2. Human resource production and use Worldwide Grain Production and Consumption http://www.earth-policy.org/Indicators/Grain/2006.htm

3. We can now directly insert new genes into or modify existing genes of plants CB 20.2

4. Why Change a Plant’s DNA? • Can change plant so that it has new or different characteristics • Produce needed protein • Insect resistance (Bt toxin) • Herbicide resistance (Round-up) • Drought or other stress resistance • Chemical remediation

5. Is genetically engineering plants a good idea? Worldwide area planted with genetically modified crops Texas =70 ha Millions of Hectares http://www.gmo-compass.org/eng/agri_biotechnology/gmo_planting/257.global_gm_planting_2006.html

6. Is changing a plant’s DNA a good or bad idea? • Genes flow within species and between species. • Are GM foods safe for the environment? • Are GM foods profitable for: • Consumers, Farmers, and Companies?

7. Pollution in Gulf of Mexico from run-off in the Mississippi river ‘07 http://blog.nola.com/times-picayune/2007/06/despite_promises_to_fix_it_the.html(Staff graphic by Dan Swenson)

8. Pollen is easily transferred from plant to plant, and to related species.

9. Genetic information moves. GM crops found in Oaxaca and other MX states GM crops illegal

10. Genetic information moves, and is self-replicating. GM crops found in Oaxaca and other MX states GM crops illegal

11. Is changing a plant’s DNA a good or bad idea? • Genes flow within species and between species. • Are GM foods safe for the environment? • Are GM foods profitable for: • Consumers, Farmers, and Companies?

12. Types of Genetically Modified Crops Herbicide Tolerance; Insect Resistance; Viral Resistance

13. Monsanto stock price: 3/24/08 at 12:30pm= $106

14. Grain farmer claims moral victory in seed battle Ten years after he took on the multinational Monsanto, Saskatchewan man gets $660 and the right to talk about it http://www.theglobeandmail.com/servlet/story/LAC.20080320.FARMER20/TPStory/National

15. The Schmeisers' saga began more than 10 years ago, when Monsanto sued them after plants grown from genetically modified canola seeds were found on the couple's farm near Bruno, Sask., about 90 kilometres east of Saskatoon. The company said the Schmeisers violated its patent on the seeds, which had been genetically modified to resist Monsanto-brand herbicide, and that the couple knowingly planted them without paying the technology fees. Monsanto's claim sought damages totalling $400,000. http://www.theglobeandmail.com/servlet/story/LAC.20080320.FARMER20/TPStory/National

16. But the Schmeisers denied using the Monsanto seeds, arguing that the seeds blew onto their property from a nearby road or neighbouring farms. In 2004, the Supreme Court ruled 5-4 in favour of Monsanto, stating that plant genes and modified cells can be patented. Although the Schmeisers lost the case, the court ruled they did not have to pay damages. http://www.theglobeandmail.com/servlet/story/LAC.20080320.FARMER20/TPStory/National

17. Grain farmer claims moral victory in seed battle Ten years after he took on the multinational Monsanto, Saskatchewan man gets $660 and the right to talk about it The following year, more of the genetically modified canola appeared on the Schmeisers' farm. They pulled it out themselves and sent Monsanto a bill for $660. http://www.theglobeandmail.com/servlet/story/LAC.20080320.FARMER20/TPStory/National

18. Many Questions, but Few Answers? • Genes flow within species and between species. • Are GM foods safe for the environment? • Are GM foods profitable for: • Consumers, Farmers, and Companies?

19. Life as we know it… the animals CB 26.22

20. One important consideration of structure and function…surface area Nalca leaves http://www.celebratebig.com/chile/index3.htm

21. One important consideration of structure and function…surface area CB 40.3

22. CB 40.4 Why is surface area so critical? Animals (and plants) must exchange various components with the environment

23. Organisms are organized:atomsmoleculesorganellescellstissuesorganssystems organisms

24. Four major tissue types in animals:epithelial, connective, muscle, and nervous

25. Epithelieal tissue: Covers and lines body and/or parts. Tightly packed cells. CB 40.5

26. Connective tissue: Holds and supports. Few cells with an extensive extracellular matrix. CB 40.5

27. Muscle tissue: Movement. Long muscle fibers cells. CB 40.5 Nerve tissue: Signaling. Generally long cells, neurons.

28. Different tissues that comprise the stomach, an organ. CB 40.6

29. Homeostasis: Maintaining a steady-stateinternalcondition CB 40.11
