Choose incorrect match w.r.t. different classes of fungi

Options

A. Oomycetes - zoospore - gametic - copulation
B. Zygomycetes - sporangiospore - zygophore
C. Ascomycetes - conidia - monokaryotic aseptate mycelium
D. Phycomucetes - algal and conjugation fungi - coenocytic mycelium

Answer

To solve the question of choosing the incorrect match with respect to different classes of fungi, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Classes of Fungi**:
- Fungi are classified into various classes, including Zygomycetes, Ascomycetes, and Phycomycetes. Each class has distinct characteristics and modes of reproduction.

2. **Evaluate the Options**:
- **Option 1: Oomycetes** - These fungi undergo gametic reproduction and copulation. This is a true statement as Oomycetes are known for their sexual reproduction involving gametes.
- **Option 2: Zygomycetes** - They reproduce by forming zygospores. This is also a true statement as Zygomycetes are characterized by the formation of zygospores during sexual reproduction.
- **Option 3: Ascomycetes** - They produce conidia, which are asexual spores. However, the statement claims they are monokaryotic, which is incorrect because Ascomycetes can also have a dikaryotic phase during their life cycle.
- **Option 4: Phycomycetes** - These are known as conjugation fungi, and they also exhibit dikaryophase. This statement is true as Phycomycetes can form a sinusitic mycelium.

3. **Identify the Incorrect Match**:
- After evaluating all options, the incorrect match is found in **Option 3: Ascomycetes**, which states they are monokaryotic. This is incorrect because Ascomycetes can exist in a dikaryotic phase.

### Conclusion:
The incorrect match with respect to different classes of fungi is **Ascomycetes**, as they are not exclusively monokaryotic; they can also be dikaryotic.
