What happens when hyphae of different mating types meet?
When hyphae of different mating types meet, they can fuse together in a process called plasmogamy. This fusion forms a structure known as a dikaryon, where two distinct nuclei coexist within the same hyphal compartment. This dikaryotic mycelium can then undergo karyogamy, where the nuclei fuse to form a diploid nucleus, initiating the formation of sexually reproductive structures such as mushrooms.
Differentiate sexual and asexual reproduction?
sexual reproduction have phermone signals which say yes or no to proceed and produce. Cell fusion via connections between hyphae (plasmogamy)Heterokaryogamy- intervening stage in which cells have haploid nuclei from two parents. Nuclear fusion (karyogamy) teh diploid phase following karyogamy is short lived and undergoes meiosis producing haploid spores.Asexual reproduction. Many fungi can reproduce asexually. Molds and yeasts are called imperfect fungi because they can only undergo asexual reproduction and NOT SEXUAL.
Where does plasmogamy occur?
It occurs in fungi .
What is the result of plasmogamy?
Plasmogamy is the fusion of two or more cells or protoplasts without fusion of the nuclei, as occurs in higher terrestrial fungi.
What is the difference between plasmogamy and karygamy?
Plasmogamy is the unification or fusion of two cell's cytoplasm while their nuclie are still distinct whereas karygamy is the unification or fusion of 2 nuclei
Describe the processes of plasmogamy and karyogamy in fungi?
Plasmogamy is the fusion of cytoplasm from two haploid fungal cells, resulting in the formation of a dikaryotic cell with two separate haploid nuclei. Karyogamy is the fusion of the two haploid nuclei within the dikaryotic cell, leading to the formation of a diploid nucleus, which eventually undergoes meiosis to produce haploid spores.
Which term describes the fusion of cytoplasm from two individuals?
Cytoplasmic exchange or cytoplasmic transfer describes the fusion of cytoplasm from two individuals. This process can result in the sharing of organelles, proteins, and other cellular components between the two cells.
What occurs underground between the time a basidiospore germination and a mushroom button forms?
basidiospore germinate to form mycelium ,two compatible monocaryotic mycelim fuse together and form dicaryotic mycelium bv plasmogamy .only secondary mycelium form fruit bodies of mushroom.
In most fungi is fertilization complete after the cells fuse together?
No, in most fungi, fertilization is not complete after the cells fuse together. Fusion of the cells (plasmogamy) is followed by the fusion of their nuclei (karyogamy) to form a diploid zygote, which then undergoes meiosis to produce haploid spores. This process completes the sexual cycle in most fungi.
What happens when mycelia of two different mating strains meet?
When mycelia of two different mating strains meet, they undergo a process called plasmogamy where cytoplasmic contents are exchanged, but nuclei remain separate. This fusion forms a dikaryotic mycelium with two genetically distinct nuclei in each cell. Subsequent phases of mating result in karyogamy, where nuclei fuse to form a diploid nucleus, initiating sexual reproduction in fungi.
What happens when hyphae of different mating types meet?
When hyphae of different mating types meet, they can fuse together in a process called plasmogamy. This fusion forms a structure known as a dikaryon, where two distinct nuclei coexist within the same hyphal compartment. This dikaryotic mycelium can then undergo karyogamy, where the nuclei fuse to form a diploid nucleus, initiating the formation of sexually reproductive structures such as mushrooms.
Why was the name given to three of the fungal phyla is based on?
these are options...i need help too! A. the structure in whihc karyogamy occurs during sexual reproduction. B. the location of plasmogamy during sexual reproduction. C. the location of the heterokaryotic stage in the life cycle D. the structure that produces asexual spores E. their ancestral origin
What is the case fo the reproductive cells in zygote fungi?
There are two types of fungi, unicellular and multicellular and they have different names for the reproductive cells for alot of different types. For the spore type fungi the reproductive cells are called zygosporangium.
How does fungi diseases reproduce?
Fungi diseases reproduce through spores, which are microscopic structures that are released into the environment. These spores can be carried by wind, water, or animals to new locations where they can germinate and infect new hosts. Fungi can also reproduce sexually through the fusion of specialized reproductive structures called gametes.
