In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis

"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

Physical Light and Spiritual Light In this discussion‚ there are two kinds of light that are going to be compared. The two kinds of lights that are going to be compared against each other in this discussion are going to be; physical light and spiritual light. As we all know‚ the sun‚ stars‚ oil lamps will all eventually burn out‚ whereas the light of God is forever‚ so showing that spiritual light‚ God’s light‚ is much better than physical light. In Genesis 1:3 God said let there be light and there

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability

Indoor sports can be good because a person does not have to worry about the weather. It can rain‚ hail or snow and it will not affect a sporting event. It also does not get really hot and stays a constant temperature. The teams do not have to worry about the terrain being torn up from the weather. There are also sports

As the sun rises‚ birds begin to sing the joy of light and as the day ends‚ the birds fly back into the darkness of night. The darkness of our lives is often transformed by the delusion of light. In James Baldwin’s essay‚ "Sonny’s Blues‚"� the title itself sets up an irony that is explored throughout. The name "Sonny‚" when read‚ sounds like "Sunny‚" meaning brightness‚ light and hope. The word "Blues" presents the reader images of night‚ darkness and sadness. The darkness represents the reality
