Which of the following is NOT a characteristic of Kingdom Animalia?

Lack of a cell wall
Heterotrophic mode of nutrition
Presence of chlorophyll
Multicellular body organization
3

Animals lack chlorophyll and obtain their food through ingestion.

Which type of asexual spores are produced by fungi like Rhizopus?

Conidia
Ascospores
Sporangiospores
Basidiospores
3

Rhizopus produces asexual sporangiospores inside a sporangium.

Which of the following statements about protozoans is incorrect?

Protozoans are unicellular eukaryotic organisms.
Protozoans can be free-living or parasitic.
Protozoans reproduce only sexually.
Protozoans exhibit various forms of locomotion.
3

Which of the following organisms is known as 'water mold'?

Rhizopus
Albugo
Amoeba

2

Albugo, a member of Phycomycetes, is commonly referred to as 'water mold.'

Which of the following statements about fungi is correct?

Fungi store carbohydrates as starch.
Fungi lack a cell wall.
Fungal cell walls are composed of chitin.
Fungi perform photosynthesis.
3

Fungal cell walls contain chitin, unlike plant cell walls, which contain cellulose.

Which of the following is a characteristic of euglenoids?

They have silica-embedded cell walls
They can switch between autotrophic and heterotrophic nutrition
They are obligate parasites
They lack flagella
2

Euglenoids, like Euglena, can perform photosynthesis in light (autotrophic) or feed heterotrophically in darkness, and they possess flagella for movement.

Which of the following statements about dinoflagellates is correct?

Dinoflagellates are prokaryotic organisms.
Dinoflagellates move using flagella.
Dinoflagellates have peptidoglycan in their cell walls.
Dinoflagellates are incapable of photosynthesis.
2

Dinoflagellates use two flagella for movement, one longitudinal and one transverse.

Which of the following is a characteristic of Ascomycetes?

Produce basidiospores
Form asci containing ascospores
Lack sexual reproduction
Cause red tides
2

Ascomycetes, or sac fungi, produce ascospores within sac-like structures called asci, distinguishing them from Basidiomycetes, which produce basidiospores.

What is the primary role of heterocysts in cyanobacteria?

Photosynthesis
Nitrogen fixation
Spore formation
Protein synthesis
2

Heterocysts are specialized nitrogen-fixing cells in cyanobacteria like Nostoc and Anabaena.

Which of the following classes of fungi includes mushrooms?

Ascomycetes
Phycomycetes
Basidiomycetes
