Phototaxis. the motor reaction of motile microorganisms in response to the stimulus of light; a form of taxis. The reaction of zoospores to light, and the slow shift of chloroplasts within a cell in response to light, are also called phototaxis.
As defined above, haptotaxis is the motility of cells up a gradient of substrate bound molecules. There is a wide variety of procedures to set up this gradient in vitro for the study of haptotaxis.
