Question

Yeast is not included in protozoans but in fungi because

• A. it has chlorophyll
• B. it shows saprotrophic mode of nutrition
• C. it has eukaryotic organization
• D. cell wall is made up of cellulose and reserve food materials as starch

Answer 1

The correct option is B it shows saprotrophic mode of nutrition

Fungi shows saprotrophic mode of nutrition which absorb soluble organic matter from dead substrates whereas protozoans live as autotrophs, predators or parasites. Yeast (a unicellular and filamentous) belongs to the kingdom fungi because of saprotrophic mode of nutrition.
Protozoans and fungi both have eukaryotic organisation. Fungi and some ptotozoa also have cell walls. They are not the same as the plant cell walls made of cellulose.
