Answer:

Explanation:

Phototactic responses are observed in many organisms such as Serratia marcescens, Tetrahymena, and Euglena.

Chemotaxis (from chemo- + taxis) is the movement of an organism in response to a chemical stimulus. Somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.
