Extra Credit due Tues, Oct 9

This extra credit assignment is due Tues, Oct 9. Each question is worth 20 points. So, you can earn a total of 100 points.

Read the article, "Stalking Plants by Scent." Then, answer these questions:
  1. When the dodder first sprouts, how long can it survive without finding food?
  2. How did scientists test the idea that the dodder can smell?
  3. Why doesn't the dodder grow toward wheat plants?
  4. How can this research help farmers?
  5. What characteristic makes dodders unique compared to other species of plants?
 Answer the questions and then give the paper to me before class on Tuesday.
