Select the correct match from the given option.
1 Occurrence ofdikaryotic stage - ascomycetes and basidiomycetes.
2 Saprophytes - They are autotrophic and absorb soluble organic matter from dead substrates.
3 Vegetative mean of reproduction in fungi fragmentation, budding andsporangiophores,
4 Steps involved in asexual cycle offungl plasmogamy, karyogamy and meiosis in zygote resulting in haploid spores.
Explanation:
(a) Saprophytes are heterotrophic and absorb soluble organic matter from dead substrates. Vegetative mean of reproduction in fungi are fragmentation, budding and fission. Steps involved in sexual cycle of fungi are plasmogamy, karyogamy and meiosis in zygote resulting in haploid spores.

1 phycomycetes
2 zygomycetes
3 deuteromycetes
4 basidiomycetes
Explanation:
(b) When moist bread is kept exposed in air, it becomes mouldly and black because spores are present in the bread.
Q 37. Ustilago causes plant disease known as#[examname: NCERT Page-24 / N-18]#
(a.) rust
(b.) Bovine spongiform encephalopathy
(c.) Cr-Jacob disease
(d.) Black smut
Ans: d
Exp: (d) Smut disease is caused by Ustilago species of basidiomycetes fungi. It is characterized by formation of black coloured chlamydospores or teleutospores (called smut spores) due to which the affected part becomes black.
Q 38. A fungus contains cells with two nuclei from different genomes. The nucleido not fuse but divide independently and simultaneously as new cells are formed. This fungus belongs to #[examname: NCERT Page-24 / N-18]#
(a.) phycomycetes
(b.) zygomycetes
(c.) deuteromycetes
(d.) basidiomycetes
Ans: d
Exp: (d) Basidiomycetes are commonly known as club fungi. They are fungus whose spores develop in basidia. They include the majority of familiar mushrooms and toadstools.

3 Yeast used in making bread and beer is a fungus.
4 Nostoc and Anabaena are examples of protista.
Explanation:

4 zoospores
Explanation:
(b) In fungi, asexual reproduction takes place by spores-called conidia or sporangiospores or zoospores, and sexual reproduction is by oospores, ascospores and basidiospores.
