The correct Answer is:
To determine which statement is wrong among the given options, we will analyze each statement one by one. **Step 1: Analyze Statement (a)** **Statement:** Sertoli cells provide nutrition to the developing male germ cells. **Analysis:** This statement is true. Sertoli cells, also known as nurse cells, play a crucial role in supporting and nourishing the developing male germ cells (spermatids) during spermatogenesis. **Step 2: Analyze Statement (b)** **Statement:** Leydig cells synthesize and secrete androgens. **Analysis:** This statement is also true. Leydig cells, located in the testes, are responsible for the production and secretion of androgens, primarily testosterone, which is essential for male reproductive functions. **Step 3: Analyze Statement (c)** **Statement:** Secretions of the acrosome help the sperm to enter the cytoplasm of the ovum. **Analysis:** This statement is true as well. The acrosome is a cap-like structure on the head of the sperm that contains enzymes (such as hyaluronidase) that help the sperm penetrate the outer layers of the ovum, specifically the zona pellucida, allowing fertilization to occur. **Step 4: Analyze Statement (d)** **Statement:** Secondary spermatocytes are diploid. **Analysis:** This statement is incorrect. Secondary spermatocytes are actually haploid cells. They are formed from primary spermatocytes (which are diploid) after the first meiotic division. The primary spermatocytes undergo meiosis I to produce two secondary spermatocytes, each of which contains half the number of chromosomes (haploid). **Conclusion:** The wrong statement among the options is (d) "Secondary spermatocytes are diploid." ---
