 * Plastic, Plants, and Photosynthesis**

We are doing this experiment to find out if plants could survive in a carbon dioxide free zone. Plants naturally produce food through photosynthesis via sunlight, carbon dioxide, and water in the chloroplasts. **(Photosynthesis,2005).** This is also why plants are green, because the chloroplasts contain chlorophyll which is a green pigment. The process that occurs in chloroplasts-photosynthesis allows the plant to make food by breaking down water for it to combine hydrogen and carbon dioxide to create carbohydrates.(**Light Energy,2012).**After photosynthesis, the carbohydrate is actually glucose which is chained to make other various sugars.To do our experiment we also need to know besides the photosynthesis itself, what plants are made of: plants have rigid cell walls that allow carbon dioxide and oxygen through pours. (**Plants,2012).** So without carbon dioxide then we can assume it will have negative consequences i.e: wilting and decrease of height. Or even discoloration due to lack of carbon dioxide. To test this we will have 6 plants in total (6 Radish Seeds aka Raphanus Savitus, 2 for each of our catagories-- A No Carbon Dioxide zone, a Minimum Carbon Dioxide Zone, and lastly a Maximum Carbon Dioxide zone. TO further test if either plants are able to survive in a(n) no carbon dioxide zone, we will seal one of the openings with 2 types of cork, one that is completly intact and the other with one small opening to test the no carbon and min. carbon zones. Our initial belief is that the plants in the maximum carbon dioxide zone will remain healthier, less withered, and continually grow since carbon dioxide is used as a catalyst to make food for the plant. Independent Variable: Carbon Dioxide Levels Dependent Variable: Plant Growth/Wilting
 * || Average Carbon Dioxide Level || Height of Plant at the Beginning || Height of Plant After ||
 * Plant Number 1-A-No Carbon Dioxide Levels || 0 PPM || 11cm || 4cm ||
 * Plant Number 2-A-Minimum Carbon Dioxide Levels || 970 PPM || 9cm || 8cm ||
 * Plant Number 3-A- Maximum Carbon Dioxide Levels || 2122 PPM || 7cm || 9cm ||
 * Plant Number 1-B-No Carbon Dioxide Levels || 0 PPM || 7cm || 6cm ||
 * Plant Number 2-B-Minimum Carbon Dioxide Levels || 970 PPM || 7cm || 8cm ||
 * Plant Numer 3-B-Maximum Carbon Dioxide Levels || 2122 PPM || 7cm || 8cm ||

Analysis: In our exeperiment, our analysis, proves our hypothesis, heres how. For plant 1-A it was completly sealed off in a no carbon dioxide zone and from our table we can clearly see that infact, it wilts down from 11cm to 4 cm. This is hypothesized because of structurial atrophy, due to a loss of carbon dioxide. Now if we compare it to 1-B the results for both of them are quantitatively the same due to being in the same controlled non-carbon dioxide zone. Though the height reduction this time for 1-B was only 1 cm compared to it's counterpart 1-A- 7 cm loss. Next we can compare the minimum carbon dioxide plants, 2-A and 2-B which suprisingly lost height. We can form a new hypothesis that it was using more carbon dioxide than that was available in the air. Anyhow if we compare it to the no carbon dioxide zones, we see that 2-A, and 2-B have similar results to 1-A and 1-B, due to the main contributing factor of loss of carbon dioxide. Lastly if we compare the minimum and no carbon dioxide zones to our maximum or natural carbon zones, we see a difference. The difference is while 1-A, 1-B, 2-A, and 2-B's growth is limited or stunted the plants in the "free zones" grew. The growth for 3-A was 2 cm, while the growth for 3-B was 1 cm.

Conclusion: Our expirement proves inavariably that plants can not survive without carbon dioxide. You can clearly see from our graph that the plants with minimum and no carbon dioxide eventually deteriotated and lost height. Now that we know plants that dont have exposure to carbon dioxide will wither, will plants without oxygen have similar results? Our new hyphothesis could be, if a plant is denied of ox, then it will wither and die.

Materials: 6 of the same plants (any of the same kind) 1 Plastic Container, 1 Carbon Dioxide Detector, 1 Laptop, 1 Graduated Cylinder, 1 cork with a small opening, and 1 cork intact. Produre: To make this easy to read I will be posting a step-by-step process to recreate this experiment in a controlled enviorment. Steps: 1. Be sure to put on proper lab attire for safety precautions. 2. Plant 6 //Raphanus Savitus// in 6 plastic pots. 3. Be sure to use a measurement instrument to record the plant height for percise results. 4. Next take 2 of the 6 plants and mark them 1-A and 1-B. Then also mark them for No Carbon Dioxide Levels. 5. After that take 2 more of the 6 plants, mark them 2-A and 2-B, and then mark them also for Minimum Carbon Dioxide Levels. 6. After your done, take 2 of the last plants, mark them 3-A and 3-B, and then mark them for Maximum Carbon Dioxide Levels. 7. For each and every plant be sure to record their height with the measuring instrument in cm. 8. Be sure to have logger pro (?) for the next step. 9. Hook up your carbon dioxide detector into your computer's USB port. 10. Start up by selecting either of all the plants but be sure to select 2 of the matching ones, i.e; 1-A and 1-B. 11. Then place them into the plastic container and snugly fit the Carbon Dioxide Detector into the opening and then place the appriote cork into the second opening. 12. Wait 1-2 days for accurate readings, after you do be sure to record the Carbon Dioxide Levels. 13. Repeat for each and every catagory.

Limitations: Human Error: I started to water the plants a couple of days after I watered due to me thinking it was someone else's responsibility, so me and my partner are a couple of days behind. Correction: To fix this, next time I do a(n) plant experiment, i'll be sure to water my plants since it is our responsibilty and hence increase the accuracy of our experiment. Environmental: Some of the Radisch seeds I planted could have been dried out and withered and hence might not grow. Correction: You can't always know all your plants are healthy, so the next time to fix this problem, i'll be sure, if a plant isn't growing on time, to plant a new radish seed. Mechanical: The Carbon Dioxide Detector may have had a glitch or may even have been faulty. Correction: Be sure to test your Detector multiple times for accuarcy.
