1. Mitochondria: These are often called the "powerhouses" of the cell. They take chemical energy stored in glucose (sugar) and convert it into a usable form of energy for the cell called ATP (adenosine triphosphate). This process is called cellular respiration.
* Energy transformation: Chemical energy (glucose) → Chemical energy (ATP)
2. Chloroplasts: These organelles are found in plant cells and some protists. They use light energy from the sun to convert carbon dioxide and water into glucose (sugar) and oxygen. This process is called photosynthesis.
* Energy transformation: Light energy → Chemical energy (glucose)
Let me know if you'd like more details about either of these organelles!
