Phylum Zygomycota
2
Conjugation
The hyphae develop extensions for mating called gametes that fuse together.
Their nuclei mix and form a thick walled structure called a ZYGOSPORE which is a resting or dormant stage
-can survive hostile environments
When conditions improve, the Diploid (2n) Zygospore cracks open and a SPORANGIOPHORE grows and forms a SPORANGIUM . The sporangium releases thousands of haploid (n) spores
Rhizopus stolonifer
RHIZOIDS - (Root-Like Structures) penetrate the food surface.
STOLONS -
- connect one group of rhizoids to another.
- spread across the surface of the food source.
Phylum Zygomycota
Class Zygomycetes
- found primarily in soil.
- Most primitive terrestrial fungi.
- Include breadmolds (Rhizopus stolonifera)
- Hyphae are aseptate.
- Fusion of hyphae leads directly to the formation of a zygote.
Reproduction of Bread mold
-Most common: asexual reproduction
However...
When hyphae of different mating types grow close to each other the mold may reproduce sexually by conjugation.
