Measuring the Effect of Light Intensity on Photosynthesis Introduction Photosynthesis captures energy from sunlight. Plants‚ algae‚ and some bacteria use the energy captured during photosynthesis for their metabolic reactions. During photosynthesis in plants‚ chlorophyll and enzymes in leaves convert certain wavelengths of light into chemical energy. A simple equation can be used to represent photosynthesis. Enzymes and Chlorophyll light energy CO2 H2O carbohydrate O2 In this investigation

Introduction: Hypothesis: My hypothesis for this experiment‚ the study of the effects of different wavelengths on leaf pigments‚ if chlorophyll a absorbs blue-violet light‚ chlorophyll b absorbs blue light‚ carotene absorbs blue-green light‚ and xanthophyll absorbs blue light‚ then wavelengths of greatest absorption will be 400‚ 450‚ 500‚ and 450 respectively. Independent Variable: Wavelengths Dependent Variable: optimum wavelengths of light for absorption Standard Variable: method of

“Leaf By Niggle” is a story about a journey for oneself and discovering who you are along the way. Niggle’s journey revolves around his painting because he is subconsciously painting his view of heaven. Throughout the story Niggle struggles with showing compassion to his neighbors while finishing his painting before he goes on his trip. In the story after Niggle’s death he then transitions into purgatory before arriving in heaven. The first step of his self-journey is that his painting becomes

network of connected tubes that bring oxygen from the air into our blood‚ nourishing the trillions of cells that make up our bodies. The lungs also clean the blood of carbon dioxide waste created when cells use oxygen (Natural Geographic‚ 2012). In experiment one I hypothesize that the effect of respiration changes on carbon dioxide‚ concentration in exhaled air will be greatest the longer the respiration rate is increased. I predict that during normal breathing the time it takes to detect the carbon

Personalities are reflections of who people truly are at their core. This past week each team member completed a DISC Platinum RuleTM Behavioral Assessment. As stated in the assigned reading‚ this assessment provides its users with the tools for becoming a better person‚ the ability to behave more maturely and productively‚ and to be more successful. Recognition of different personality styles are observed as each team member completes the assessment. All patterns may not work for everyone.

Cellular Respiration vs. Photosynthesis To obtain energy needed for life‚ organisms depend on the processes of cellular respiration and photosynthesis. Though they share the same function of changing energy from one form to another‚ there are many differences between cellular respiration and photosynthesis in regard to the input and output molecules‚ energetics‚ cellular location‚ and ecological importance. The chemical equations of cellular respiration and photosynthesis are opposites. The reactants

Photosynthesis Lab Kozlowski Kendal Schweiss Hour 6 Introduction: Photosynthesis is carbohydrate production using light and chlorophyll. It is a process when green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen‚ using light energy trapped by chlorophyll. The rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. 2H2O + CO2 + light -> carbohydrate (CH2O) + O2 + H2O There is a spongy mesophyll
