1. First exam is MONDAY, NOVEMBER 16 (week 12), and covers LECTURES 1-6.
2. The exam will consist of both multiple choice questions and mini essays. Please bring a #2 pencil for the Scantron form (three points off if you don't bring one!).
20 multiple choice questions, @ 2 points each --> 40 points
4 mini essays, @ 15 points each --> 60 points
TOTAL --> 100 points
Four miniessay topics will be taken from the list below. The other four topics will be covered by multiple choice questions. You are certainly welcome (expected) to prepare these topics ahead of time, but no notes or prewritten essays will be allowed in for the test. These questions can all be answered in 1-2 paragraphs. You will find that much of the material is lecture-based, but your answers will be strengthened by your perusal of the text (or other resources). Please answer all parts of the question(s) asked, but you don't have to be exhaustive for full credit.
1. What are the three vegetative organs of plants? Describe their major aspects, giving at least two examples each from economically useful plants.
2. What is a food chain? Why, generally speaking, can more vegetarians than meat eaters be supported from the same amount of farmed acerage?
