Photosynthesis Reactants and Processes

Where does the original energy for nearly all living things come from?

• Oxygen

• Carbon Dioxide

• The Sun

• Glucose

Put these steps in order:

The Recipe for Photosynthesis

• Carbon dioxide and water combine

• Oxygen is released

• Glucose is formed

• Sunlight absorbed by chloroplasts

Select all that are reactants in photosynthesis.

• Carbon Dioxide

• Water

• Glucose

• Oxygen

Photosynthesis is a __________ reaction because it changes light energy into chemical energy stored in food.

Matter & Energy Movement

• Matter rearranged

• Oxygen and glucose → carbon dioxide and water

• Energy transformed

• Carbon dioxide and water → glucose

• Matter transformed

• Sunlight → chemical energy

How does the Law of Conservation of Mass apply to photosynthesis?
