Golgi complex takes part in formation of

Options

A. acrosome of sperm
B. cortical granules and vitelline membrane of oocytes
C. yolk in egg
D. all of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Golgi Complex**: The Golgi complex, also known as the Golgi apparatus, is an essential organelle in eukaryotic cells responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

2. **Formation of Acrosome of Sperm**: The Golgi complex plays a crucial role in the formation of the acrosome, which is a cap-like structure that covers the anterior part of the sperm. The acrosome contains enzymes that help the sperm penetrate the egg during fertilization.

3. **Formation of Cortical Granules and Vitelline Membrane**: The Golgi complex is also involved in the formation of cortical granules, which are found in oocytes (egg cells). These granules release substances that help prevent polyspermy (fertilization by multiple sperm). Additionally, the Golgi complex contributes to the formation of the vitelline membrane, which surrounds the oocyte and plays a role in fertilization.

4. **Formation of Yolk in Egg**: The Golgi complex is involved in the formation of yolk in the egg (yolk is a nutrient-rich substance that provides nourishment to the developing embryo). The Golgi apparatus helps in the synthesis and transport of proteins and lipids that make up the yolk.

5. **Conclusion**: Since the Golgi complex is involved in the formation of the acrosome of sperm, cortical granules, vitelline membrane of oocytes, and yolk in eggs, all the options provided in the question are correct. Therefore, the answer is "all of the above."

**Final Answer**: The Golgi complex takes part in the formation of acrosome of sperm, cortical granules, vitelline membrane of oocytes, and yolk in eggs. Hence, the correct option is "all of the above."
