- Option 4)
Saccharomyces
Answers (3)
As we learnt in
Basidiomycetes / Club fungi -
- Mycelium is septate and branched.
- Sexual reproduction is somatogamy.
- They decompose cellulose and lignin.
- Basidiospores formed exogenously on sterigmata
- Fruiting body is basidiocarp.
- wherein
Eg. Agaricus, Ustilago, Puccinia.
Deuteromycetes / Fungi imperfecti -
- Mycelium is seperate and branched.
- Sexual reproduction absent
- Fruiting body absent.
- Asexual reproduction by conidia.
- wherein
Eg. Alternaria, Trichoderma.
Ascomycetes / Sac fungi -
- Mycelium is septate and branched.
- Sexual reproduction is Isogamy or anisogamy.
- Four to eight ascospores are formed in an ascus.
- Fruiting body is Ascocarp.
- Centrum is present.
- wherein
Eg. Saccharomyces, cerevisiae, Baker's yeast, Penicillium.
In Agaricus (a genus of basidiomycetes), basidiospores or meiospores are produced exogenously.
-Neurospora (a genus of ascomycetes) produces ascospores as meiospores but endogenously inside the ascus.
-Alternaria (a genus of deuteromycetes) does not produce sexual spores.
-Saccharomyces (Unicellular ascomycetes) produces ascospores, endogenously.
Option 1)
Agaricus
Correct
Option 2)
Alternaria
Incorrect
Option 3)
Neurospora
Incorrect
Option 4)
