What are the reactants (inputs) in photosynthesis?
Bonus points if you describe the amount of each reactant.
Water (6H2O), Carbon Dioxide (6CO2), and light energy
100
What was the evidence that photosynthesis occurred in the leaf discs?
The leaf discs floated under the light because they produced oxygen. Oxygen is a product of photosynthesis.
100
What is the relationship between photosynthesis and respiration? Be specific.
The inputs/reactants of photosynthesis (carbon dioxide, energy, and water) are the products of cellular respiration. The inputs/reactants of cellular respiration (glucose and oxygen) are the products of photosynthesis.
100
What organelle is responsible for capturing the sun's energy for a plant?
Chloroplasts
200
What are the products of photosynthesis?
Bonus points if you describe the amount of each product.
Glucose (C6H12O6) and Oxygen (6O2)

Why did we add baking soda to our solution in the leaf discs lab?
The baking soda is a source of carbon dioxide for the leaves to do photosynthesis.
200
Why is sunlight essential to the cycling of energy among living things?
The sun provides the plants with energy. The plants feed the herbivores and omnivores. The carnivores and omnivores eat the herbivores and omnivores. The entire food chain is reliant on sunlight.

What process does this show? 
Photosynthesis
300
What are the reactants (inputs) in cellular respiration?
Bonus points if you describe the amount of each reactant.
Glucose (C6H12O6) and Oxygen (6O2)
300
Why did we add soap to our spinach disc solution?
It dissolves the waxy coating on the spinach so the solution can get in easier
300
How do plants and animals depend on each other? Be specific and relate your answer to photosynthesis.
Animals provide plants with carbon dioxide. Plants provide animals with glucose and oxygen.
300
Which of the kingdoms can do photosynthesis? (Hint: it is more than one)
Plants, animals, bacteria, protists, fungi
Bacteria, protists, plants
400
What are the products of cellular respiration?
Bonus points if you describe the amount of each product.
Water (6H2O), Carbon Dioxide (6CO2), and energy
400
How did temperature affect oxygen production in the plants in the Gizmo?
Oxygen production is maximized around 25 C. Oxygen production stops when the temperature is too hot or too cold to do photosynthesis.
400
Which wavelength of light has the highest oxygen flow? 
Blue light around 450 nms.
400
How does an herbicide kill a tree? (Hint: Think back to lesson 1 when we learned someone used a herbicide to kill their neighbor's tree).
An herbicide prevents the tree from absorbing carbon dioxide, which will prevent it from combining with water during photosynthesis and eventually kill it.
500
Write the balanced chemical equation for photosynthesis.
6H2O + 6CO2 + light energy --> C6H12O6 + 6O2
500
If chlorophyll were red instead of green, making plants red in appearance, which color of light would you expect to produce the LOWEST rate of photosynthesis?
If the chlorophyll were red, red light would produce the lowest rate of photosynthesis. Red would be reflected from the leaves, which is why they appeared red, while all other colors are absorbed. Because red light would not be absorbed by chlorophyll, photosynthesis would not work.
500
Which organelle produces energy for the cell during the process of cellular respiration?
The mitochondria
500
Write the balanced chemical equation for cellular respiration.
C6H12O6 + 6O2 --> 6H2O + 6CO2 + energy
