Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate

December 6‚ 2012 Photosynthesis Lab 1. Introduction: Light dependent reactions are the first phase of photosynthesis. It requires light to happen and happens in the thylakoid membrane in a chloroplast. The light energy is absorbed from the sun and converted into chemical energy. Which is then stored temporarily in ATP and NADPH. Hypothesis: I predict that the wavelength intensity will affect the rate of photosynthesis more than light intensity will. 2. Data: # ATP | Light Intensity (Lux)

Running Head: Spatial Navigation in Rats Effects of Lesioned Red Nuclei on Spatial Navigation in Rats Abstract Through cerebellar research we have found that the cerebellum is involved in non-motor functions just as much as it is involved in motor functions. This study looked at the pathway from the cerebellum to the red nucleus to the thalamus into the cerebral cortex. Our hypothesis was that lesioning the red nucleus would show deficits like those seen in lesions of the

In photosynthesis‚ light energy is transformed into chemical energy‚ thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work

Determining the Effect of Light Intensity on Photosynthesis Avalon Pernell‚ et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away

Lab Report: Photosynthesis Name: Purpose of this Lab What is the goal of this lab? What question are you trying to answer‚ or what problem are you trying to explain? In this lab I will perform experiments to explain photosynthesis. I will answer questions like what does photosynthesis do and how does photosynthesis work? Hypothesis After reading the lab instructions (but before starting the lab) record your best educated guess about what will happen in the experiment. Explain

Investigation of the effect of light intensity Equipment: * Data loga * Light sensor * Bulb * Metre ruler X3 Variables: Independent variable – distance of the light sensor from the light source (m) Dependant variable – intensity of light (lux) Control | Why it needs to be controlled? | How will you control it? | Bulb | There are different watts in different bulbs | Use the same bulb‚ but if your one does break half way through the experiment you can use another bulb with the

influenced the Blues. The goal of this paper is to briefly touch on a few of many ways that racism influenced the blues and blues performers. Individuals who made a living from playing the blues often faced racism and discrimination and this caused many of them to move to ‘less racist’ states. Discrimination is seen very blatantly by examining when the blues was first recorded and by examining which artists were recorded. There are countless other ways that racism influenced the blues and these ideas

germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of H2O a day) will grow the best and achieve the greatest height‚ and overall best appearance.
