Abstract For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof‚ to demonstrate the necessity of light and chlorophyll in the process of photosynthesis. Background Photosynthesis occurs in organisms which contain chlorophyll. It’s a process that involves the chloroplasts to synthesize glucose

Why is the sky blue? A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset‚ we see red and orange colours because the blue light has been scattered out and away from the line of sight. The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton‚ who used a prism to separate the different colours and so form a spectrum

strong depence on the frequency/wavelength shorter wavelengths are scattered most longer wavelengths travel in (almost) straight lines Rayleigh scattering experiment? 4 RAYLEIGH SCATTERING Why is the sky blue? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere‚ most of the longer wavelengths pass straight through. Little of the red‚ orange and yellow light is affected by the air. However‚ much of the shorter wavelength light is absorbed by the gas molecules

Variagated Leaves Total absence of plastid pigments causes a sector of a leaf or stem to have white patches. This condition is termed variegation (Metrosideros). Variegation is produced when there is a cell mutation (cytological chimera)‚ and all cells produced from that mutant mother cell lack the pigments‚ either because plastids are not present or the plastid cannot complete the manufacture of the pigment apparatus. White‚ therefore‚ is where color is missing. The zones where chloroplasts are

Cohen decided to retrace Tocqueville’s footsteps on roughly the same route to see what of Alexis de Tocqueville did back in 1831. Cohen went through the same course of the Frenchmen from New York to Flint‚ Michigan‚ down the Ohio Valley‚ through the Old south and finally to Washington

Visible Tattoos in the Workplace Stars‚ angels‚ and tribal tattoos are just a few of the most popular types of tattoos around today. Placement of tattoos varies from one person to the next. Placement can range from the arm to the leg‚ even the back is a recent favorite place. Tattoos have become a way for people to express themselves with out saying a word. Tattoos are so popular that one in 10 Americans has a tattoo‚ compared with one in 100 just three decades earlier. At one time tattoos were

the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually made up of many other colours - a fact first

Elodea & Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Introduction This lab has been created in order to find what extent does distance from a light source (5cm‚ 10cm‚ and 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min) in Elodea water plants.
