Presentation Transcript

  1. Photosynthesis and Respiration Unit: Plant Science

  2. Five plant processes • Photosynthesis • Respiration • Water Absorption • Translocation • Transpiration

  3. Movement of Nutrients and Water • Transpiration • Translocation • Absorption

  4. Movement of water and nutrients • Transpiration • Loss of water by evaporation through the leaf surface • Occurs when the stoma open to take in CO2

  5. TRANSPIRATION

  6. TRANSPIRATION

  7. Movement of water and nutrients 2. Translocation a. movement of water and organic compounds within the plant

  8. XYLEM and PHLEOM

  9. Movement of water and nutrients 3. Absorption a. nutrients absorbed through root hairs b. Osmosis occurs by diffusion c. Diffusion is the movement of molecules from high concentration to low concentration

  10. Absorption

  11. Photosynthesis • Process through which green plants convert carbon dioxide and water in the presence of light into simple sugar

  12. Photosynthesis

  13. Photosynthesis

  14. Plants use food for…. • Energy • Plant growth • Store food • Respiration

  15. Energy http://www.indiana.edu/~oso/animations/potato.html

  16. Plant Growth http://www.indiana.edu/~oso/animations/ginkgogrowth.html

  17. Respiration • Breakdown of glucose • C6H12O6 + 6O2 6CO2 + 6H2O + energy • Releases Carbon dioxide and water into the air • Aerobic respiration- presence of oxygen • Anaerobic respiration- without oxygen

  18. Air Quality • Plants release oxygen into the atmosphere • Plants absorb carbon dioxide from the atmosphere

  19. REVIEW FOOD GLUCLOSE
