Serrated means having a row of small teeth along the edge. A serrated knife, serrated leaves, serrated edges.
A serrated blade cuts by sawing rather than by pressing, which is why it works on bread and tomatoes and why it cannot be sharpened at home. In botany a serrated leaf has teeth pointing forwards, and the shape helps identify a species.
