A longitudinal section and a cross-section of corn roots

Caption

A longitudinal section and a cross-section of corn roots showing perforation plates within the metaxylem vessels and metaxylem vessel element length are shown in these images generated by cryo-scanning electron microscopy. Long, smooth vessels conduct faster flow, creating a more efficient water-transport system, the researchers reported.
