In the plant Arabidopsis thaliana, proteins called photoreceptors help sense the ratio of red to far-red wavelengths of light in the environment. When the environment is shady, the red:far-red ratio is low. If a plant’s photoreceptors detect that the plant is growing in shade, they initiate a change in phenotype called the shade avoidance response. During this response, changes in gene expression result in the plant growing taller and flowering earlier (Figure 1). A diagram of 2 plants in dirt filled containers. The container of the left is labeled bright light and there are green leaves in the container. The container on the right is labeled shade and there are green leaves in the container with a stem coming out of the container and flowers at the top of the stem. Figure 1. An illustration of A. thaliana phenotypes after growth for the same amount of time in bright light and shade. Based on the information above, which of the following statements is true?
