Sažetak

Photomovement, taken in its broader sense, comprises the responses of motile organisms, intracellular movement, phototropic curvature, and photonastic movement. These responses can be scalar or vectorial with respect to the light direction. For classifying scientific questions, a schematic sequence can be defined, viz. perception - signal transduction - terminal response. In this paper, the present state of knowledge is summarized for selected systems exemplifying various types of response. This is intended to provide the background for future scientific questions that appear important and promising to be investigated. Although the modern genetic and molecular approaches are most essential for progress, they have to be based on well-established and sound results from »classical« physiology.
