Berkmar Botany 4/11/07

  1. 1. Berkmar Botany By: Catherine Johnson
  2. 2. Plant Kingdom <ul><li>As you very well know, we are different from plants. But did you know: </li></ul><ul><li>98% of biomass (life-space) comes from plants. </li></ul><ul><li>The second largest “tradable” item comes from a plant, which is coffee. </li></ul><ul><li>The stems of sunflowers used to be stuffed into lifejackets. </li></ul>
  3. 3. Photosynthesis <ul><li>Photosynthesis is usually hard to explain, but it is basically using light to make food. (keyword: </li></ul><ul><li>photo=light, synthesis=making. </li></ul><ul><li>Light + making =photosynthesis) </li></ul><ul><li>This is how most of the plants at Berkmar make their sugar, which is like life support from a machine </li></ul><ul><li>(with wheels). </li></ul>
  4. 4. Vascular vs. Non Vascular <ul><li>Vascular- </li></ul><ul><li>Plants that contain a transport system that could move fluids. They contain xylem and phloem. Xylem carries inorganic stuff and water to the top of the roof. Phloem carries organic things like sugar throughout the plant. </li></ul><ul><li>Ex: Ferns, Club Mosses, flowers, or celery. </li></ul><ul><li>Non Vascular- </li></ul><ul><li>Plants that don’t contain a transport system. Although they don’t have a vascular system, they still transport their materials through the water. That is why they dwell in damp, shady areas, where water doesn’t dry out. </li></ul><ul><li>Ex: Algae, Moss, </li></ul><ul><li>or Hornworts </li></ul>
  5. 5. Bradford Pear tree <ul><li>The scientific name for a bradford pear tree is Pyrus calleryana, or the callery pear tree. To many people it is known for it’s unpleasant smell. (My brother says it smells like fish!) Its fruit looks like a olive/golden brown marble, and it is good for surviving in the sun. In autumn, their leaves turn a brilliant shade of red/scarlet. </li></ul>
