What methods do Fungi use to reproduce?
|
Asexually: Budding, Fission, or Spore Formation
Sexually: Using Haploid Spores |
|
|
Asexual reproduction by Fungi comprises:
|
Budding
Fission Spore Formation |
|
|
Sexual Reproduction by Fungi is best explained by
|
THe fusion of haploid gametes from two parent fungi, one (+) and one (-).
Gametes arise from the Hyphae of each parent. Haploid gametes fuse and form a diploid zygote. Zygote stage is Diploid. Zygote undergoes meiosis (not mitosis) |
|
|
Zygote stage in Fungi sexual reproduction is: Haploid or Diploid?
|
Diploid
|
|
|
When the Zygote in sexual fungal reproduction is diploid, which process does it use to continue reproduction?
|
Straight to Meiosis, no mitosis is occurring.
|
|
|
What effect does going straight to Meiosis have on the diploid Fungal zygote?
|
It produces Haploid Spores which germinate and produce new haploid organisms.
This allows for genetic variability since the chromosomes are not genetically identical to either parent, rather a combination. |
|
|
Spores are seen in which type of fungal reproduction?
|
Both sexual and Asexual, not the same though
|
|
|
A cell or a body separates from the parent organism, grows, and becomes a new organism unto itself. What is this termed?
|
Budding.
A form of asexual reproduction in Fungi and Yeasts. |
|
|
A single Fungal cell divides to produce two new daughter cells. This is termed?
|
Fission.
A form of asexual reproduction |
|
|
A fungus produces spores and releases them from stem-like structures called Hyphae. This is termed?
|
Sporulation.
A form of asexual reproduction in fungus seen in bread mold. |
|
|
A fungus produces spores and releases them from stem-like structures called?
|
Hyphae
|
|
|
An undeveloped organism that survives in a hostile environmental condition like drought or heat was probably reproduced via ?
|
Sporulation
|
|
|
Why is Sporulation used as a mechanism of asexual reproduction in hostile environmental conditions?
|
A spore is metabolically inactive, encased in a thick protective wall. (DORMANT)
Under appropriate conditions only then will it germinate and form a new haploid fungus. Basically grows it's own seeds and holds them captive (in Hyphae) until conditions are good to release them. |
|
|
In budding 1 Haploid cell, it becomes ?
|
2 Haploid cells
|
|
|
1 Haploid cell reproducing to produce 2 haploid cells is characteristic of which type of reproduction in Fungi?
|
Budding
|
|
|
All forms of Fungal asexual reproduction share one common characteristic...
|
Produce offspring with identical genomes to that of the parent organism.
|
|
|
Hyphae role in Sexual reproduction of Fungi
|
Hyphae produce the gametes that precede sexual reproduction.
|
|
|
In sexual reproduction, what is ultimately derived from the meiotic division of a diploid zygote?
|
Haploid spores which are then encased in the Hyphae. This is why Sporulation is both sexual and Asexual.
