Absorption spectrum of the Spinach Chloroplast By a Different Wavelength and Photosynthesizes Activity in different light filters Instructor: Dr‚ David Danseraveu Student: Hassan Sedaghat‚ A00345910 Due date: 11/13/2012 Material and Method: In the photosynthesis system‚ plants and other photosynthesizing creatures they use light of the sun as energy by absorbing some specific wavelength. A prepared sample of the chloroplast from spinach was used during this experiment

Without color or light‚ art would be nothing; we wouldn’t be able to see or distinguish anything. Light allows us to see the space about something; when it casts a shadow on something we know the size of something. Without color we wouldn’t be able to differentiate between anything. It allows us to see the edges of something which in turn allows us to form the relationships in size and space. Colors can also be used to accomplish a diverse sense of feelings. For example‚ artists can use colors to add

Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If the

muscle cells and analyze for presence of myosin light chain. Utilizing Western Blotting techniques and using specific antibodies helped to detect myosin light chain. The hypothesis was that proliferating myoblasts could be induced to initiate the differentiation process by depriving the cells of the necessary growth factors and that the differentiation is characterized by the expression of muscle-specific proteins. The results showed that that myosin light chain was not present. It was concluded that

Virtual Lab: Optimizing Photosynthesis Maria Diaz March 12‚2012 Pre-Lab Questions 1. Which two variables are controlled in a similar manner? The two variables that can be controlled in a similar manner are CO2 & the light level. 2. How can you get the results to the investigation faster? You can get the results to the investigation faster by adjusting the speed at the bottom of the water weed simulation. 3. How will you be able to determine the rate of photosynthesis

Biology lab: measuring the effect of light intensity on plant growth Aim: Investigate the effect of light intensity on plant growth Hypothesis: Light intensity will have an effect on plant growth. With an increase in light intensity there will be plant growth at a faster rate in comparison to when the light intensity is low where plant growth is limited and will take place slowly. When there’s too much light intensity‚ the light intensity will no longer become a limiting factor. A limiting

In conclusion‚ one can determine how photosynthesis is impacted by light intensity through the experimentation on ivy leaf disks in a bicarbonate solution. The function of the sodium bicarbonate in this experiment was to provide a sufficient amount of carbon dioxide (CO2) for the photosynthesis process to occur. Without CO2 or any of the other necessary reactants‚ glucose nor oxygen cannot be produced. The leaves rise and sink due to photosynthesis occurring in the plant cells. As the carbon from

Spectrophotometric Analysis of the Absorption of Green Light Versus Red Light Absorption in Spinach Leaves The goal of the experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a‚ chlorophyll b‚ carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the data was graphed

Photosynthesis Lab Gizmo website: www.explorelearning.com Class code: EFVNHTVRGY Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce‚ but most of it is released. In the Photosynthesis Lab Gizmo™‚ you
