Concept introduction:
The hypothetical explanation given by earlier scientists regarding the mechanism of photosynthesis states that oxygen is derived from the carbon dioxide. The remaining carbon atom is added to the water molecule to form glucose. This explanation was challenged by a scientist Van Niel who states that the water splits, and oxygen is released, followed by remaining hydrogen atom combines with carbon dioxide to form glucose.

The law of conservation of matter states that no matter on earth can be created or destroyed. Using the following equation: 6H2O + 6CO2 + Sunlight—> C6H12O6 + 6O2, explain how the process of photosynthesis is an example of this.
The photosynthetic process, used by the chloroplasts of green plants and green algae, is best represented by which of the following balanced equations?
C6H12O6 + 6O2 + 6H2O g 6CO2 + 12H2O
C6H12O6 + C6H12O6 g C12H22O11 + H2O
6CO2 + 12H2O g C6H12O6 + 6O2 + 6H2O
C12H22O11 + H2O g C6H12O6 + C6H12O6
6CO2 + 12H2S g C6H12O6 + 6S2 + 6H2O
In the photosynthesis lab, a group of students found that in the blue light condition, there was a change in absorbance (ΔA620) of 0.324 in extracted spinach chloroplasts. The students later went on a hike and located a plant they had never seen before and were interested in how the photosynthesis rates would compare to their experiment with spinach chloroplasts. They extracted chloroplasts of the unknown green-leaved plant and exposed them to the same experimental conditions as before. The students calculated the ΔA620 to be 0.100.
Which plant (spinach or unknown) has the highest rate of photosynthesis? Explain your answer using evidence, being sure to demonstrate your understanding of the dependent variable.

- Extremophiles are microorganisms that can survive and proliferate in extreme environments. One group of such microorganisms are lithotrophs. These are found deep beneath the Earth's surface, living on rocks under anaerobic conditions and surviving on CO2 as their sole source of carbon.
