Photosynthesis Lab Gizmo website: www.explorelearning.com Class code: EFVNHTVRGY Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce‚ but most of it is released. In the Photosynthesis Lab Gizmo™‚ you

Lab #2: Energy in Cell Virtual Lab - Week 3 NAME: ________________________________________ 1. What is the importance of the light and dark reactions in photosynthesis? Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During

human heart rate. To test this‚ we did two full laps of the oval‚ and measured our resting heart rate‚ just before the test‚ just after test and also our recovery rate after the test. Below are the graphs that show the different heart rates of our group of three. We conducted this experiment in a group of three so we could compare results and‚ if the results were different‚ analyse and research why we each had different results. Aim- The purpose of this test was to record how our heart rate would change

Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If the

Everything except the comb was made of ¼ inch Acrylic Plexiglass. The glass helped the group see what was going on in the experiment. The comb was 3D printed to be more accurate. One material was a casting tray which held the Gel in future steps.

Introduction The heart is an extremely important organ in the human body‚ and it must be able to adjust the heart rate for when a person is resting or for when a person is running. Heart rate is defined as the number of heartbeats per unit of time‚ usually per minute (Medicine-Net). The heart rate is based on the number of contractions of the ventricles. The pulse is defined as a bulge of an artery from waves of blood that course through the blood vessels each time the heart beats (Medicine-Net)

environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be
