Acetabularia

a genus of marine algae. Individuals may reach a size of 30 mm and are ACELLULAR with a body consisting of three distinct areas: head, stalk and a base containing the single NUCLEUS. Experiments by the German biologist Joachim Hammerling (b. 1901) using grafts between two species demonstrated that the nucleus alone is responsible for body morphology and produces a chemical substance which can control development. Such results cannow be interpreted as indications of the role of DNA and MESSENGER RNA.

Van Wijk y Van Wijk (23) demostraron que si se colocaba una muestra de Acetabularia cerca de un curandero y su paciente, y median la emision de fotones del alga durante la sesion de curacion y durante los periodos de descanso, se producian alteraciones marcadas en el contaje de los fotones emitidos por el alga, asi como cambios en el ritmo de las emisiones, como si el alga se encontrara en armonia con una fuente mas poderosa de luz.
