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.

- In basidiomycete fungi, where specifically do nuclei from parents combine to make offspring spores? a.) Basidia b.) Basidiospores c.) Basidiocarp d.) Secondary mycelium e.) Hyphaearrow_forwardA fungal hypha that contains two genetically different nuclei would be classified asa. monokaryotic.b. bikaryotic.c. homokaryotic.d. heterokaryoticarrow_forwardSome fungal species can undergo both sexual and asexual life cycles. During very hot seasons fungi prefer; Select one: a. Asexual reproduction by mitosis, to reduce its genetic diversity b. Asexual reproduction by mitosis to reduce the number of spores c. Asexual reproduction by mitosis to produce diploid cells d. Sexual reproduction by meiosis to produce haploid spores that can resist extreme conditions e. Asexual reproduction by mitosis, as this process needs less energyarrow_forward
- Which of the following is a characteristic of fungi?a. autotrophicb. cellulose cell wallsc. external digestiond. sexual reproduction common in most speciesarrow_forwardWhich of these statements are false for lichens? Please select all correct answers. a.) Fungal species are obligate symbionts b.) A lichen is two species engaged in commensalism c.) Algal species are facultative symbionts d.) Lichen fungi gain sugars from algae e.) The relationship is beneficial for both fungi and algaearrow_forwardDikaryotic 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_forward
- Which of the following statements about fungi is false?a. Most fungi are multicellular.b. Fungal cell walls are composed of cellulose.c. Most fungi are nonmotile.d. Fungi digest their food before ingesting it.arrow_forwardSome fungi can be viewed as coenocytic organisms that exhibit little differentiation. When differentiation does occur, such as in the formation of reproductive structures, it is preceded by septum formation. Why does this occur?arrow_forwardFungi play a variety of roles in the ecosystem. Discuss briefly each of the following roles stated below. Give specific examples whenever possible. 1. Decomposers 2. Mycorrhizae 3. Lichen Symbiont 4. Endophyte 5. Plant Pathogenarrow_forward
