- A. Ascospore
- B. Yeast
- C. Rust
- D. Penicillium
Explanation: Final Explanation:This question tests fungal taxonomy, essential for medical students in infectious disease studies.
Correct answer: Yeast- A. Ascospores
- B. Basidiospores
- C. Conidia
- D. Both a and b
Explanation: The correct answer is ascospores. In yeasts, sexual reproduction typically involves the formation of ascospores, which are produced in a…
Correct answer: Ascospores- A. Ascomycetes
- B. Basidiomycetes
- C. Zygomycetes
- D. Deuteromycetes
Explanation: This question tests fungal taxonomy, essential for medical students in infectious disease studies.
Correct answer: Basidiomycetes- A. Rusts
- B. Mushrooms
- C. Bracket fungi
- D. Saccharomyces
Explanation: This question tests knowledge of fungal taxonomy, critical for medical students in mycology and infectious disease studies.
Correct answer: Saccharomyces- A. Dikaryotic cells
- B. Basidiospores
- C. Basidium
- D. All of these
Explanation: The correct answer is 'All of these.' Mushrooms are complex structures composed of dikaryotic cells, which are crucial in the life cycle…
Correct answer: All of these- A. Rusty disease spots on leaves and stem
- B. Brick red spores
- C. Ustilago is the most common smut
- D. All these
Explanation: The correct answer is Option C: Ustilago is the most common smut. Rusts and smuts are both types of fungi but have distinct differences.
Correct answer: Ustilago is the most common smut147. Smuts are called so:
- A. Spores resembling soot
- B. Spore mass replaces grain kernel in wheat
- C. Ustilago is the most common smut
- D. It causes loose smut of wheat
Explanation: The term 'smuts' refers to a range of fungi known for producing dark, powdery spore masses that resemble soot.
Correct answer: Spores resembling soot- A. Sac fungus
- B. Club fungus
- C. Imperfect fungus
- D. Conjugating fungus
Explanation: The disease cycle of loose smut of wheat is caused by fungi belonging to the Basidiomycota, commonly known as club fungi.
Correct answer: Club fungus- A. Zygomycota
- B. Deuteromycota
- C. Basidiomycota
- D. Ascomycota
Explanation: The correct answer is Deuteromycota. This group is often referred to as 'imperfect fungi' because they do not have a known sexual…
Correct answer: Deuteromycota- A. Asexual spores
- B. DNA sequence
- C. Sexual spores
- D. All these
Explanation: The correct answer is DNA sequence. In modern taxonomy, DNA sequencing is used to classify imperfect fungi as it provides detailed genetic…
Correct answer: DNA sequence- A. Conjugation
- B. Parasexuality
- C. Budding
- D. Transduction
Explanation: Parasexuality is the correct answer because it describes a process in deuteromycetes where genetic recombination occurs without the…
Correct answer: Parasexuality- A. They are also called imperfect fungi
- B. Their asexual spores are called conidia
- C. It is a heterogeneous polyphyletic group
- D. They have both sexual and asexual reproduction
Explanation: The correct answer is Option D: They have both sexual and asexual reproduction. This statement is not true about deuteromycetes.
Correct answer: They have both sexual and asexual reproduction- A. Lack of flagellated cells
- B. Thick walled zygote
- C. Dispersal of spores by wind
- D. Cytoplasmic flow throughout the hyphae
Explanation: The correct answer is cytoplasmic flow throughout the hyphae. This feature is not directly related to survival on land; it is a general…
Correct answer: Cytoplasmic flow throughout the hyphae- A. Below 5°C
- B. Above 50°C
- C. 5−50°C
- D. Both a and b
Explanation: Fungi are incredibly adaptable organisms that can survive in a broad range of temperatures.
Correct answer: Both a and b- A. Decomposition
- B. Bioremediation
- C. Bioindicator of pollution
- D. Mycorrhizal association
Explanation: The correct answer is Mycorrhizal association. This is a specific mutualistic relationship between fungi and plant roots, where both…
Correct answer: Mycorrhizal association- A. Mushrooms
- B. Morchella
- C. Amanita
- D. Aspergillus
Explanation: The correct answer is Amanita. Many Amanita species, such as the Amanita phalloides (death cap), are highly toxic and can be fatal if…
