An increase in the amount of available glucose
An increase in the amount of available oxygen
An increase in the amount of available light
A decrease in the amount of available carbon monoxide
The reactants of photosynthesis are sunlight, water, and –

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 process by which plants produce sugar using the energy of sunlight
An exchange of gases between animals and the air or water of their habitat
An incomplete diagram of the process of photosynthesis is provided.
(See attached diagram)
What is the missing component that correctly replaces the question mark to complete the diagram?
Soil nutrients
Water
Thermal energy

Students are observing an aquatic plant. They understand that the bubbles they see rising from the cut stem of the plant are the gases produced during photosynthesis. Which of the following observations provides the best evidence that light is the source of energy for photosynthesis?
Plants observed in artificial or in natural light were both seen to produce bubbles.
The frequency of bubbling increases in bright light and slows to a stop in darkness.
The orientation of the light seems to have no effect on the production of bubbles.
The bubbles always rise to the surface of the water, moving towards the light.

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 in the container, carbon dioxide concentration never got above 1,000 ppm.
When carbon dioxide concentration went from 800 to 1,000 ppm the temperature in the container went up.
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 concentration went from 800 to 600 ppm.
