Fungi imperfecti ( Deuteromycetes ) lack

Options

A. spores
B. sexual reproduction
C. asexual reproduction
D. hyphae

Answer

### Step-by-Step Solution:

1. **Understanding Fungi Imperfecti (Deuteromycetes)**:
- Fungi imperfecti, also known as Deuteromycetes, are a group of fungi that do not fit into the traditional classification based on their reproductive structures.

2. **Characteristics of Deuteromycetes**:
- These fungi are termed "imperfect" because their sexual reproductive forms have not been observed. This is a key characteristic that distinguishes them from other fungi.

3. **Reproductive Methods**:
- While Deuteromycetes can reproduce asexually (through spores), they lack the ability to reproduce sexually. This absence of sexual reproduction is a defining feature of this group.

4. **Analyzing the Options**:
- The question asks what Fungi Imperfecti lack.
- Option 1: Spores - This is incorrect because they do produce asexual spores.
- Option 2: Sexual reproduction - This is correct as they lack the observed sexual reproductive structures.
- Option 3: Asexual reproduction - This is incorrect since they can reproduce asexually.
- Option 4: Hyphae - This is incorrect as hyphae are present and serve as the structure for attachment.

5. **Conclusion**:
- The correct answer is that Fungi Imperfecti (Deuteromycetes) lack sexual reproduction.

### Final Answer:
Fungi Imperfecti (Deuteromycetes) lack sexual reproduction.
