8. Two important processes that cells use are photosynthesis and cellular respiration. Describe these two processes. SELECT ALL THAT APPLY

• photosynthesis is the process used to obtain energy from the sun. It makes food for plants. 6CO2 + 6H2O + light energy --> C6H12O6 + 6O2

• Cellular respiration: breaks down food and stores energy. It releases carbon dioxide. C6H12O6+6O2---> 6CO2+6H2O+ATP

• Photosynthesis: breaks down food and stores energy. It releases carbon dioxide. C6H12O6+6O2---> 6CO2+6H2O+ATP

• Cellular respiration is the process used to obtain energy from the sun. It makes food for plants.6CO2 + 6H2O + light energy --> C6H12O6 + 6O2

• All of the above.

9. The picture shows the process of photosynthesis.One of the products of photosynthesis is not shown in the diagram.

What is the missing product? Describe the role of this substance in plant cells. Answer both parts in one complete sentence.

Answer explanation

The Missing product is gluecose (C6H12O6). Sugar is used in life processes for the plant.

10. Fossil fuels come from decomposed plants and animals that were buried in the ground millions of years ago.

Explain why burning fossil fuels releases carbon dioxide. SELECT ALL THAT APPLY.

• Plants and animals died and decomposed and were eventually buried. over time they became fossil fuels.

• The bodies of living organisms are made up of carbon molecules such as sugars.

• It does not release carbon dioxide into the atmosphere.

• None of the above.
