The correct Answer is:
To determine which phase includes meiosis during spermatogenesis, we can analyze the provided options step by step. ### Step-by-Step Solution: 1. **Understanding Spermatogenesis**: - Spermatogenesis is the process of sperm cell development that occurs in the seminiferous tubules of the testes. It involves several phases: multiplication, growth, maturation, and spermiation. 2. **Analyzing the Phases**: - **Phase of Multiplication**: - This phase involves the rapid division of sperm mother cells (spermatogonia) through mitosis. Therefore, this phase does not involve meiosis. - **Phase of Growth**: - In this phase, the primary spermatocytes grow and prepare for the next stage. It does not involve meiosis but rather the enlargement of cells. - **Phase of Maturation**: - This is the critical phase where meiosis occurs. The primary spermatocytes undergo meiosis, resulting in the formation of secondary spermatocytes. This is a reductional division, which is the hallmark of meiosis. - **Phase of Spermiation**: - This phase involves the release of mature sperm from the seminiferous tubules and does not involve meiosis. 3. **Conclusion**: - The phase that includes meiosis during spermatogenesis is the **Phase of Maturation**. ### Final Answer: - The correct answer is the **Phase of Maturation**.
