1. Cell Energy
All cells need energy to survive. Plant Cells energy comes from the sun and nutrients in the soil. Animal Cells energy comes from food.

2. Photosynthesis Plants have pigments that absorb light.
Chlorophyll is the main pigment that gives the plant its green color.
Chlorophyll is found in Chloroplasts.

3. Plants use the energy captured by chlorophyll to change to carbon dioxide and water into food.
The food is then changed into glucose. ( sugar) The glucose is stored in the plant.
Photosynthesis produces oxygen.

6. Getting energy from food.
There are a couple ways of getting energy from food.
Cellular Respiration- the process by which cells use oxygen to produce energy from food.

7. Most complex organisms (
Most complex organisms (* plants and animals) obtain energy through cellular respiration.
During C. R. food is broken down into CO2 and H2O.
Animals use most energy to maintain body temp.
Some energy is used to form adenosine triphosphate. ( ATP)

8. Prokaryotic Cells-CR takes place in the cell membrane.
Eukaryotic Cells- CR takes place in the mitochondria.
Fermentation- the breakdown of food without the use of oxygen
Two Types:

9. 1. Fermentation happens in your muscles and produce lactic acid.
* This is why your muscle begin to have a burning sensation. ( Muscle Fatigue)
2. Fermentation happens in some types of bacteria and yeast.

10. Connection between Photosynthesis and CR
During photosynthesis cells use CO2 to make glucose and the cell release O2.
During CR cells use O2 to break down glucose and release CO2
