Endomembrane components are
(A) ER (B) Mitochondria
(C) Repository of cell (D) Chloroplast
(E) Suicidal bags of cell

Options

A. A, B, C and D
B. Except 'A' remaining all
C. A, D, E
D. A, C, E

Answer

To determine which components are part of the endomembrane system, we need to analyze each option provided in the question.

### Step-by-step Solution:

1. **Understanding Endomembrane System**: The endomembrane system in a cell consists of various membranes that are either directly connected or communicate with each other. This includes the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vesicles, and the nuclear envelope.

2. **Analyzing Option A: ER (Endoplasmic Reticulum)**:
- The endoplasmic reticulum is a network of membranes involved in protein and lipid synthesis.
- Since it is made up of membranes and is part of the endomembrane system, **this option is correct**.

3. **Analyzing Option B: Mitochondria**:
- Mitochondria are double-membraned organelles known for energy production (ATP).
- They have their own DNA and are not part of the endomembrane system. Thus, **this option is incorrect**.

4. **Analyzing Option C: Repository of Cell**:
- This term is somewhat vague, but if it refers to structures like vacuoles or storage vesicles, they are indeed membrane-bound and part of the endomembrane system.
- Therefore, **this option is correct**.

5. **Analyzing Option D: Chloroplast**:
- Chloroplasts are also double-membraned organelles that contain their own DNA and are involved in photosynthesis.
- Like mitochondria, they are not part of the endomembrane system. Hence, **this option is incorrect**.

6. **Analyzing Option E: Suicidal Bags of Cell (Lysosomes)**:
- Lysosomes are membrane-bound organelles that contain hydrolytic enzymes for digestion and waste processing.
- They are indeed part of the endomembrane system. Thus, **this option is correct**.

### Conclusion:
The components that are part of the endomembrane system are:
- (A) ER
- (C) Repository of cell (assuming it refers to vacuoles or similar structures)
- (E) Suicidal bags of cell (Lysosomes)

**Final Answer**: The correct options are (A), (C), and (E).
