Photosynthesis NGSS

Which of the following best summarizes photosynthesis?

• A chemical reaction involving nitrogen and other atmospheric gases

• An adaptation of plants that allows them to add nutrients to the soil

• A chemical reaction in which plants produce sugar using the energy of sunlight

• An exchange of gases between animals and the air or water of their habitat.

The concentration of carbon dioxide in parts per million (ppm) was measured for a closed container in several situations. Which of the following data collected would demonstrate the action of photosynthesis?

• When multiple plants were put into the container, carbon dioxide concentrations never got above 1,000 ppm.

• As the temperature in the container increased, the carbon dioxide concentrations went from 800 to 1,000 ppm.

• Plants in the container kept in darkness did not lower the concentration of carbon dioxide below 800 ppm.

• When the container included a plant exposed to light, carbon dioxide concentrations went from 800 to 600 ppm.

Students are provided with a choice of two solutions. Each one is used to test for the presence of a different chemical. How could the students use one of these solutions to gather evidence for the action of photosynthesis?

• Use Fehling's solution on plant leaves that have been exposed to light

• Pump the air from a closed container containing a plant through a sample of lime water

• Use Fehling's solution on plant roots of several different plants after boiling them for several minutes

• Grind up all of the parts of the plant, expose to heat, collect the gas, and use limewater to test it

Which statement is the most likely reason photosynthesis does not occur in the deep aphotic zone?

• Not as much dissolved oxygen from the surface reaches the deepest aphotic zone.

• Not enough soil is present to support plant growth in the deepest aphotic zone.

• Water pressure limits the survival of animals in the deepest aphotic zone.

• Sunlight for photosynthesis does not reach the deepest aphotic zone.
