The correct Answer is:
To determine the ploidy level of the scutellum in a monocotyledonous embryo, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Ploidy**: Ploidy refers to the number of sets of chromosomes in a cell. The common types of ploidy are: - **Haploid (n)**: One set of chromosomes. - **Diploid (2n)**: Two sets of chromosomes. - **Triploid (3n)**: Three sets of chromosomes. 2. **Identifying the Scutellum**: The scutellum is a specialized cotyledon found in monocotyledonous plants (monocots). It plays a crucial role in the absorption of nutrients during seed germination. 3. **Determining the Ploidy of the Scutellum**: In monocots, the scutellum is derived from the zygote, which is formed after fertilization. The zygote is diploid (2n) because it is formed by the fusion of haploid gametes (sperm and egg). 4. **Conclusion**: Since the scutellum originates from the diploid zygote, it retains the diploid ploidy level. Therefore, the ploidy level of the scutellum is **diploid (2n)**. 5. **Final Answer**: The correct answer is **B) Diploid**.
