What is the primary function of mitochondria in cells?

Photosynthesis
Cell division
Powerhouse of the cell
Protein synthesis

The correct answer is: Powerhouse of the cell

The primary function of mitochondria is to serve as the powerhouse of the cell, which is reflected in the choice that identifies this role. Mitochondria are essential organelles known for their role in energy production through the process of cellular respiration. They convert nutrients from the food we eat into adenosine triphosphate (ATP), the form of energy that cells can readily use to power various biological processes. Mitochondria also participate in other important functions, such as regulating cellular metabolism, maintaining calcium homeostasis, and controlling programmed cell death (apoptosis). However, their most recognized role as the powerhouse of the cell emphasizes their critical contribution to energy production, making this answer the most appropriate choice among the options provided. Other answers, while related to cellular processes, do not accurately capture the essential function of mitochondria.
