Yeast Mutations due to Ultra-Violet Light Exposure Summary: Mutations have played one of the most important roles throughout life on Earth. Without genetic mutations there would not be the diversity of living species that we see today. Understanding how mutations work and how they are created is an important step in controlling and isolating genes for experimentation. In this experiment we tested the effects of Ultra-Violet light on growing single-celled yeast. We did this by first creating serial

The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the

is to see which color from the light spectrum causes plants to grow faster. The prediction was that read light would cause the most growth in plants and that blue light would result in slower growth. The results did not support the hypothesis. Referring to table‚ one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less. Spinach is a long-day plant therefore it was able to grow better under a constant light source. This would

In this experiment‚ the class examined how the rate of photosynthesis was affected by different light colors at different distances in shoots of a Cabomba plant. The plants were placed in two different beakers‚ one with recently boiled and cooled distilled water and the other with saturated sodium bicarbonate solution. The three different color photoflood lamps used for this experiment were white‚ red‚ and green at four distances of thirty‚ sixty‚ ninety‚ and one hundred-twenty centimeters away

The effect of differing wavelengths of visible light on the photosynthetic activity of Beta vulgaris Introduction Photosynthesis is a crucial biological process that occurs within the chloroplasts of plant cells where CO2 + H2O + Sunlight C6H12O6 + O2. The chloroplasts use light‚ an electromagnetic energy source‚ to produce food for the plant in the form of sugar molecules. During photosynthesis‚ the excited electrons from the light pass through proteins in the electron transport chain (ETC)‚ where

changing light intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined

Do colors keep you warm? Would color affect how warm a jacket is? Many people choose a jacket for aesthetic reasons‚ or just because they like the color that it’s made in‚ but the color of the material itself may affect how warm it actually is. For example‚ a black jacket could stay warmer than a white one‚ because black reflects less light than white or light colors. If the temperatures of the jackets were measured in a controlled environment‚ then the black jacket would most likely be warmer

The Intensity of light is measured in Lux which is the S.I unit of measurement of intensity of illumination of a source. The results are tabulated in the Table 4 and plotted as shown in the Figure 7.
