(b) it shows saprotrophic mode of nutrition.
(c) it has eukaryotic organisation.
(d) cell wall is made up of cellulose and reserve food material as starch.

Answer 1

Dear student,

The suitable option is (b) it shows saprotrophic mode of nutrition.
explanation :- Although all fungi are multicellular and filamentous, but yeast is an exception. It is on the basis of other characteristics that makes yeast a fungi and not a protozoan. In fungi food acquisition method is absorptive but protozoans have saprotrophic mode of nutrition. Also, in fungi reproduction is through spore formation or budding in case of yeast but protozoans exhibit reproduction by gamete formation or by conjugation.
