How do diatoms perform respiration?

Diatoms perform respiration by taking in oxygen and releasing carbon dioxide through a process known as cellular respiration. This occurs in their mitochondria, where organic compounds produced during photosynthesis are broken down to release energy. In addition to respiration, diatoms utilize photosynthesis to convert light energy into chemical energy, allowing them to thrive in various aquatic environments. This dual capability supports their growth and energy needs.
