  3. 3. Flowering Plant Characteristics <ul><li>All flowering plants have ____________ tissues used to transport food and water. </li></ul><ul><li>Food moves through the _________ from the leaves down to the roots and stems of the plant. </li></ul><ul><li>Water and nutrients move through the _______ from the roots up to the stems and leaves. </li></ul>vascular phloem xylem
  4. 4. Survival Adaptations <ul><li>Leaves are responsible for _______________ (making food), ______________ (using oxygen to burn food), and _____________ (releasing excess water vapor). </li></ul><ul><li>Stems ____________ the plant, expose the leaves to ________, and transport food and__________. </li></ul><ul><li>Roots __________ the plant and absorb _______ from the soil. </li></ul>photosynthesis respiration transpiration support sunlight water anchor water

  6. 6. Leaves <ul><li>______________ is the process by which plants release excess water to evaporation. </li></ul><ul><li>To regulate transpiration, the plant can open and close its __________. </li></ul><ul><li>[Answer this question] Compare the transpiration process to humans. What could you compare it to? </li></ul>Transpiration stomata
  7. 7. <ul><li>[Answer this question] The stomata also release oxygen and take in carbon dioxide. What human process is this like? </li></ul><ul><li>______________ is the process by which plants burn food to release its energy. </li></ul>Leaves Respiration

  12. 12. <ul><li>The tallest trees in the world, giant redwoods, grow up to 350 tall, but their roots are often only 10 feet deep. </li></ul><ul><li>Redwoods tangle their roots together and give each other strength. They keep one another from falling over because of their own mass. </li></ul><ul><li>What can we as people learn from the redwood trees? </li></ul>Root Facts You don’t have to copy this slide! Just read it and think!
