Which cell organelle is the major site for synthesis of glycoprotein and glycolipid?

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the cell organelle that is primarily responsible for the synthesis of glycoproteins and glycolipids.

2. **Identifying Key Organelles**: In eukaryotic cells, the main organelles involved in the synthesis and modification of proteins and lipids are the Endoplasmic Reticulum (ER) and the Golgi apparatus.

3. **Role of the Endoplasmic Reticulum (ER)**: The synthesis of glycoproteins and glycolipids begins in the Endoplasmic Reticulum. The ER is responsible for the initial assembly of these molecules.

4. **Function of the Golgi Apparatus**: After synthesis in the ER, glycoproteins and glycolipids are transported to the Golgi apparatus. The Golgi apparatus modifies, sorts, and packages these molecules for secretion or for use within the cell.

5. **Conclusion**: The Golgi apparatus (or Golgi body) is the major site for the synthesis and modification of glycoproteins and glycolipids. It receives materials from the ER, modifies them, and then sends them out in vesicles.

**Final Answer**: The major site for the synthesis of glycoproteins and glycolipids is the Golgi apparatus (Golgi body).
