Why does a 6cm carrot have more mass then a 6cm celery?

A 6 cm carrot has more mass than a 6 cm celery because carrots are denser and contain more solid tissue compared to celery, which is primarily composed of water and has a more fibrous structure. The cellular composition and storage of nutrients in carrots contribute to their greater mass. Additionally, carrots are root vegetables, which store energy and nutrients in a compact form, leading to a higher mass at the same length compared to celery stalks.
