Light, The Primary Source Of Energy In Photosynthesis

746 words - 3 pages

Light has a wave nature and particle nature. The smallest parts or units of light are called photons and the amount of photons absorbed per unit time determines the brightness of light. Wavelengths are a certain amount of energy each photon possesses as they vibrate. Chlorophyll reflects the wavelengths green part of the light spectrum because it is green and the plants that contain chlorophyll are green as well.
This article may not be reliable because there was no date or author noted. This article clearly examines in what form light is absorbed and the process thereof.
Article 2:

They did not need to develop more effective ways of absorbing light as there was plenty available.
This article my not be very reliable as there was no date present on the website so we do not know when last this article was updated and whether it is flawed in the information given. This article clearly states that photosynthesis would not occur if it weren’t for the absorption of light and no products such as glucose and starch would be formed either. It also tells us that the green plants that contain chlorophyll are designed for light absorption clearly emphasizing that light is a very important factor.
Article 4:
Light is the primary source of energy in photosynthesis is therefore called a “light reaction”. Light initiates the function of the chlorophyll and allows for the splitting of the water molecules and produces oxygen as a bi-product.
This article is reliable to an extent as no date has been stated on the webpage about when this article was last updated showing that there might be errors. The above article also explains that photosynthesis is known as a light reaction showing again that light is a crucial factor in this process.
Article 5:
Oxygen is given off after the splitting of the water molecules which...

Determining the Effect of Light Intensity on Photosynthesis

2519 words - 10 pages Determining the Effect of Light Intensity on Photosynthesis Aim In this experiment, I intend to alter the light intensity and measure its effect on photosynthesis through the production of oxygen Introduction Photosynthesis is the process by which green plants provide a source of energy for respiration. The formula is as follows- Carbon dioxide + water Carbon dioxide and water are chemically combined

How light intensity effects the rate of photosynthesis

1890 words - 8 pages effect photosynthesis, they are as follows:Background light - The amount of light in the room, I won't be able to do a perfect experiment each time but can get the light in the room around the same level each time we do the experiment this can be done by making sure the whole room is dark and the only light source is the lamp we are using for the test.Heat from other sources - Heat from sunlight which comes through the window into our classroom also

How does light intensity affect the rate of photosynthesis?

2729 words - 11 pages further away, the light intensity increased, therefore the rate of photosynthesis increased. The pondweed had more light energy for photosynthesis and was therefore able to produce more oxygen bubbles in one minute.Looking at the light intensity graph, you can see a trend. It shows that the rate of photosynthesis and light intensity are proportional to each other. This is because there is a straight line of best fit going down as the distance

The New Source of Renewable Energy

2239 words - 9 pages research is needed to improve the output energy and become more efficient with less cost in production. The new technology is to increase the percent of usage of bioenergy as primary source of energy in the world. The new result from research is using algae to produce biofuels. Algae are very useful because it use carbon dioxide and produce oxygen. It is like tree. So it can reduce the carbon dioxide in the air. Then algae can be extract oil. It can

The Jungle a Primary Source

1053 words - 5 pages The Jungle written by Upton Sinclair shows a vivid description of life and the living condition in the meat and other industry around Chicago. The Jungle is full of examples of historical content about profit, corruption, and condition making it a good primary source. To determine whether a book is a primary source or a secondary source, a person needs to know what a primary and secondary source is. First, a primary source, define by Princeton

The Use of Coal as an Energy Source in the United States

1361 words - 5 pages in electricity generating power plants. Figure 1: http://www.teachcoal.org/aboutcoal/articles/coalreserves.html There are many advantages to using coal because it is an abundant source of energy, provides many jobs in the coal plants, and is dependable. But there are also many detrimental factors as well, since the production of coal results in air pollution, sulfur dioxide emission, carbon dioxide emission, acid rain, and hazardous waste [4

The Use of Hydrogen as an Energy Source in the Future

1662 words - 7 pages The Use of Hydrogen as an Energy Source in the Future There have been many stories in the newspapers, on TV and on the radio about the state that our planet is in, and most of the time they are not too positive. We hear about pollution, and global warming most frequently, which are both caused mainly by the burning of fossil fuels. Because of this, organizations and governments have started to invest money in researching alternate forms of

Searching for the Energy Source of the Future.

3241 words - 13 pages energy is produced by nonrenewable resources, this is a far cry from where we should be (Haley 3). Until the late nineteenth century the majority of America’s energy came from burning wood. Wood burning was used for things like heating homes and cooking food. Water wheels were another source of energy drawing energy from running water as they spun. In

why is the jungle a primary source?

993 words - 4 pages everyone to understand what happened in the past, Upton Sinclair used The Jungle as a primary source. There was specific evidence with several witnesses in The Jungle. Jurgis was a character in the novel and became a key eye witness during several events that were later documented. These key situations enabled certain regulations to be implemented. Working conditions were severely tormenting to the laborers. The Jungle was an element that brought these situations of the working industry out in to the light. However, the reality of the novel was meant for people to see the house of horrors i.e. meatpacking industry.

Cantu (292) and Fresch (94) have found that preservice teachers often do not have a clear understanding of the definition of primary sources. Before we can teach with primary sources we must understand exactly what they are. The Library of Congress defines primary sources as “original items or records that have survived from the past, such as

The Effect Of Light Intensity On The Rate Of Photosynthesis

836 words - 3 pages create sugar. Prediction: I predict that if there is a higher amount of light intensity on the plant the rate of photosynthesis is going to increase due to there being more energy available to be used to create sugar. As the light gets further away from the plant a weaker source of energy will be reaching the plant and therefore there will be a decrease in the amount of photosynthesis occurring. Safety: Test should
