| 21. | Once two opposite mating types have made initial contact, they give rise to a zygospore through multiple steps.
|
| 22. | When the environment is favorable, the zygospore germinates, meiosis occurs, and haploid vegetative cells are released.
|
| 23. | When adequate conditions resume, the zygospore will germinate, undergo meiosis, and produce new haploid algal cells.
|
| 24. | Zygospore formation is the result of a multiple step process beginning with compatible mating type zygophores growing towards each other.
|
| 25. | A fungus that forms zygospores is called a zygomycete, indicating that the class is characterized by this evolutionary development.
|
| 26. | When the zygospore germinates, it undergoes meiosis, generating new haploid hyphae, which may then form asexual sporangiospores.
|
| 27. | These dark patches on the wall will eventually develop into warty structures that make up the thickness of the zygospore wall.
|
| 28. | Type 1 is when the nuclei fuse quickly, within a few days, resulting in mature zygospore having haploid nuclei.
|
| 29. | "Mortierella " forms zygospores that are the developmental consequence of plasmogamy between gametangia belonging to complementary mating types.
|
| 30. | A homothallic strain of Closterium forms selfing zygospores via the conjugation of two sister gametangial cells derived from one vegetative cell.
