the organelles which provide energy for all the activities of a cell are

Options

A. chloroplasts
B. mitochondria
C. golgi bodies
D. ribosomes .

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the organelles in a cell that provide energy for all activities.

2. **Identifying Organelles**: From the video transcript, several organelles are mentioned: chloroplasts, mitochondria, Golgi bodies, and ribosomes.

3. **Analyzing Each Organelle**:
- **Chloroplasts**: These are found in plant cells and are responsible for photosynthesis, which produces glucose. However, they do not directly release energy for cell activities.
- **Mitochondria**: Known as the "powerhouse of the cell," mitochondria convert glucose into ATP (adenosine triphosphate), which is the energy currency of the cell. This means they are directly responsible for providing energy for cellular activities.
- **Golgi Bodies**: Their primary function is to package proteins and lipids for transport within the cell. They do not provide energy.
- **Ribosomes**: These are involved in protein synthesis. While proteins are essential for many cellular functions, ribosomes themselves do not provide energy.

4. **Conclusion**: Based on the analysis, the organelle that provides energy for all activities of a cell is the **mitochondria**.

**Final Answer**: The organelles which provide energy for all the activities of a cell are **mitochondria**.
