?

Answer 21

• these are structures that produce sexual spores
• they do this through Meiosis
• these spores are known as Ascospores

Question 22

22. Where are Asci located?

Answer 22

• they are located in the Ascocarps
• this is the fruiting body of the Ascomycetes

Question 23

23. What are Conidiophores?

Answer 23

• these are specialised Hyphae
• they produce Asexual spores
• this is done through the process of Mitosis
• these are known as Conidia

Question 24

24. What is the Fruiting body of the Ascomycetes?

Answer 24

• this is a multicellular structure
• it is a reproductive structure
• it contains spore-producing structures

Question 25

25. What greek words can we find in the term: “Ascomycetes”?

Answer 25

• ascom
• this means Sac
• it describes the structure of the Ascomycetes

Question 26

26. What are some examples of Ascomycetes?
