3 7. Which plant was the tallest at the end of the 20-day period? *Base your answers to questions 7 – 11 on the information and graph below.A gardener performs an experiment growing three types of plants in equal amounts of soil. Threedifferent types of plants are used. Each plant is 10 centimeters tall at the beginning of the experiment.The three plants are given 4 milliliters of water every day for 20 days. The results of the experimentare shown on the graph.7. Which plant was the tallest at the end ofthe 20-day period?8. Other than at the beginning of theexperiment, on what day were plant 2 & 3the same height? __________9. Which plant grew at the slowest ratefrom day 0 to day 5? _________10. During which time interval did plant 1 become taller than plant 3?(1) days 0– (3) days 5–10(2) days 10– (4) days 15–20PLANT 2DAY 16PLANT 111. The gardener repeated the experiment using identical conditions. Plant 1 grew the fastest. Suggest onechange to the experimental design that would help the gardener decide which plant really grows fastest._____________________________________________________________________________________START WITH SEEDS BECAUSE THE PLANTS WERE ALREADY10 CM TALL IN THE FIRST EXPERIMENT.
4 DARK AREA = NO SUN = NO P.S. = NO SUGAR 12. The diagram below shows a leaf that has been partially covered with black paper for three days.When the black paper is removed, the area that wascovered by the paper has turned white. The white sectionof the leaf tests negative for the presence of sugar and thegreen section tests positive for the presence of sugar.Explain why the white and green sections of the leaf havedifferent sugar test results._____________________________________________________________________________________THE WHITE SECTION DID NOT MAKE ANY FOOD BECAUSE IT DID NOT RECEIVE ANY LIGHT. THE GREEN SECTION DID PERFORM PHOTOSYNTHESIS AND MADE SUGAR.ORDARK AREA = NO SUN = NO P.S. = NO SUGAR
