Presentation Transcript

  1. Chapter 6Photosynthesis

  2. autotroph • An organism that can make its own food • Includes plants, algae, some protists, and some bacteria

  3. photosynthesis • The process of converting sunlight to chemical energy

  4. Equation for photosynthesis Carbon dioxide + water yields glucose + oxygen

  5. heterotroph • An organism that obtains its nutrition by eating other organisms

  6. ATP • An energy storing molecule; stores chemical energy produced from photosynthesis Energy is released from ATP when a phosphate group is broken off.

  7. chloroplast • A structure found in plants; where photosynthesis occurs

  8. thylakoid • Membrane of grana where first stage of photosynthesis takes place; light energy is absorbed

  9. grana • Structures in the chloroplast that are the site of photosynthesis; (a stack of thylakoids)

  10. chlorophyll • A green pigment that absorbs certain wavelengths of light

  11. pigment • Compounds that absorb light

  12. carotenoid • Compounds that are accessory pigments (they help chlorophyll) • Absorb wavelengths of light that chlorophyll can’t • Produce yellow, orange and brown colors

  13. stomata • Holes in plant leaves that take in CO2 and give off O2 and water

  14. stroma • Solution in the space around the grana (pl.) • Granum (s.)

  15. photosystem • Cluster of pigment molecules in thylakoid membrane
