Investigation of the rate of photosynthesis of pondweed. Research question: How does the concentration of sodium bicarbonate relate to the amount of oxygen produced by Elodea (Canadian pond weed) in the process of photosynthesis? Hypothesis: If there is an increase in concentration of sodium bicarbonate the amount of oxygen produced will increase because the sodium bicarbonate concentration will increase the carbon dioxide levels. Independent variable- Concentrations of sodium bicarbonate (8%

and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical and biochemical reactions of photosynthesis and cellular respiration

Solar Power In India India’s power sector has a total installed capacity of approximately 1‚46‚753 Megawatt (MW) of which 54% is coal-based‚ 25% hydro‚ 8% is renewables and the balance is the gas and nuclear-based. Power shortages are estimated at about 11% of total energy and 15% of peak capacity requirements and are likely to increase in the coming years. In the next 10 years‚ another 10‚000 MW of capacity and investment of about Rs. 24 lakh crore are required. Fortunately‚ India lies in sunny

Introduction Photosynthesis is a redox reaction which requires carbon dioxide‚ water and light to produce water and a 6-carbon sugar. The process of photosynthesis consists of two parts‚ a light reaction and a light-independent reaction. The method of changing light energy into chemical energy for the formation of NADPH and ATP is done through the light reactions. Light independent reactions use carbon dioxide and the products of light reactions (ATP and NADPH) to form compounds such as glucose

Introduction: Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage‚ where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the

wavelength of light on the rate of photosynthesis was investigated in this experiment. The results from Figure 13 suggest that white light‚ containing all wavelengths of coloured light‚ has the highest rate of photosynthesis. Purple light had the second highest efficiency‚ followed by blue‚ red‚ and yellow light. Green light was significantly less efficient‚ producing the second lowest pH reading (Figure 14). The samples exposed to no light had the lowest rate of photosynthesis. The hypothesis that white

Abstract: Two parts of this lab were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration

Biology 11 December 12 ‚ 2012 Photosynthesis and global warming Introduction: Photosynthesis can reduce the amount of carbon dioxide in the air. It represents a sink for carbon dioxide in the environment. Reducing forests and other vegetation can produce a net increase in atmospheric carbon dioxide. Therefore‚ more photosynthesis might act to reduce global warming. On the other hand‚ this is a more complicated title than it appears at first. Photosynthesis: The process in green plants

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However‚ in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration‚ we need to understand what

Solar eclipse From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Not to be confused with Lunar eclipse. Photo of 1999 total eclipse As seen from the Earth‚ a solar eclipse occurs when the Moon passes between the Sun and Earth‚ and the Moon fully or partially blocks ("occults") the Sun. This can happen only at new moon‚ when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse‚ the disk of the Sun is fully obscured
