Bacteria and yeast are similar in all the following features except that
1 both are unicellular.
2 both are prokaryotes.
3 both are capable of causing fermentation.
4 both produce spores.
Explanation:
(b) Bacteria are prokaryotes while yeast belongs to the-kingdom Fungi (they are multicellular eukaryotes). Yeast is exception in fungi because it is unicellular but forms pseudomycelium.

Which class of fungi lacks sex organs but the process ofplasmogamy is brought about by fusion of two vegetative or somatic cells of different strains or genotypes?
1 Sac fungi
2 Imperfect fungi
3 Bracket fungi
4 Phycomycetes
Explanation:
(b) Bracket fungi belong to basidiomycetes. This class of fungi lacks sex organs but the process of plasmogamy is brought about by fusion of two vegetative or somatic cells of different strains or genotypes.

Assume that two normal hyphal cells of different fungal mating types unite. After a period of time, the cell between these cells will dissolve producing a
1 mycelium
2 fruiting body
3 zygote
4 dikaryotic cell, which is also heterokaryotic
Explanation:
(d) When two hyphal cells of different mating types fuse, they form a dikaryotic cell which is heterokaryotic.
