Question

Yeast is not included in protozoans but in fungi because

• A. It has no chlorophyll.
• B. Some fungal hyphae grow in such a way that they give the appearance of pseudomycelium.
• C. It has eukaryotic organization.
• D. Cell wall is made up of cellulose and reserve food material as starch.

Answer 1

Answer: (B)

Some fungal hyphae grow in such a way that they give the appearance of pseudomycelium.

Yeast is an exception whereas all the fungi are filamentous and multicellular. But the other characteristics of yeast makes it a fungi, not a protozoan. Fungi have an absorptive method of food acquisition but protozoans have holozoic mode of nutrition. Fungi reproduce through spore formation or yeasts have budding mechanism but protozoans exhibit reproduction by gamete formation or by conjugation.

Therefore, the correct answer is option B.
