Introduction: Fungi are eukaryotic organisms that are distributed widely on the Earth. They are heterotrophs. They play an important ecological role. Most fungi are found to be free-living in the soil and some form symbiotic association with plants. Fungi may undergo either sexual or asexual reproduction and produce a large number of spores.
b.
To explain: The term septa that relates to the structure and reproduction of fungi.
c.
To explain: The term coenocytic that relate to the structure and reproduction of fungi.
d.
To explain: The term plasmogamy that relates to the structure and reproduction of fungi.
e.
To explain: The term heterokaryon that relates to the structure and reproduction of fungi.
f.
To explain: The term dikaryon that relates to the structure and reproduction of fungi.
g.
To explain: The term karyogamy that relates to the structure and reproduction of fungi.

- The life cycle of most fungi is best described by which of the following statements? A Fungi are unique and have different mechanisms of reproduction B Fungi only reproduce sexually C Fungi have both sexual and asexual portions of their life cycle D Fungi only reproduce asexually E None of thesearrow_forwardWhich of the following best describes Basidiomycota? A. The vast majority of spores formed are asexual. B. Spores line up in a sac in the order they were formed by meiosis. C. Monokaryotic hyphae fuse to grow into a heterokaryotic mycelium. D. No sexual stage has been found.arrow_forwardDescribe the morphology of a fungi and what is it about their structure that makes them so good at being symbionts?arrow_forward
- Dikaryotic cells A. contain two nuclei per cell B. produce two spores per hypha C. contain diploid nuclei D. have two hyphae per fruiting body E. contain pairs of homologous chromosomesarrow_forwardWhich statement below is true about the most recently evolved groups (2 groups) of fungi? a the two most recently evolved groups are zygomycetes and ascomycetes b they have hyphae with crosswalls c they are only found in aquatic environmentsarrow_forwardWhy do fungi mostly occur in moist habitat? a) Their thin hyphae lose water quickly making them vulnerable to dehydration b) Their spores are small and vulnerable to dehydration c) Their sperm require water to swim to eggs d) Conidiophores require moisture for dispersal e) A and C f) C and Darrow_forward
