PhotosynthesisBy Jaycie Arndt and Gus Schroth

Raw Materials

• CO2 = Carbon Dioxide = 1 Carbon + 2 Oxygen• H2O = Water = 2 Hydrogen + 1 Oxygen

Step 1

• Carbon Dioxide enters the leaf through the stomata.

Step 2

• Water enters the plant through the roots.

Step 3• Sunlight causes a

chemical change.

Step 4

• Plant produces food for itself. The food is glucose, also known as sugar

Step 5

• Oxygen is released back into the atmosphere.

6 Carbon Dioxide Molecules mix with 6 Water Molecules which combines with light to equal food and 12 Oxygen molecules to be let back into the atmosphere.

Respiration

Definition

• When plants use the stored food for energy.

Comparison of Photosynthesis and Respiration

Photosynthesis Respiration

Occurs in the presence of light Occurs at all times in cells

Requires energy (light) to make sugar (food)

Releases energy from sugar

Sugar is formed from simpler substances Sugar is broken down into simpler substances

Carbon dioxide and water are the raw materials

Carbon dioxide and water are the waste products

Oxygen is given out Oxygen is taken in
