Which of the following statements are correct?
(a) Asexual reproduction is absent in deuteromycets
(b) Plasmogamy is brought about by fusion of two vegetative cells of same strain in basidiomycetes
(c) Basidiospores and ascospores are produced exogenously and endogenously respectively
(d) Bracket fungi is another name of some basidiomycetes

Options

A. a, b
B. a, c
C. c, d
D. c, b

Answer

To determine which statements are correct regarding fungi, let's analyze each statement step by step:

### Step 1: Analyze Statement (a)
- **Statement (a)**: "Asexual reproduction is absent in deuteromycets."
- **Analysis**: This statement is **false**. Deuteromycetes, also known as Fungi Imperfecti, are characterized by their asexual reproduction. They do not have a known sexual reproductive stage, which is why they were classified separately.

### Step 2: Analyze Statement (b)
- **Statement (b)**: "Plasmogamy is brought about by fusion of two vegetative cells of the same strain in basidiomycetes."
- **Analysis**: This statement is also **false**. Plasmogamy involves the fusion of two vegetative cells, but they must be of different strains (or mating types) in basidiomycetes. Therefore, the statement is incorrect.

### Step 3: Analyze Statement (c)
- **Statement (c)**: "Basidiospores and ascospores are produced exogenously and endogenously respectively."
- **Analysis**: This statement is **true**. Basidiospores are produced externally (exogenously) on the basidia in basidiomycetes, while ascospores are produced internally (endogenously) within the asci in ascomycetes.

### Step 4: Analyze Statement (d)
- **Statement (d)**: "Bracket fungi is another name for some basidiomycetes."
- **Analysis**: This statement is **true**. Bracket fungi, also known as shelf fungi, are indeed a type of basidiomycetes. They are commonly found growing on trees and are recognized for their shelf-like appearance.

### Conclusion
Based on the analysis:
- **Correct Statements**: (c) and (d)
- **Incorrect Statements**: (a) and (b)

### Final Answer
The correct statements are:
- (c) Basidiospores and ascospores are produced exogenously and endogenously respectively.
- (d) Bracket fungi is another name for some basidiomycetes.
