Describe the processes of plasmogamy and karyogamy in fungi?
Afghangurl
Karyogamy is the fusion of the nuclei in the cell, while Plasmogamy is the fusion of cytoplasm in the cell, but not the nuclei.

How does fungi diseases reproduce?
This is a very broad topic, and I will try to give a general overview. There are two main types of reproduction: sexual and asexual. Many fungi reproduce both ways, and fungal taxonomy is based in part on reproduction. Since there are fungal pathogens in all the major groups, I'll just cover them taxonomically. Basidiomycotina (subphylum of Dikaryomycota)--Sexual reproduction takes place when two compatible hyphae meet. Plasmogamy (fusion of the cells) occurs but karyogamy (fusion of the nuclei) does not, resulting in a new individual with cells containing two haploid nuclei. When conditions are right, a basidiocarp is formed. The most well known basidiocarps are the mushrooms, but there are others. In a special layer of cells called the hymenium, karyogamy finally occurs. This is followed by meiosis, which gives rise to haploid spores. These spores are then allowed to disperse by wind, animals, water, etc. Ascomycotina--Sexual reproduction occurs in a similar manner. The main differences are the way to spores are produced and dispersed. Many individuals of Ascomycotina do not both with sexual reproduction and rely exclusively on asexual reproduction. When conditions are right, the mycelium will give rise to sporangiophores. These are specialized hyphae that will generate and help disperse the conidia, or asexual spores. Conidia are produced rapidly and in high numbers. Many are dispersed by the wind, which allows them to get everywhere. Glomeromycota/Zygomycota--These are mainly opportunistic pathogens. They reproduce asexually in a similar manner to Ascomycotina. When conditions are right for sex, two hyphae will undergo plasmogamy and karyogamy. This gives rise to a resistant structure containing a zygospore. It will germinate and give rise to a sporangiophore and spores that can be dispersed by the wind. Chytridiomycota/Blastocladiomycota/Neocallimastigomycota--These groups mainly reproduce asexually. Their sporangia release flagellated zoospores, which swim to a new substrate. There is some sexual reproduction, but the diversity of ways they do it is too much to be briefly covered.
Why do you use the terms Monera and bacteria to describe a kingdom?
The six kingdoms in organism classification are: animals, plants, protists, fungi, archaebacteria, and eubacteria.
What sexual processes in fungi generate genetic variation?
karyogamy and meiosis
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.
Which term describes the fusion of cytoplasm from two individuals?
Fungi reproduction
Are gametes in fungi meiosis or mitosis?
SomaticSomatic cells reproduce by mitosis. Gametes are produced by mieosis

What kingdom includes organisms that grow multicellular filaments that it processes as food?
fungi
How do fungi obtain the energy needed to carry out life processes?
Fungi get their energy from living or dead organisms. They will usually specialize in living or dead and it is rare that they can do both.
What term do biologists use to describe organisms such as bacteria and fungi to describe this group of diseases?
These organisms are called Pathogenes.

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.
