We are going to investigate the affects of two of those hormones on the growth of radish seeds. This experiment will also investigate the phenomenon of geotropism. A tropism is a growth response of a plant to an environmental influence. Phototropism is the typical growth of plants toward light that most of you have seen. This phenomenon is introduced in your textbook where the discovery of plant hormones is discussed. A response to gravity is also obvious—even with no labeling instructions, you will manage to plant seed such that the root grows and the stem grows up.
