chondriosome
Definition
Noun: 1. Mitochondrion: A specialized structure (organelle) found within the cells of most eukaryotic organisms, responsible for generating most of the cell's supply of chemical energy (adenosine triphosphate, or ATP) through cellular respiration.
Usage Notes
- Technical/Scientific Term: "Chondriosome" is a largely obsolete, historical term in cell biology. In modern scientific literature, the term "mitochondrion" (singular) or "mitochondria" (plural) is exclusively used.
- Context: You will encounter "chondriosome" primarily in older scientific texts. Using "mitochondrion" is the correct and expected choice in contemporary writing and speech.
Examples
- Noun:
- Early microscopists referred to the energy-producing organelle as a chondriosome.
- The term chondriosome has been replaced by "mitochondrion" in modern biology.
Advanced Usage
- Historical Context: The word "chondriosome" (from Greek , diminutive of 'granule', and 'body') reflects the early observation of these structures as granular bodies within the cell.
