Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of fungal classification and their fruiting body types.
Step 2: Detailed Explanation:
Ascomycetes produce ascospores in asci.
Based on the type of fruiting body, they are classified as:
- Perithecial ascomycetes: Produce perithecia (flask-shaped fruiting bodies).
- Cleistothecial ascomycetes: Produce cleistothecia (closed fruiting bodies).
Gibberella (D) is a perithecial ascomycete.
It produces perithecia and is the sexual stage of Fusarium.
Other options:
- Erysiphe (A): Cleistothecial ascomycete (powdery mildew).
- Uncinula (B): Cleistothecial ascomycete (powdery mildew).
- Podosphaera (C): Cleistothecial ascomycete (powdery mildew).
Thus, Gibberella is a perithecial ascomycete.
Step 3: Final Answer:
Thus, Gibberella is a perithecial ascomycete, which corresponds to option (D).
