mitochondrion
This term describes the specialized energy-producing structures within eukaryotic cells. It carries a clinical and scientific connotation, typically appearing in biological textbooks, medical journals, and academic discussions regarding cellular metabolism and genetics.
Because the word originates from Greek, it follows a non-standard English pluralization pattern. Instead of adding a standard s or es, the singular ending on is replaced by a, resulting in the plural form mitochondria. This distinction is critical in scientific writing to differentiate between a single organelle and the collective population within a cell.
Meanings
An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
The mitochondrion is often referred to as the powerhouse of the cell.
