Name _______________________ Hour ___________ Date ____________Photosynthesis WebquestWelcome 8th graders! Here is a "webquest" for you to explore different labs and activities that relate with photosynthesis. Please visit the following websites, and answer the relating questions.General overview of photosynthesis: Watch this short animation, and then answer the questions. do plants obtain water?Where in the plant does carbon dioxide enter the leaves? How do these openings close?How does water travel throughout the plant itself? Where is it stored in the cell?In what organelle does photosynthesis take place?Energy from the sunlight is ultimately stored in what macromolecule?Photosynthesis VideoWatch the following video and answer the question: Click on the following link to watch the video (there is no sound) What do plants take in through the roots?What are the tubes that carry water to the leaves called?Where does the leaf get carbon dioxide?Where in the leaf is the sunlight captured?What does the plant release into the air as a waste?What does the plant do with the sugar it makes?Photosynthesis Interactive: Click on the following interactive. Click launch interactive. a picture that demonstrates photosynthesisRespiration and how it works: Listen to the following video and then answer the following question. encloses a cell?Where do nutrients enter a cell?What is energy?The process that releases and traps energy for the cell is known as what?What does cellular respiration require?What exits the cell and is produced as waste?What is vital to every living thing?Light spectrum Experiment: Read the instructions on this website. Then choose different plants and colors of light. Write down your findings, and analyze your results! colors of light are mostly absorbed by chlorophyll?What colors are not absorbed well by the chlorophyll?Choose a plant:Make a hypothesis about which colors of light will make it grow worse/ best:How did you test your hypothesis?What are the independent and dependent variables in your experiment?Explain your data. Did it support your hypothesis?What conclusions can you draw from this experiment?Given that white light contains all of the colors in the spectrum, what do you think would happen if the plants just grew under white light?Fill in table with the following information:Filter ColorAverage Height of PlantsRedOrangeGreen BlueVioletBubbles!: When plants undergo photosynthesis, they release oxygen. In underwater plants, you can see this in the form of bubbles. Using this website, count the number of bubbles that are produced from the plant based on how much dissolved carbon dioxide is in the water and how much light is shining on the plant. underwater plant are we using to measure the rate of photosynthesis?Fill out the table below:Distance of Light (cm)#of BubblesRate of Photosynthesis1001201401601802003. How did the rate change based on distance of light?? Why? ................
