The correct Answer is:
To determine which statements are correct regarding the given options, we will analyze each statement one by one: ### Step-by-Step Solution: 1. **Statement (a): Asexual reproduction is absent in deuteromycets.** - **Analysis:** Deuteromycetes, also known as Fungi Imperfecti, are characterized by the absence of a known sexual reproductive stage. However, they do reproduce asexually through conidia or other means. Therefore, this statement is **false**. 2. **Statement (b): Plasmogamy is brought about by fusion of two vegetative cells of the same strain in basidiomycetes.** - **Analysis:** Plasmogamy refers to the fusion of cytoplasm from two different cells. In basidiomycetes, plasmogamy occurs between different strains (or mating types), not the same strain. Thus, this statement is also **false**. 3. **Statement (c): Basidiospores and ascospores are produced exogenously and endogenously respectively.** - **Analysis:** Basidiospores are produced externally (exogenously) on the basidia, while ascospores are produced internally (endogenously) within asci. Therefore, this statement is **true**. 4. **Statement (d): Bracket fungi is another name of some basidiomycetes.** - **Analysis:** Bracket fungi, also known as shelf fungi, are indeed a type of basidiomycetes. They are characterized by their shelf-like appearance on trees and logs. Thus, this statement is **true**. ### Conclusion: The correct statements are: - **(c)** Basidiospores and ascospores are produced exogenously and endogenously respectively. - **(d)** Bracket fungi is another name of some basidiomycetes. Therefore, the correct answer is **(c) and (d)**. ---
