Question

From which of the following do developing sperms get nutrition?

• A. Sertoli cells
• B. Germinal epithelium
• C. Blood cell
• D. Leydig cells

Hint:

Sertoli cells are often referred to as the "nurse cells" of the testes, as they provide essential support and nutrients to developing sperm.

Answer 1

The Correct Option is A

Step 1: The role of Sertoli cells in sperm development.
Sertoli cells, found in the seminiferous tubules of the testes, provide physical support and nutrition to developing sperm cells. These cells also help regulate the process of spermatogenesis (sperm production).
Step 2: Analyze the options.
- Sertoli cells: These cells nourish the sperm and help maintain the blood-testis barrier, protecting developing sperm from harmful substances. - Germinal epithelium: This is the layer of cells where spermatogenesis begins, but it does not provide the direct nutrition to sperm. - Blood cells: While blood cells deliver oxygen and nutrients throughout the body, they are not directly involved in sperm nutrition in the testes. - Leydig cells: These cells produce testosterone, which is essential for spermatogenesis, but they do not provide direct nutrition to developing sperm.
Step 3: Conclusion.
Sertoli cells are the primary source of nutrition for developing sperm.
Final Answer: \[ \boxed{Sertoli \; cells} \]
