Plants have evolved and acquired the ability to bend towards light. This ability is made possible by a hormone, auxin. Auxin elongates cells on the side of the plant away from the light, thus forcing it to bend towards the light source.
Two students investigated a plant’s ability to bend toward light under several experimental conditions, as shown in Table 1.
Figure 1 illustrates the design of each treatment.
