To be more scientific using its equation 6CO2 + 6H2O – Sunlight Energy – C6H12O6 + 6H2O‚ carbon dioxide particles travel through a leaf’s cell surface‚ which is where the chloroplast organelle produces “chlorophyll molecules forming a light harvesting complex absorbing that energy‚ exciting electrons” ((n.d.).

associated with blue light (Brins et. al. 2000). One possible explanation for our results is that due to the high-energy nature of blue light‚ some of the blue light shining onto the juniper needles is absorbed by plant pigments other than the chlorophylls and is not transferred to the photosynthetic reactions. Xanthophylls and carotenes are possibly dissipating the high-energy blue light because xanthophylls and carotenes absorb only in the blue spectrum. These energy dissipation mechanisms operate

been the focus of much attention than any other physiological process in flora physiology. Photosynthesis is a complex plant metabolic process‚ similar to respiration and fermentation‚ in which a plant can synthesize organic matter using light and chlorophyll. According to Kirk 1994: Photosynthesis is a complex physic-chemical process that is the central route in the global carbon cycle serving as single prevalent flux of organic carbon in the biosphere. More so‚ it specifically involves the assimilation

energy. (http://www.yourdictionary.com/photosynthesis) Photosynthesis actually takes place in the stomata where carbon dioxide and oxygen enter and leave the plant. Chlorophyll is the green pigment of leaves and plants that’s in charge of absorbing light for photosynthesis. (http://dictionary.reference.com/browse/chlorophyll) All chlorophyll plants require sunlight‚ but in very different amounts‚ which should be considered when coping with sun and shade leaves. Hypothesis It is predicted that the

Spinach Leaves Introduction Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. The purpose of this experiment is to see how different concentrations of carbon dioxide affect the rate of photosynthesis in spinach leaves. I hypothesize that the greater the concentration of CO2 the faster

transformation of amyloplast into chloroplasts in potato (Solawum tuberosum L.) tuber tissue can be induced by light. Excised potato tuber discs illuminated with white light of 3000 lux bepgn to synthesize chlorophyll after a lag period of 1 day‚ and continued to synthesize chlorophyll for 3 weeks. In this paper we present evidence‚ based on ultracentrifugal sedimentation and immunoprecipitation‚ that the lightmediated synthesis of Ribulose-1‚5-bisphosphate carboxylase began 1 day after illumination

We believed the petri dishes with the red‚ blue and clear film would produce the best results of photosynthesis as compared to the petri dish with the green and black film. This is said because chlorophyll absorbs red and blue wavelengths of light and reflects green wavelengths of light. When referring to the light spectrum‚ red and violet are furthest away from green‚ and would be most absorbed by the leaf. White light is all the colors of the

waste product Referring to the above equation‚ it can be seen that light energy plays the role as the source of energy stimulating the process of photosynthesis. The main pigment that absorbs light energy is chlorophyll which is the green pigment found inside chloroplasts. A green leaf cut out into discs of the same size are used in this experiment. This experiment is carried out to discover how different intensity would affect the rate of photosynthesis. Hypothesis

Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate

Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a
