Photosynthesis Photosynthesis Presentation Transcript

  • Photosynthesis
  • Uses light energy to make food (glucose) in plants Equation for Photosynthesis 6CO 2 + 6H 2 O + Sunlight C 6 H 12 O 6 + 6O2 Carbon dioxide + water + sunlight glucose + oxygen
    • Occurs in green leaves
    -The leaves have cells that contain Chloroplasts -Chloroplasts contain a green pigment called chlorophyll Chlorophyll has the ability to change light energy into chemical bond energy Chlorophyll absorbs red and blue light and reflects green light. chloroplast
  •  
  • Chlorophyll – pigment in chloroplasts
    • Two types: chlorophyll a and chlorophyll b
    • Absorb red and blue light
    • Reflect Green light
    • Having both a & b enable plants to absorb light from a wider region of the spectrum
    • What color light would be best for plants to grow in?
    • Red & Blue
  • Photosynthesis only occurs in the light. Provides most of the oxygen in our atmosphere. The rate of photosynthesis depends on: Temperature ( ENZYMES ) Light Intensity Amount of CO 2 available Amount of Water available
  • Photosynthesis is the opposite of cellular respiration
    • Photosynthesis
    • Occurs in Chloroplasts
    • Energy Storage
    • Uses: CO 2 + H 2 O + light energy
    • Makes: C 6 H 12 O 6 (glucose) + O 2
    • Aerobic Respiration
    • Occurs in Mitochondria
    • Energy Release
    • Uses: C 6 H 12 O 6 (glucose) + O 2
    • Makes: CO 2 + H 2 O+ chemical energy (ATP)
  • Cellular Respiration
