Next, the researcher wanted to determine if the timing of the flash of ight, whether It was early or late into the dark perlod, had an affect on the flowering plants. The researcher exposed Xanthlum strumarlum plants to a cycle of 12 hours light/12 hours dark and exposed the plants to a 10 minute burst of light at different times within the dark perlod. She recorded the percent of flowering plants post exposure. The data is in the chart below. 6. What conclusions can you draw from this data? (You do not need to show a graph, but it may help with your answer.) * % of plants flowering Time of burst of light (from the beginning of dark period) 100 86 35 41 10 78 12 95 21 4- 8.

A short-day plant flowers only when exposed to light for less than 12 hours long. Which of the following would cause the plant to flower? * O a 13-hour night and 11-hour day with 1 minute of darkness after 6 hours a 12-hour day and 12-hour night with a flash of red light an 8-hour day and 16-hour night with a flash of white light after 8 hours O a 9-hour night and 15-hour day with 1 minute of darkness after 7 hours 24 hours of continuous light
