Presentation Transcript
slide2

Energy cannot be created or destroyed, it can only be transformed

  • All organisms need carbohydrates for energy conversion
slide4

Glucose C6H12O6is a carbohydrate

  • Autotrophs are capable of making their own carbohydrates
  • Heterotrophs are not capable of making their own carbohydrates and therefore must get them by some other means
slide7

Carbohydrates are made in the chloroplast in a process called photosynthesis

  • Plants and other photosynthetic organism are green because they contain the pigment chlorophyll
slide8

Light from the sun contains all the colors of the spectrum (rainbow).

Chlorophyll absorbs all the colors except for green.

The wavelength of light that is green is reflected. That is why we see plants as green

slide11

Photosynthesis: Plants use the energy from sunlight to convert water (H2O) and carbon dioxide (CO2) into high-energy carbohydrates

photosynthesis equation
Photosynthesis Equation:
  • 6CO2 + 6 H2O -> C6H12O6 + 6 O2

Sunlight
