Green plants are able to convert carbon dioxide and water into oxygen and energy-rich sugars through the process of photosynthesis using sunlight. All living things rely on this process, as it provides the sugars that serve as energy for all other organisms. The document discusses how photosynthesis works on a basic level, noting that carbon dioxide enters leaves and combines with stored energy and chlorophyll through a chemical reaction producing sugar and oxygen. It prompts students to consider what essential thing leaves are deprived of when covered by paper shapes and how the covered areas will appear after a few weeks without that essential component.

4. All living things on our earth rely on green plants for survival. In your journal, explain why this statement is true.

5. Your journal entry should explain that green plants are able to take the energy from the sun and convert it into sugars that are then used as energy by all other living things. This process is called photosynthesis.

6. Carbon Dioxide +Water+Chlorophyll+Sunlight = Oxygen+Sugar CO 2 +H 2 O+Chlorophyll+Energy = O 2 +Sugar Carbon dioxide enters the leaf and combines with stored energy in the chloroplasts through a chemical reaction to produce a simple sugar. Photosynthesis can be described in all of these ways.

7. Look at the paper shapes attached to the leaves of this plant. What essential thing are the leaves being deprived of? What will these leaves look like in a few weeks? Answer in your journal.

8. After a few weeks, the areas of the leaves that were covered will be light green, or even completely white. In order for photosynthesis to take place, green leaves need the sunlight. End
