"The light begins…the light ends" Dulce Maldonado Abstract: In this lab the students did two labs in which they learned the process of photosynthesis‚ which involves the use of light energy to convert carbon dioxide and water into sugar‚ oxygen‚ and other organic compounds. Oxygen is released as a product. This process is often summarized by the following reaction: 6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2 The energy of photosynthesis comes from absorbed photons found in light and involves

determine the relationship of different wavelengths of light and the rate of photosynthesis in spinach leafs. The rate of photosynthesis was measured every five min under light colors of white‚ green‚ red‚ blue and yellow under a light intensity of 2000 lux. The rate of photosynthesis was measured by the spinach disk method in which we replaced the air from the disks with sodium bicarbonate using a vacuum. Under photosynthesis‚ oxygen‚ a product of photosynthesis‚ replaced the bicarbonate solution‚ made

under various filters and the percent orange light transmittance through the solution was measured to determine the rate of photosynthesis. This experiment was set up to discover how different wavelengths of light affect the rate of photosynthesis in a spinach‚ DPIP‚ phosphate solution. I proposed that the spinach‚ DPIP‚ phosphate solution under no filter‚ and therefore exposed to all light will have a highest percent orange light transmittance and a highest rate of photosynthesis. The solution under

Great American Dream. The novel starts and ends with a reference to the green light at the end of the dock‚ indicating an important symbolism. The first time Nick catches sight of Jay Gatsby‚ Gatsby “stretched his arms towards the dark water […] [Nick] distinguished nothing except a single green light […] that might have been at the end of a dock.” (Fitzgerald 2000:25). Fitzgerald ends the novel by again referring to the “green light at the end of Daisy’s dock.” (171). The protagonist of the novel

In the short stories the “Big Brother Little Sister” by Witi Ihamaera and “The Geranium” by Patricia Grace the characters make important decisions that affects their lives. In the course of both stories we learn that the characters suffer from domestic abuse and want to be free but at the end they decide to stay. In Big Brother Little Sister the reader learns that the most important decision that Hema makes is to go back home even thought their life is miserable. When the once the children’s mum

will use a carbon dioxide indicator ( bromothymol blue) to show oxygen is being consumed and carbon dioxide is being released by the beans. Bromothymol blue is an indicator that turns yellow in acidic conditions‚ green in neutral conditions‚ and blue in basic conditions. When carbon dioxide dissolves in water‚ carbonic acid is formed by the reaction: H2O + CO2 → H2CO3 resulting in the formation of this weak acid. If an indicator such as bromothymol blue is present‚ what do you think would happen? (Hint

Photosynthesis is a process through which plants and some certain types of bacteria get energy from the sun’s UV-rays and use it to create and store sugar that is transformed into ATP by cellular respiration later on in the process. In plants‚ this process takes place in chloroplasts‚ which concentrate in the mesophyll cells‚ with the help of chlorophyll‚ the green pigment‚ which is directly involved in photosynthesis. It is important to understand that we see leaves green simply because the green
