2 19 Photosythesis & Leaves

  1. 1. Leaves & Photosynthesis Plant: Hyacinth Term: Photosynthesis
  2. 2. Hyacinth <ul><li>Plant type: Interior Plant, Perennial </li></ul><ul><li>USDA Hardiness Zones: 6a to 9a </li></ul><ul><li>Height: 9&quot; to 12&quot; Spread: 3&quot; to 5&quot; </li></ul><ul><li>Exposure: partial shade to full sun </li></ul><ul><li>Blooms Color: Early to Mid spring, Blue, Pink, Purple, Red, White, Yellow </li></ul><ul><li>Soil: dry to moist, Loamy, Neutral, Well drained </li></ul><ul><li>Uses: Borders, forced potted plant, cut flower. </li></ul><ul><li>Extremely fragrant </li></ul><ul><li>Grows from bulbs – has vernalization requirement </li></ul>
  3. 3. Photosynthesis <ul><li>The process of converting energy from the sun and Carbon dioxide from the atmosphere into glucose (food). </li></ul><ul><li>Photosynthesis </li></ul><ul><li>Respiration – the OPPOSITE of photosynthesis </li></ul><ul><ul><li>Carbohydrate + Oxygen + Water -> </li></ul></ul><ul><ul><ul><li>Water + Carbon Dioxide + Energy </li></ul></ul></ul><ul><li>Plants photosynthesize & respire </li></ul>
  4. 4. C 3 & C 4 Photosynthesis <ul><li>Two kinds of photosynthesis: C 3 & C 4 </li></ul><ul><ul><li>C 4 Plants photosynthesis more rapidly than C 3 </li></ul></ul><ul><ul><li>C 4 Plants can photosynthesize at hotter temperatures and brighter light than C 3 </li></ul></ul><ul><ul><li>C 4 Plants use CO 2 more efficiently than C 3 Plants. </li></ul></ul><ul><li>C 4 Plants are better suited to warm & tropical climates </li></ul><ul><li>C 3. Plants are better suited to more temperate areas </li></ul>
  5. 5. Leaf Functions <ul><li>Photosynthesis </li></ul><ul><ul><li>Food Manufacture </li></ul></ul><ul><ul><li>Only in leaves & stems (Green parts) </li></ul></ul><ul><li>Respiration </li></ul><ul><ul><li>Opposite of photosynthesis </li></ul></ul><ul><ul><li>Necessary for growth </li></ul></ul><ul><ul><li>All plant cells </li></ul></ul><ul><li>Transpiration </li></ul><ul><ul><li>Water control </li></ul></ul>
  6. 6. Leaf Anatomy <ul><li>Stomata – pore openings in the epidermis </li></ul><ul><li>Control water & gas flow </li></ul>
  7. 7. Chloroplasts & Chlorophyll <ul><li>Site of photosynthesis </li></ul><ul><li>Light phase </li></ul><ul><ul><li>Sunlight to ATP </li></ul></ul><ul><li>Dark phase </li></ul><ul><ul><li>ATP to glucose </li></ul></ul>
  8. 8. Leaf Arrangements
  9. 9. Leaf Shapes
  10. 10. Leaf Margins
  11. 11. Why is it important? <ul><li>Leave shapes, margins, and arrangements are used to identify unknown plants. </li></ul><ul><li>ID keys take you step by step through the leaf arrangement until you have found the right plant </li></ul><ul><li>Common Trees of Va. book </li></ul>
  12. 12. Fast Plants Seeds <ul><li>Start Fast Plants </li></ul><ul><li>Everybody gets 6 seeds </li></ul><ul><li>1 Petri Dish </li></ul><ul><li>Person with the highest seed production at the end of the lifecycle gets a Subway gift card. </li></ul>
