What did you eat for breakfast, lunch, and dinner yesterday? Imagine that your body made its own food, internally. Sound crazy? Plants do this all the time.
Plants make their own food in a process called photosynthesis
. In photosynthesis, plants use sunlight, carbon dioxide (CO
2
), and water (H
2
O) to make sugars, which provide them with the energy they need to live as well as the raw materials they need to grow. As a byproduct of photosynthesis, plants produce and release oxygen (O
2
).
A.
Photosynthesis and Light Intensity
1.
In the Gizmo™, observe the aquatic plant. During photosynthesis, the plant produces oxygen, which is visible as bubbles leaving the plant. Set the Light intensity to 0%. (To quickly set a slider to a specific value, type the number in the field to the right of the slider and press Enter.) Check that the Temperature slider is set to 30.0°C and the CO2 level is set to 500ppm. Then select the BAR CHART tab.
What is the rate of oxygen production?
0
What does this tell you about the rate of photosynthesis when no light is present? Explain your answer.
This tells me that since there's no light, there's no photosynthesis being made or occur.
2.
Slowly drag the Light intensity slider up to 40%.
What happens to the rate of oxygen production as the light intensity increases?
The rate of oxygen increases as the light intensity increases
What does this tell you about the rate of photosynthesis as the light intensity increases?
This tells me that the more light that being used, the more oxygen or photosynthesis occurs.
Does increasing light intensity always have the same effect on oxygen production? In other words, experiment with the light slider to see if there are there certain light intensity changes that have no effect at all? Describe what you see.
Well when I turned up the light intensity to over 40 (53%), the amount of oxygen being produced just stayed the same
3.
Select the TABLE tab. You will now use the table to record data on oxygen production at different intensities of light.
4.
Set the Light intensity to 0%. Click on the Record Data button to record this information in the table. Increase the light intensity in increments of ten up to 100% and record data each time.
Does your data agree with your findings in step 2c? Explain why or why not.
Yes my data agrees because I turned the light intensity to 100% and the oxygen stayed the Revised by NVLA: 10/15/2020

same.
5.
To view a graph of your data, select the GRAPH tab. Be sure that Intensity is selected from the options below the graph. Click on the camera icon in the upper right corner to take a snapshot of the graph.
Insert the camera shot of your graph in the space to the right.
Describe the shape of the graph.

B.
Photosynthesis and Carbon Dioxide Level
During photosynthesis, plants use carbon dioxide (CO2) as a source of carbon, which is used to build an energy-rich sugar called glucose. Does the amount of CO2 available influence the rate of photosynthesis? To find out, you will measure the rate of photosynthesis at different CO2 levels.
6.
Click on the BAR CHART tab. The CO2 level indicates the amount of dissolved CO2. Set the Light intensity slider to 90% and the Temperature to 30.0°C. Set the CO2 level slider to 0.0 ppm.
What is the rate of oxygen production when there is no carbon dioxide available? 0
7.
Slowly drag the CO2 level slider to the right up to 200 ppm.
What happens to the rate of oxygen production as the CO2 level increases?
As the CO2 level increases, the oxygen level decreses
What happens when the CO2 level exceeds 300 ppm? When I increased the CO2 level to 300, the oxygen level increased.
8.
Select the GRAPH tab, and select CO2 from the options below the graph. Click Clear Data. Create a graph of oxygen production vs. CO2 concentration.
Record the oxygen production when the CO2 concentration is 100 ppm, 200 ppm, 300 ppm, and so on up to 1000 pm. Be sure to click on Record Data each time so all of the data is recorded in your table.
Click on the camera icon in the upper right corner to take a snapshot of the graph.
Insert the camera shot of your graph in the space to the right.
Oxygen Production vs. CO2 Concentration
Revised by NVLA: 10/15/2020
M3 L1: Gizmo Simulation Lab: Photosynthesis
How is this graph similar to the light intensity graph? It's similar because in the light intensity graph, the line evened out when it reached 40, now in the oxygen flow graph, the line evened out at 400. Basically, both lines reached out when it reached 4, or 40.

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. This transformation occurs because the process of photosynthesis turns

How Do Chloroplasts Capture Energy from the Sun?
Plant cells and some algae contain an organelle called the chloroplast. The chloroplast allows plants to harvest energy from
sunlight, a process known as photosynthesis. Specialized pigments in the chloroplast absorb sunlight and use this energy to
combine carbon dioxide and water to make glucose and oxygen. The complete reaction is:
6CO2 + 6H,0
→ C;H12O6 + 602

Raw Materials (Reactants)
CO, = carbon dioxide
H,O = water

Plant cells can use this process to manufacture glucose, a simple sugar. Some of the glucose is used immediately for cellular
respiration, where it is converted to a high energy compound called ATP. You might recall from studies of the cell, that the
process of creating ATP occurs in the mitochondria. Glucose that is not used right away is packaged as carbohydrates or fats
and then stored in the roots, seeds, and fruits.
All autotrophs can make their own food in this way,…

Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy?
The photosynthetic reaction releases free energy to the surroundings.
The photosynthetic reaction’s free energy is in equilibrium.
The reactants of photosynthesis have less free energy than the products.
The change in free energy (∆G) of the photosynthetic system is less than zero.

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.
