Which of the following is called the 'powerhouse of the cell' ?
Powerhouse of the Cell Identification
The term 'powerhouse of the cell' is a common analogy used in biology to describe the organelle responsible for generating most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.
Analyzing Cell Components
- Red blood cells: These cells transport oxygen but lack most organelles, including mitochondria. They do not generate cellular energy through respiration.
- Mitochondria: These organelles are known as the sites of cellular respiration, the process that converts glucose and oxygen into ATP. This aligns with the 'powerhouse' description.
- White blood cells: These cells are part of the immune system and, while they are eukaryotic cells containing mitochondria, their primary role isn't energy generation for the entire organism or cell in the same defining way as mitochondria.
- Plasma membrane: This outer boundary controls what enters and exits the cell. It is crucial for cell function but does not generate energy.
Based on their function in energy production through cellular respiration, Mitochondria are universally recognized as the 'powerhouse of the cell'.
