The correct Answer is:
To solve the fill-in-the-blank question, we will analyze each part step by step based on the information provided in the video transcript. ### Step-by-Step Solution: 1. **(i) Asexual spores in ascomycetes are**: - Ascomycetes reproduce asexually through methods such as fission, budding, and fragmentation. The asexual spores produced are known as **conidia**, which are formed externally. Therefore, the answer is **exogenous**. - **Answer**: Asexual spores in ascomycetes are **exogenous**. 2. **(ii) Sexual spores in basidiomycetes are**: - In basidiomycetes, the sexual spores are called **basidiospores**, which are produced exogenously at the tips of structures called sterigmata. Therefore, the answer is also **exogenous**. - **Answer**: Sexual spores in basidiomycetes are **exogenous**. 3. **(iii) Sexual spores developed in ascomycetes are**: - The sexual spores produced in ascomycetes are known as **ascospores**, which are formed within a sac-like structure called asci. These spores are produced internally, making them **endogenous**. - **Answer**: Sexual spores developed in ascomycetes are **endogenous**. 4. **(iv) Asexual spores developed in Alternaria are**: - Alternaria, a type of fungus, produces asexual spores known as **conidia**, which are formed externally. Thus, these spores are also **exogenous**. - **Answer**: Asexual spores developed in Alternaria are **exogenous**. ### Final Answers: - (i) Asexual spores in ascomycetes are **exogenous**. - (ii) Sexual spores in basidiomycetes are **exogenous**. - (iii) Sexual spores developed in ascomycetes are **endogenous**. - (iv) Asexual spores developed in Alternaria are **exogenous**.
