Light Is A Form Of Energy That Travels Through Electromagnetic Waves

Photosynthesis and cell respiration are some of the two most important biological processes that organisms go through. Photosynthesis is the biological process plants undergo to convert light energy into chemical energy. In chloroplasts the chlorophyll act as catalysts for this process. The process uses carbon dioxide (CO2) and Water (H2O) in order to produce glucose (C6H1206) and oxygen (02). Thus, it is read as 6CO2 + 6H2O —> C6H12O6 + 6O2. Photosynthesis is split into two different processes. The first process is light Dependent meaning i uses energy being absorbed to break down and molecules at a rapid photosynthetic rate. The second process is Light Independent meaning it uses ATP and NADH absorbed during when light was present to breakdown glucose instead. Therefore, Healthy plants are green because Chlorophyll absorbs red and blue light, but reflects green light signifying stored light.Some Anaerobic bacteria undergo photosynthesis meaning it can’t grow in oxygen and uses Carbon Dioxide and other substances like hydrogen sulfide to photosynthesis. In general all plants need Carbon Dioxide. (Ensminger, 2014)

The diagram above shows the two stages of photosynthesis. As you can see, light is a key component as it start the light-dependent reactions which produces ATP and NADPH, which is needed in the light-independent reactions to make glucose. So without light, there is no ATP and NADPH produced and thus no glucose produced, therefore the food chain cannot be started. Glucose is also needed to make DNA and hormones for plant growth, it is also require during plant respiration. So it can be established the light is vital for plant growth and it affects the height of plants indefinitely.

The green pigment involved in photosynthesis is chlorophyll. Chlorophyll is green in appearance because it absorbs red and blue light, making these colours unable to be seen. It is the reflection of the green light that reaches out eyes, giving chlorophyll a green colour. This green light that can be seen cannot be used by the plant for photosynthesis. Therefore, theoretically growth should be inhibited in the plants only exposed to green light.

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

Introduction: Photosynthesis can be defined as a solar powered process that removes atmospheric carbon dioxide and transforms it into oxygen and carbohydrates (Harris-Haller 2014). Photosynthesis can be considered to be the most important biochemical process on Earth because it helps plants to grow its roots, leaves, and fruits, and plants serve as autotrophs which are crucial to the food chain on earth. Several factors determine the process of photosynthesis. Light is one these factors and is the main subject of this experiment. The intensity of light is a property of light that is important for photosynthesis to occur. Brighter light causes more light to touch the surface of the plant which increases the rate of photosynthesis (Speer 1997). This is why there is a tendency of higher rates of photosynthesis in climates with a lot of sunlight than areas that primarily do not get as much sunlight. Light wavelength is also a property of

Photosynthesis is the process in which plants consumed inorganic materials like solar light, carbon dioxide and water and converted it to an organic molecule like sugar and an inorganic gas like oxygen. Light is one of the major elements influencing the rate of photosynthesis; direct light concentration affects the noncyclic pathway (light

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms ' activities. Plants need photosynthesis to survive. The balanced chemical equation for photosynthesis is 6 CO2 + 6 H2O ? C6H12O6 + 6 O2. In English terms, this equation translates to six carbon dioxide plus six

In this experiment, I tested the theory of how light would affect the growth of a bean plant. According to gardenguides.com, lack of light is detrimental to plant growth.”Plants that don't get enough light don't have the resources they require, and fail to bloom or fruit.” It is also stated that every plant will need a different strength of sunlight such as full sun, partial sun, or indirect sunlight (also known as full shade). Plants that receive inadequate amounts of sunlight will not thrive.The reasoning behind this is due to a process called Photosynthesis, stated in gardeningknowhow.com. Photosynthesis is a chemical process which converts energy in the form of light into a chemical energy which is a vital food source for plants to thrive.

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

However, the photosynthetic process can be affected by different environmental factors. In the following experiment, we tested the effects that the light intensity, light wavelength and pigment had on photosynthesis. The action spectrum of photosynthesis shows which wavelength of light is the most effective using only one line. The absorption spectrum plots how much light is absorbed at different wavelengths by one or more different pigment types. Organisms have different optimal functional ranges, so it is for our benefit to discover the conditions that this process works best. If the environmental conditions of light intensity, light wavelength and pigment type are changed, then the rate of photosynthesis will increase with average light intensity and under the wavelengths of white light which will correspond to the absorption spectrum of the pigments. The null hypothesis to this would be; if the environmental conditions light intensity, light wavelength and pigment type are changed, then the rate of photosynthesis will decrease with average light intensity and under the white light which will correspond to the absorption spectrum of the pigments.

In this lab, varying wavelengths were used to test how light affects photosynthesis and respiration as a whole. The absorbance of lights from 380 nm to 720 nm of chlorophyll pigment from the Elodea sample

Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special way of using the ATP they produce. Photosynthesis is a process where plants harness the sunlight they receive and they produce carbohydrates, as well as oxygen for living things and other plants. Now the sunlight ultimately powers the process of

Without photosynthesis we would not be able to receive energy. We should be more appreciate of plants, without them we would not survive. This paper will explain the basic components require for photosynthesis, the role of chlorophyll, how energy is transferred, and photosystems I and II and the most precious product results of photosynthesis.

     Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.

In 1779 Jan Igenhousz conducted a very important experiment about photosynthesis. This experiment consisted of a plant with soil in a jar of water that was exposed to sunlight, and then same plant in the jar of water, but in darkness. He thought if i put a plant in water and expose it in sunlight, then it will produce bubbles. First he submerged the plant in a jar full of water. The sunlight from outside was beaming onto the plant.
