Why is the process that takes in a mitocondrion often described as being the opposite of the process that takes place in a chloroplast?

The processes in mitochondria and chloroplasts are often described as opposites because they perform complementary roles in energy transformation. Mitochondria carry out cellular respiration, converting glucose and oxygen into ATP while releasing carbon dioxide and water as byproducts. In contrast, chloroplasts conduct photosynthesis, using sunlight to convert carbon dioxide and water into glucose and oxygen. Thus, the outputs of one process serve as the inputs for the other, highlighting their interdependent nature in cellular metabolism.
