Points to Remember:
- The question tests knowledge of cell biology and the functions of different organelles.
- The correct answer will identify the organelle primarily responsible for ATP production.
Introduction:
Cells are the fundamental units of life, and their proper functioning depends on the coordinated activities of various specialized structures called organelles. Each organelle plays a specific role in maintaining cellular homeostasis. The question asks to identify the organelle nicknamed the “powerhouse” of the cell, referring to its crucial role in energy production. This energy, primarily in the form of ATP (adenosine triphosphate), fuels most cellular processes.

Understanding Cellular Organelles:
To answer the question correctly, we need to understand the functions of the organelles listed:
Golgi Apparatus: The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles within the cell. It is not directly involved in energy production.
Ribosomes: Ribosomes are responsible for protein synthesis. They translate the genetic code from mRNA into polypeptide chains, which then fold into functional proteins. While protein synthesis requires energy, ribosomes themselves don’t generate it.
Mitochondria: Mitochondria are double-membraned organelles often referred to as the “powerhouses” of the cell. They are the primary sites of cellular respiration, a process that converts nutrients into ATP, the cell’s main energy currency.
Lysosomes: Lysosomes are membrane-bound organelles containing digestive enzymes. They break down waste materials, cellular debris, and ingested substances. They are not involved in energy production.
Analysis of Options:
Based on the functions described above, only the mitochondria directly generate ATP, the cell’s primary energy source. Therefore, the other options are incorrect.
Conclusion:
The correct answer is (C) Mitochondria. Mitochondria are rightly called the “powerhouses” of the cell because they are responsible for the majority of ATP production through cellular respiration. This energy is essential for all cellular processes, from muscle contraction to protein synthesis and cell division. Understanding the functions of different organelles is crucial for comprehending the complexity and efficiency of cellular processes, highlighting the intricate design of life at the cellular level. Further research into mitochondrial function is vital for understanding and treating various diseases linked to mitochondrial dysfunction.
