- RER
- SER
- Symplast
- Nucleoplasm
Show Solution
The Correct Option is B
Solution and Explanation
To determine the major site for synthesis of lipids, we need to understand the functions of the cellular components listed in the options:
- Rough Endoplasmic Reticulum (RER): It is primarily involved in the synthesis of proteins due to the presence of ribosomes on its surface. The ribosomes give it a 'rough' appearance.
- Smooth Endoplasmic Reticulum (SER): This is the correct answer. The SER is involved in lipid synthesis, metabolism, and detoxification processes. It lacks ribosomes, which gives it a 'smooth' appearance, and it is the site where lipid synthesis predominantly occurs.
- Symplast: This refers to the network of cytoplasm of different plant cells connected by plasmodesmata. It does not play a major role in lipid synthesis.
- Nucleoplasm: The semi-fluid substance inside the nucleus, containing the chromatin and the nucleolus, primarily involved in cell division and transcription processes, not in lipid synthesis.
The correct answer is SER because it is specifically involved in the biosynthesis of lipids and steroids. The smooth surface of the SER is due to the absence of ribosomes, making it well-structured for lipid synthesis processes.
