1. Look at the molecular formula for plant tissue. Where does the carbon come from? 2. Where does the hydrogen in C6H12O6 come from? 3. When radioactive isotopes of oxygen atoms are put into CO2 molecules and the plant is allowed to photosynthesize, only new plant tissue (C6H12O6) is radioactive and the oxygen gas given off is not radioactive. Draw a dotted line in the photosynthesis equation to show where the oxygen atoms in CO2 go. 4. Draw a dotted line in the equation to show where the oxygen atoms in H20 go.

Schoology lish esc Q A Show What You Know: Photosynthesis (minor summative) Z and S Grades | Schoology 2 BTB is an indicator that helps us to see if carbon dioxide or oxygen are present in a solution by changing colors. BTB is blue when mostly is present, and yellowish-green when mostly is present. This occurs because the indicator can sense the of the solution. In the experiment that you looked at, a plant called Elodea was added to a test tube that originally was 4 color.

To understand photosynthesis, it is important to first understand the larger picture of what molecules the cell uses and generates and how the different molecules cycle between different reactions. The diagram shows a broad overview of the two stages of photosynthesis. Select the label that best corresponds to the lettered blanks in the diagram below. The parentheses represent the choices for each label on the graph. A. (ADP, ATP, O2, Co2) B. (NADPH, Sugars, NADP+, Sunlight) C. (H2O, Sugars, O2, Co2) D. (Sugars, Co2, O2)
