Rhizophore
rhizophore[′rī·zə‚fȯr] (botany) A leafless, downward-growing dichotomous Selaginella shoot that has tufts of adventitious roots at the apex. Rhizophore one of the slender, rootlike processes formed in Selaginella having prostrate and semiprostrate stems at the branching sites of the stalk. Rhizophores arise in the embryo. In contrast to typical roots, they originate exogenously and have no root cap. Upon reaching the ground, rhizophores form several endogenous suckers that penetrate the soil. Rhizophores are considered organs of stem origin. |
