Nematodes are known for 'eutely.' What does this biological phenomenon imply?
Show answer and explanation

Eutely is a condition where the number of cells in the adult body is fixed and constant for a species (e.g., C. elegans). Growth occurs through cell enlargement rather than cell division after embryonic development.
