structure is the primary source of energy for cells?

Mitochondria
Ribosomes
Nucleus
Golgi apparatus

The correct answer is: Mitochondria

Mitochondria are considered the primary source of energy for cells because they are the site of cellular respiration, which produces the molecule ATP that is used as energy currency in cells. Ribosomes are responsible for protein synthesis and do not produce energy. The nucleus houses DNA and acts as the control center of the cell, but it does not directly produce energy. The Golgi apparatus is involved in processing and packaging proteins, but it does not generate energy. Therefore, the best answer is mitochondria as it directly produces energy for cells.
