The two types of cellular organelles that transform energy are :

Options

A. chromoplasts and leucoplasts
B. mitochondria and chloroplasts
C. mitochondria and leucoplasts
D. mitochondria and ribosomes

Explanation

To answer the question about the two types of cellular organelles that transform energy, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organelles Involved in Energy Transformation**:
- Understand that energy transformation in cells primarily involves specific organelles. The main organelles responsible for energy transformation are chloroplasts and mitochondria.

2. **Chloroplasts**:
- Chloroplasts are found in plant cells and are responsible for photosynthesis. They capture light energy from the sun and convert it into chemical energy in the form of glucose. This process also produces ATP (adenosine triphosphate) through a process known as photophosphorylation.

3. **Mitochondria**:
- Mitochondria are known as the "powerhouses" of the cell. They are found in both plant and animal cells and are responsible for cellular respiration. Mitochondria convert the chemical energy stored in glucose into ATP through a process called oxidative phosphorylation.

4. **Conclusion**:
- The two organelles that transform energy in cells are chloroplasts (which convert light energy into chemical energy) and mitochondria (which convert chemical energy into usable ATP).

### Final Answer:
The two types of cellular organelles that transform energy are **Chloroplasts and Mitochondria**.
