Effects of Wavelength and Light Intensity on Photosynthetic Activity ABSTRACT The photosynthetic process of eukaryotes revolves around chlorophyll‚ the substance that give plants their green color. Plants convert light energy into chemical energy by means of photosynthesis. This experiment tests the reaction rates of a chloroplast suspension against variables of wavelengths and light intensity. Both a control and an experimental cuvette were exposed to a range of 450 to 750nm of light and varying

Light pollution happened slowly at first which was several decades ago it was a process that was hardly noticeable. A light here‚ a light there‚ burning way into the dark nighttime realm‚ helping us see in the darkness when people all their our beds fast asleep. The process still continues today‚ with little thought ever given to what we are stealing away. Our intentions are good but our methods need adjustment‚ and they needs to be done immediately. In fact‚ our methods should have been changed

"The light begins…the light ends" Dulce Maldonado Abstract: In this lab the students did two labs in which they learned the process of photosynthesis‚ which involves the use of light energy to convert carbon dioxide and water into sugar‚ oxygen‚ and other organic compounds. Oxygen is released as a product. This process is often summarized by the following reaction: 6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2 The energy of photosynthesis comes from absorbed photons found in light and involves

Introduction For the past 30 years Scientist have searched desperately for the answer to salt toleration within plants. The damaging effects of salt accumulation in agricultural soils have influenced both ancient and modern day civilizations alike. Worldwide‚ an estimated 24.7 million acres of once agriculturally productive land are being lost annually due to irrigation-induced salinity‚ according to the U.S. Department of Agriculture. Thus‚ crop production is limited by salinity on 40% of

Sundew plant Sundew are a kind of carnivorous plant. The leaves of sundews are covered with "tentacles". sundew is found throughout all parts of the world. Its greatest concentrations are in Australia and South Africa‚ making them the largest group of carnivorous plants. They have a long-ish head that’s parallel to the ground with small sticky red balls. The insect sticks to the balls and the head curls up to eat it. Besides those there are also some ones in which the heads are the shape of

Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs and circuits

(Cacurbita moschata)‚ beet (Beta vulgaris)‚ and pepper (Capsicum annuum) are all dicot plants‚ which mean that they have two seed leaves inside the seed coat. When they are placed in an environment and are watered with solutions of different acidic and alkaline levels‚ the root growth during germination is affected. The purpose of this experiment was to observe what type of substance‚ acidic or basic‚ increases the growth of roots during the germination process of Cacurbita moschata‚ Beta vulgaris‚ and
