Double membrane bound cell organelles of cytoplasm are

Options

A. Chloroplast
B. Mitochondrion
C. both 1 & 2
D. Chloroplast, Mitochondrion and Nucleus

Answer

To answer the question about double membrane-bound cell organelles in the cytoplasm, we can break down the solution step by step:

### Step-by-Step Solution:

1. **Understanding Double Membrane Bound Organelles**:
- Double membrane-bound organelles are those that have two lipid bilayers surrounding them. This structure is crucial for their function within the cell.

2. **Identifying the Organelles**:
- The question asks for examples of double membrane-bound organelles found in the cytoplasm. We need to identify which organelles fit this description.

3. **Chloroplast**:
- The first option is Chloroplast. Chloroplasts are indeed double membrane-bound organelles. They are responsible for photosynthesis, where they convert light energy into chemical energy.

4. **Mitochondrion**:
- The second option is Mitochondrion. Mitochondria are also double membrane-bound organelles. They play a crucial role in cellular respiration, generating ATP, which is the energy currency of the cell.

5. **Nucleus**:
- The nucleus is another organelle that is double membrane-bound. It houses the cell's genetic material and regulates various cellular activities.

6. **Evaluating the Options**:
- The options provided include:
1. Chloroplast
2. Mitochondrion
3. Both 1st and 2nd
4. Chloroplast, Mitochondrion, and Nucleus
- Since all three organelles (Chloroplast, Mitochondrion, and Nucleus) are double membrane-bound, the correct answer is option 4.

### Final Answer:
The double membrane-bound cell organelles of the cytoplasm are **Chloroplast, Mitochondrion, and Nucleus** (Option 4).
