E.R. is not related with -

Options

A. Plasmalemma
B. Golgibody
C. Mitochondria
D. Nucleus

Answer

To solve the question "E.R. is not related with -", we need to analyze the relationship between the endoplasmic reticulum (E.R.) and the given options. Let's break down the reasoning step by step.

### Step-by-Step Solution:

1. **Understanding Endoplasmic Reticulum (E.R.)**:
- The endoplasmic reticulum is a cellular organelle involved in various functions, primarily protein and lipid synthesis.
- It is divided into two types: Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER).
- RER is studded with ribosomes and is primarily involved in protein synthesis.
- SER lacks ribosomes and is involved in lipid synthesis and detoxification processes.

2. **Analyzing the Options**:
- We need to determine which of the provided options is not related to the functions or processes associated with the E.R.

3. **Option 1: Plasma Membrane**:
- The plasma membrane (also known as Plasma Lama) is composed of lipids and proteins, which are synthesized by the endoplasmic reticulum.
- Therefore, the E.R. is related to the plasma membrane.

4. **Option 2: Golgi Body**:
- The Golgi body (or Golgi apparatus) is involved in modifying, sorting, and packaging proteins received from the E.R.
- Thus, the E.R. is also related to the Golgi body.

5. **Option 3: Mitochondria**:
- Mitochondria are the powerhouse of the cell, primarily involved in cellular respiration and energy production.
- They have distinct functions that are not directly related to the E.R., making this option a strong candidate for being unrelated.

6. **Option 4: Nucleus**:
- The nucleus contains the cell's genetic material (DNA and RNA) and is involved in processes such as transcription and replication.
- The E.R. is related to the nucleus, especially in the synthesis of proteins that are encoded by the genetic material.

7. **Conclusion**:
- After analyzing all the options, we find that the endoplasmic reticulum is not related to the mitochondria. Therefore, the correct answer is **Option 3: Mitochondria**.

### Final Answer:
E.R. is not related with **Mitochondria**.
