Abstract
The effectiveness of stimuli in air depends upon the direction of polarization. For sporangiophores immersed in a medium of refractive index similar to that of the protoplasm this dependence disappears. These facts indicate that one is dealing with simple Fresnel reflection losses and not with dichroism of oriented photoreceptors.Entities:
