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

Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight. When animals digest

A Spectrophotometric Analysis of the Absorption of Green Light Versus Red Light Absorption in Spinach Leaves The goal of the experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a‚ chlorophyll b‚ carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the

Case Study 1: Green Computing Research Project – Part 1 BACKGROUND: Read the Green Computing Research Project‚ Part 1 in Appendix C. Assume the project budget is $500‚000 and will take six months to complete and that you must select the project team as soon as possible. Use project charter examples from Chapters 3 and 4 as support in your answer. Prepare a project charter for the Green Computing Research Project. Write a two to three (2-3) page paper in which you include the following:

Case Project 3-1 First I would begin by incorporating the star topology with an extended topology. I would do this because I can upgrade the network by replacing the problem components such as the 10mbs Ethernet hubs and the existing cables. I would replace the hub with a gigabit switch and add gigabit wireless router for the five computers to connect to the network. I would replace the 10 computer network interface cards with a 10/100/1000 Mbps NIC and replace the old cable with cat6 Ethernet

with a new project called “Green Computing Research Project” that mainly aims to improve the computing technology by guiding the organization through better approaches (Deepak‚ 2005). This project mainly aims to enhance the work functionality by providing many new opportunities in the current market. By getting into this project‚ the organization will look into more software solutions to reduce energy‚ improving the performance and efficiency of data centers and focused towards green technology.

Case Project 10-2 Standard biometrics can use a person’s unique physical characteristics for authentication; these types of devices can use fingerprints or other physical characteristics of a person’s body. There are two types of fingerprint scanners‚ a static fingerprint and a dynamic fingerprint scanner. By doing research I found that I cannot recommend using these because of their cost and their reliability. While researching the cost of standard fingerprint biometric readers I found that

Sun light vs articical light One of the main benefits of artificial light is that you can control how many hours of light per day your plants receive. This way‚ those living in northern or southern latitudes can provide their plants with light for growth and development even when the sun sets early‚ in essence tricking the plants into believing that it is summertime and that they should continue to grow rather than become dormant or‚ in the case of annuals‚ die. In addition‚ your plants will receive
