67. FUNGAL REPRODUCTION

Question 1

1. What do all kinds of Fungi produce?

Answer 1

• they produce spores

Question 2

2. What happens during Asexual Reproduction?

Answer 2

• there is Simple Cell division
• this is known as Binary Fission
• this leads to Budding

Question 3

3. What is Budding?

Answer 3

• this is when a new organism develops
• it develops from an outgrowth (bud)
• this bud separates it from the Parental cell

Question 4

4. What happens during Sexual Reproduction?

Answer 4

• there is the production of a Diploid Zygote
• this is (2n)

THIS HAPPENS THROUGH:
- the fusion of 2 haploid fungi
- these are (n) hyphae

Question 5

5. How are the Haploid (n) fungal spores produced?

Answer 5

• they are produced sexually
• they can also be produced asexually

Question 6

6. How does the Fungal zygote accomplish Sexual Reproduction?

Answer 6

• it does this through Meiosis
• it produces sexual spores

WE GO FROM A DIPLOID ZYGOTE (2n):
- to haploid spores (n)

Question 7

7. How does Fungi accomplish Asexual Reproduction?

Answer 7

• it does this through Mitosis
• it produces asexual spores

WE GO FROM A HAPLOID SPORE (n):
- to haploid spores (n)

Question 8

8. Is there a difference between Sexual and Asexual spores?

Answer 8

• no
• they are the exact same spores
• they just have different labels based on the method of
  their production

Question 9

9. Define Germination?

Answer 9

UNDER FAVOURABLE CONDITIONS:
- the spores will grow back to a vegetative cell
- this is also known as a Fungal Cell

WE GO FROM A SPORE:
- this undergoes germination
- to become a vegetative cell

Question 10

10. Under which conditions can spores survive?

Answer 10

• they can survive under harsh conditions

Question 11

11. What does this image show?

Answer 11

• this is a yeast that is undergoing Binary Fission

Question 12

12. What does this image show?

Answer 12

• this is a yeast that is Budding

Question 13

13. What does this image show?

Answer 13

• the Budding process

Question 14

14. What are the stages of Asexual Reproduction?

Answer 14

1. Spore Producing Structures
2. They produce haploid Spores
3. These spores undergo Germination
4. They produce Haploid Mycelium

Question 15

15. What are the stages of Sexual Reproduction?

Answer 15

1. Haploid Mycelium
2. These undergo Plasmogamy
   
   • this is a type of Cytoplasmic Fusion
3. They enter the Heterokaryotic Stage
4. Karyogamy takes places
   - this is a kind of Nuclear Fission
   - it is the fusion of 2 haploid nuclei
5. This produces a Zygote
   
   • this is diploid
6. The Zygote undergoes Meiosis
   - the products are Spores
   - they are Haploid
7. The haploid spores undergo Germination
