this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the use of microscope

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

Sapir-Whorf Hypothesis ANT 101 July 19‚ 2013 The Sapir-Whorf Hypothesis theorizes that language is not just voicing something‚ but it is a shaper of ideas which basically means that language can determine our perceptions‚ thoughts‚ and behaviors in reality. Edward Sapir developed and published this hypothesis in the 1920’s. In 1956‚ Benjamin Lee Whorf published his work developing this hypothesis based on his work using the Hopi and English languages. Both of the ideas are commonly known

CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis At the same

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

In addition to phosphate‚ there is caffeine‚ sugar‚ corn syrup‚ vanilla‚ and many other ingredients in colas (Field); all of which could have an effect on a percent transmittance reading from the Spec 20 at a poorly selected wavelength. Using the analytical wavelength minimizes the effect that other factors in the solution have in the reading‚ which in turn minimizes error in the
