Botany of Herbal Plants 1 Plant Morphology: Roots and Stems Botany of Hebal Plants 1 Dr.Rumrada Meeboonya www.shalom-education.com Roots The Basic Plant Organs Roots  The primary root or tap root, originating from radicle in the seed embryo to emerge from a germinating seed. It soon branches to form lateral roots. ROOTS  Adventitious roots arise from the other organs (stems, leaves).
