Fungi, Algae, Protozoans, and Helminths

Which one of the following statements about fungi is true?

• All fungi are unicellular

• All fungi are eukaryotic

• All fungi are autotrophic

• Most fungi are anaerobic

• Most fungi are pathogenic to humans

Long filaments of fungal cells joined together are:

• Yeasts

• Spores

• Stipes

• Septa

• Hyphae

A mold obtains nutrients by absorption through:

• Vegetative hyphae

• Aerial hyphae

• Blastoconidia

• The ascus

• Yeasts

Fungal reproductive spores are produced:

• By yeasts

• On aerial hyphae

• On vegetative hyphae

• By the thallus

• Fungi don’t produce reproductive spores

Fungi, more often than bacteria, are responsible for decomposition of plant material because:

• They are aerobic.

• They can tolerate low-moisture conditions.

• They prefer a neutral environment (pH 7).

• They have a fermentative metabolism.

• They cannot tolerate high osmotic pressure.

Pathogenic dimorphic fungi:

• Are yeast like at 25°C

• Are yeast like at 37°C

• Are filamentous at 37°C

• Are filamentous but cannot reproduce sexually at 25°C

• Have no sexual spore type at any temperature

Sexual spores produced by fungi:

• Are often produced in response to environmental changes

• Include ascospores, zygospores, and basidospores

• Undergo meiosis to produce asexual spores

• Are used to classify fungi taxonomically

• All of the above are true

Which of the following pairs is not correctly matched?

• Plasmogamy: union of two haploid cells.

• Karyogamy: fusion of nuclei.

• Meiosis: cell division resulting in haploid cells.

• Anamorph: produces asexual spores only.

• Deuteromycota: a phylum of fungi based on sexual spore type.

Which spore results from the fusion of two nuclei from different strains of the same type of fungus and is formed in a sac?

• Zygospore

• Ascospore

• Basidiospore

• Deuterospore

• Blastospore

Which spore results from the fusion of two nuclei from different strains of the same type of fungus and is found externally on a pedestal?

• Zygospore

• Ascospore

• Basidiospore

• Deuterospore

• Blastospore
