Resumo

Others thought that they were filled with water and nutrients and conducted sap like veins conduct blood in animals. Archille Richard 1. Richard, A. (1838) Nouveaux Élémens de Botanique et de Physiologie Végétale (6th edn), Béchet Jeune, Paris, France Google Scholar , like many of his contemporaries, was convinced by a simple experiment: he cut a plant segment, dissected it in water and observed many air bubbles trapped in the vessel lumens.
