  1. Beechdrops (Epifagus virginiana) are leafless plants that lack chlorophyll. Beechdrops get their nourishment from the roots of beech trees, which reduces the amount of nutrients available to the trees themselves. This interaction is best described as — A. predatory B. parasitic C. commensalistic D. mutualistic

  2. According to this food web, which of these is an omnivore? A. Caterpillar B. Mouse C. Ant D. Fly larva

  3. Which molecule provides most of the energy used to drive chemical reactions in cells? A. DNA B. RNA C. ATP D.ADP

  4. PHOTOSYNTHESIS To create Light Purpose: Plants use light to create sugars (glucose-C6H12O6)

  5. What is photosynthesis? • The process in which plants convert light energy into chemical energy (food glucose). • Happens in the chloroplast

  6. Photosynthesis Equation • PHOTOSYNTHESIS EQUATION: It will be on every quiz and your unit test! Carbon dioxide + water + E → glucose + oxygen 6CO2 + 6H2O + E → C6H12O6 + 6O2 (reactants)(products) light enzymes takesin produces Light Enzymes

  7. Thylakiod: sac like membranes Stroma: space between thylakiods Grana: stack of thylakiods Chloroplast

  8. Within the chloroplast pictured above are disc like structures arranged in stacks called grana. The stack like membranes contains pigments that absorb light energy. The individual disc-like shaped structures labeled A are called ____. A. chlorophyll B. thylakoids C. stroma D. Golgi apparatus A B

  9. Which word summary word equation best describes a process that directly requires light energy? A. water + carbon dioxide  glucose + oxygen B. glucose + glucose  maltose + water C. glucose  alcohol + carbon dioxide + ATP D. water + glucose  oxygen + carbon dioxide  ATP

  10. Vein

  11. Water enters the plant through the roots and travels up to the leaf through the veins. Water then travels to each cell through a process known as OSMOSIS.

  12. Stomata Stomata are the little “holes” on a plant leaf that regulates the gas exchange in plants.

  13. Carbon dioxide enters the leaf through the stomata. Carbon dioxide then travels to each cell through a process known as Diffusion.

  14. Which structure regulates gas exchange during the processes of photosynthesis and respiration? A. Q B. R C. S D. T

  15. Products and Reactants in Photosynthesis • Reactants- Carbon Dioxide and Water • Products- Glucose and Oxygen • There is NO ATP gain during photosynthesis! • *****Remember the ATP Cycle*****

  16. Light and Pigments • Photosynthesis depends onpigments -proteins that absorb some light and reflect others. • Examples: chlorophyll and carotene

  17. Light and Pigments • Chlorophyll absorbs blue, violet, and red light, but reflects green light. • This is why plants are green. • Carotene reflects orange light.

  18. Which compound is a product of photosynthesis and a reactant for cellular respiration? A. carbon dioxide B. water C. glucose D. energy

  19. Why are photosynthesis and cellular respiration often considered opposites? A. Photosynthesis produces twice as many ATP molecules as cellular respiration does. B. Water is released during photosynthesis and consumed during cellular respiration. C. Photosynthesis occurs during the day, and cellular respiration occurs at night. D. Oxygen is produced during photosynthesis and used during cellular respiration

  20. BIG PICTURE • Plants release oxygen • Animals bring in oxygen • Plants create glucose • Animals eat glucose • Animals breathe out water • Plants bring in water

  21. Oxygen Glucose Carbon Dioxide water BIG PICTURE • Plants and animals work together to create the carbon cycle:
