Plantsssssss

  1. 1. Plants<br />Birth to death, we need plants<br />Commonly overlooked but should be respected<br />They will be our saviors<br />Species variability is important to humans<br />They are not just food<br />They are our friends<br />
  2. 2. Plants and us<br />This powerpoint minimally explains how<br />. plants benefit us as humans<br />. photosynthesis works<br />. roots have adapted to different soils<br />
  3. 3. Our plants<br />. filter the atmosphere of pollutants<br />. supply us with the oxygen we need<br />. translate energy from the sun<br />. feed ourselves and our livestock<br />. support vital ecosystem services<br />. utilizing light, CO2, water and minerals<br />Los padres on national forest by Chuck the Photographer June 3, 2008<br />
  4. 4. Photosynthesis<br />
  5. 5. Plant mass<br />. Plant mass originates from photosynthesis<br />. Plant mass is accumulated minerals<br />. Plant mass is sugars<br />. The actual mass is mostly water<br />
  6. 6. Factors affecting plant mass<br />Nutrient availabilty<br />Ph level 5.5-7.5 typically<br />Elevated CO2 means more mass<br />Ventilation, air flow <br />Intensity of light hitting plant<br />Proper moisture levels within soil<br />
  7. 7. Sugars stored after photosynthesis<br />. plants store sugars for later use<br />. plants use their sugars for structure<br />. these sugars are the plant’s nutrition<br />
  8. 8. Plants and their vital role<br />…Plants provide our livestock with food<br />… Plants convert sunlight into sugars<br />… sugars are edible to bugs/animals<br />… we eat these plants or animals<br />Los padres on national forest by Chuck the Photographer June 3, 2008<br />
  9. 9. Houseplants<br />… are awesome friends<br />… fill the house with oxygen<br />… can yield a variety of herbs<br />… provide a healthy hobby<br />… give chosen seeds a good life<br />
  10. 10. Plants grown in low CO2 conditions: <br />... quickly become spindly and lack vigor<br />… won’t yield fruit, flowers or buds <br />… exhibit larger susceptibility to pests/disease<br />… often die<br />
  11. 11. Roots<br />Search out nutrients for <br /> the plant<br />Find water for the plant<br />Provide a fixed base for stem<br />Can also strangle other plants roots<br />Roots<br />Roots<br />Roots<br />Roots<br />Roots<br />Roots<br />Roots<br />Roots<br />
  12. 12. Root types<br />Plants have evolved many root types<br />Differing moisture conditions caused this<br />almost all roots share a purpose<br />Most roots also require oxygen<br />
  13. 13. The taproot<br />Commonly seen as a carrot<br />Is a huge central root<br />Many smaller hair roots extrude<br />Common in dense <br /> rooting situations<br />
  14. 14. The adventitious roots<br />Burst explosive growth in all directions<br />Are very fibrous<br />Extremely prolific in consuming space<br />Will continue to search <br /> for nutrients<br />Anchor the plant firmly<br />Come straight from a<br /> stem<br />
  15. 15. The fibrous root<br />Comes off of other roots<br />Becomes very, very thin<br />Less than 1mm in some cases<br />Large surface area means maximum absorption<br />Low mass for maximum saturation potential<br />
  16. 16. Roots in general<br />The bigger the root system…<br />The more powerful the plant <br />More roots means more water & nutrients<br />Super healthy roots are bright white<br />
