Relating to the chemical composition and chemical reactions that occur within cells.
From Greek 'kytos' (cell) + 'chemical,' from 'chemia' (alchemy). Emerged in early 20th century as researchers began studying cell chemistry with staining and reaction techniques.
Cytochemical staining revealed that different parts of cells contain different chemicals—like finding out that the cell nucleus is full of DNA and RNA through color reactions, before we could actually sequence genes!
