The double membrane bound, sausage shaped cell organelle found in more numbers in activity dividing cells is

Options

A. chloroplast
B. mitochondria
C. ribosomes
D. nucleus

Answer

To solve the question, we need to identify the cell organelle that is double membrane-bound, sausage-shaped, and found in greater numbers in actively dividing cells. Let's break down the solution step by step:

### Step-by-Step Solution:

1. **Understanding the Question**:
- We are looking for a cell organelle that has a double membrane, is sausage-shaped, and is more abundant in cells that are actively dividing.

2. **Analyzing the Options**:
- **Option 1: Chloroplast**:
- Chloroplasts are involved in photosynthesis and are not typically described as sausage-shaped. They also do not fit the criteria of being more abundant in dividing cells.
- **Option 2: Mitochondria**:
- Mitochondria are indeed double membrane-bound organelles. They have an inner and outer membrane and are often described as having a sausage-like shape. They are crucial for energy production (ATP) and are found in higher numbers in cells that are actively dividing due to their energy demands.
- **Option 3: Ribosomes**:
- Ribosomes are not membrane-bound and are involved in protein synthesis. They do not fit the description given in the question.
- **Option 4: Nucleus**:
- The nucleus is a membrane-bound organelle that regulates cell activities, but it is not typically described as sausage-shaped and does not fit the criteria of being more abundant in dividing cells.

3. **Conclusion**:
- Based on the analysis of the options, the correct answer is **Option 2: Mitochondria**. They are double membrane-bound, sausage-shaped, and found in greater numbers in actively dividing cells due to their role in energy production.

### Final Answer:
The double membrane-bound, sausage-shaped cell organelle found in more numbers in actively dividing cells is **Mitochondria**.
