ADI Lab investigation: Photosynthesis Introduction and goals: In our experiment we worked with photosynthesis‚ which is the process of light energy‚ CO2 and H2O being turned into food for the plant. CO2+H2O+ Light energy=C6H12O+O2 is the formula for photosynthesis. Our group hypothesis was trying to determine weather o2‚ water‚ or the nutrients of the soil determine the mass of the water. The guided question was “Where does the mass that makes up a plant come from?” Methods:

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Photosynthesis summary Photosynthesis [photosynthesis: The chemical change

the resting heart rate and contractile force of the neurogenic heart. The heart rate of the neurogenic and myogenic hearts is regulated by neurotransmitters. Hearts in vertebrates are excited by epinephrine and serotonin although with varied effects and inhibited by acetylcholine. Invertebrates’ heart rates can be increased due to acetylcholine‚ serotonin and epinephrine. Crayfish heart rates will decrease as temperature decreases because they are poikilotherms. The heart rate slows due to decreased

Section 1 Purpose: The purpose of this lab was to separate plant pigments using chromatography‚ calculate Rf values using the collected data‚ and study photosynthesis with isolated chloroplasts. Light energy Light energy Background Information (Activity A): In photosynthesis‚ plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll‚ the primary photosynthetic pigment

INTENSITY OF SUNLIGHT The Intensity of the sunlight is measured at different timings by using Lux Meter which measures the intensity of illumination. The Intensity of light is measured in Lux which is the S.I unit of measurement of intensity of illumination of a source. The results are tabulated in the Table 4 and plotted as shown in the Figure 7. Table 4 Intensity of Sunlight Time Intensity of Sunlight(LUX) 9.15AM 54900 11.15AM 73400 1.15AM 81000 3.15AM 64500 5.15AM 35100 Figure 7 Plot of Intensity

HYPOTHESIS Using train conductors as representatives for all of human kind we can postulate with some accuracy the percent of the population of Earth that are complete and total assholes. If you have ever lived in a small town with train tracks running through it you will know that the conductor of the train is required to sound the whistle at every crossing. This is a 4-part whistle; 2 long‚ 1 short‚ 1 long. My hypothesis is that we can calculate what percentage of the population of planet Earth

Science Lab Report Conclusion Ms. Seaward Jeneé S. White May 16‚ 2015 How Light Refracts Throughout Water My experimental question for my project is: Would light bend at a refractive angle after it propagates through water? The resolution to my experimental question is that light does bend at a refractive angle after it propagates through water. My hypothesis for my project is: I hypothesize that light will bend because of real world examples and experiments. One instance is light refracts

INVESTIGATING FACTORS AFECTING THE RATE OF PHOTOSYNTHESIS! Testing Carbon Dioxide Done by: Krish S. AIM: is to plan and carry out an investigation on factors affecting the rate of photosynthesis. We are doing this by investigating the amount of bubbles produced by waterweed to show the rate of photosynthesis and the effects of carbon dioxide (CO2). HYPOTHESIS: I think that the rate of photosynthesis will increase as the rate of CO2 increases this can be seen by the bubbles produced from

The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the

Testing Reactions to Gravity‚ Light and Food Jacob Kluth and Kelsey Jankowski Introduction This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia
