  1. Careers in Botany and Agriculture Ka Hana ‘Imi Na‘auao – A Science Careers Curriculum Resource Go to: www.cds.hawaii.edu/kahana

  2. Careers: Farming • Cultivating a plant crop • Cabbage, beets, apple, onion, banana, wheat, pumpkin, pine trees (Christmas) etc. • Stewardship of land

  3. Careers: Fishing • Dangerous and demanding • Not just catching fish, also feeding • Responsible not to over fish certain areas • Price rises and falls with market & demand

  4. Careers: Ranching • Raising livestock • Cattle, sheep, porcine, equine • Used for human consumption and recreation • Region specific

  5. Careers: Government • USDA, FDA • DLNR, Forestry Service • Many government agencies dedicated to the preservation and protection of our environment and your safety.

  6. How Plants Work Quick intro to photosynthesis!

  7. Plants are the basis of all life • able to turn materials most organisms cannot use into something they need • through a process called photosynthesis, plants can convert carbon dioxide (CO2) and water (H2O) with the help of the sun and turn it into sugar (C6H12O6) and oxygen gas (O2) • PRETTY AMAZING!

  8. How is it done? • plants use leaves to capture energy from sunlight • like solar panels on your roof to make hot water • inside the leaf there are beads of green organs called chloroplasts • the chloroplasts are able to capture the sun’s energy and uses it to fuel the “magical” stage of photosynthesis

  9. Making Food • after collecting energy from the sun, the plant can now start making sugars • this process of making sugar from water and carbon dioxide was discovered by an American biochemist named Melvin Calvin

  10. Making Food • he found that there was a cycle happening in the plant where it took the energy from the sun to start a cycle of reactions that resulted with sugar • he realized this is the food the plant uses to stay alive • his discovery was later named the Calvin Cycle

  11. Making Food Capture energy from sunlight Fuel Calvin Cycle Makes sugars Steps of Photosynthesis Uses sugar for food or reinforcement (bark, stems, leaves)

  12. At night there’s no sun! • at night when the sun is gone, the plant is still needing energy • so now the plant needs to metabolize something (break a molecule) for energy • the plant stores the sugar it made during the day to use later at night when it needs a snack!

  13. Photosynthetic Equation 6 CO2 +6H2O  C6H12O6 +6O2 • Problem – this doesn’t show the magic of photosynthesis. It gives the ingredients but doesn’t explain how it’s done.
