This chapter introduces the human visual system and its physiological adaptation to ambient light ranges. This chapter also describes research studies, particularly by Edward Castle and Max Delbrück, conducted on the photo-sensory adaptation of Phycomyces. This chapter states that in Phycomyces a photo-sensory system controls growth and phototropism with ranges of photosensitivity and adaptation comparable to the visual system of humans. The threshold for phototropism and multiplicity of photoreceptive pigments in Phycomyces and plants are also presented.

Keywords:   human visual system, photo-sensory adaptation, Phycomyces, phototropism
