Light Intensity Effect On Butterbur Plant

Plants can absorb a number of different length light waves, although not all of them are equal in power or energy which influences a plants growth. Approximately 80% of light that reaches a leaf is absorbed and depending on its wavelength, may excite chlorophyll pigments (reference text book). Plants absorb both red and purple light waves, however because purple wavelengths are shorter, they contain more energy.

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

All plants photosynthesize to produce glucose, which is stored chemical energy as the plants food can be converted into energy through respiration for life processes. The rate of photosynthesis has three main limiting factors – carbon dioxide concentration, light intensity

Plants capture light energy and transform it into chemical energy. This chemical energy is transferred from plants to animals via the food chains.

The purpose of the lab is to see the effect of different light on daphnia magna and how they are attracted in different color. After we calculate the over all in percentage and divided by the tree to see the light which they were most attracted to. We used daphnia magna (see in figure 1) in our experiment.The different types of lights we tested were red, green,white and UV lights,(see in figure 2). It’s good to know how the behaviour of the daphnia respond. The different types of lights are which is Red light is a warning signal; especially a red traffic signal,Green light authority or permission to proceed,white light is light composed of a wide range of electromagnetic frequencies and that appears colorless to the eye and Ultraviolet or

The way that photosynthesis works is by capturing light energy. This energy is captured in chemical bonds, and meaning that plants use radiant energy to fix molecules together. This is how plants provide their own nutrition from carbondioxide, water, and minerals. Also as part of this process, oxygen is released in the atmosphere which

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

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.

The sunlight is an essential element for the growth of any organism. In particular, plants produce their food through the sunlight. In this lab, we are determined to test the consequence on Mung beans (Vigna Radiata) from different phase of the sunlight. To perform this experiment, we compared two Mung bean plants where one of them under the influence of morning sunlight; whereas, the other plant was kept under afternoon sunlight. While performing this experiment, we were managed to keep both plants

Plants are green because when UV rays from light hit the plant, green is reflected off of the plant while the other colors from the UV rays are absorbed. Scientists at NASA propose that plants grow best when exposed to red and blue light but blue seems seems to provide the most growth. This is because red and blue light seems to be the most absorbed. Even white lights contain a lot of blue UV rays and that is why white lights also seem to grow plants very well. The sun contains all of the colors of the rainbow and that is why the natural sunlight tends to grow plants better than artificial light that might only contain the color that is advertised.

A plant is any of the boundless number of living beings within the biological kingdom Plantae, these species are considered of low motility since this species generally generate their own food by sunlight. They incorporate a large group of commonplace life forms including trees, forbs, bushes, grasses, vines, plants, and greeneries. In this task we are experimenting the relationship between light and plant growth by growing plants in three different lights which are red light, blue light and white light. As I stated above that plants generate their own food by sunlight. Sunlight can be broken up by a prism into respective colors of red, blue, orange, yellow, green, indigo, violet and white. All this lights have specific

The hypothesis for the experiment is that garlic grown under blue filtered light will be the tallest, while garlic under green light will be the shortest. The results of the plant under orange light will be between green and blue light. A crucial component to plant growth is sunlight, which energy that allows a plant to go through photosynthesis and produce glucose. Sunlight contains all of the colors of the visible light spectrum, from red to violet, and each color has a different wavelength (Thiele, 2017). When all the waves are seen together, they make white light. Light is essential in a plant's life. Without light, a plant cannot grow, reproduce, or photosynthesize. Chlorophyll traps light energy from the sun and absorbs primarily blue and red light, while reflecting green light (USCB, 2000). Plants utilize the different colors found in the visible light spectrum to control different aspects of their growth.

Photosynthesis is a very complicated process. It is not as simple as plants need a little sunlight, water, and carbon dioxide, and viola oxygen is produced. There are many steps and processes that occur during photosynthesis which make it very complicated. Now the actual word photosynthesis in Greek means photo- “light”, and –synthesis “putting together”. This is the overall basic foundation that photosynthesis stands behind. Photosynthesis can only happen in plants and some algae, due to them having an organelle called chloroplast. Chloroplast has a pigment, which is called chlorophyll. Chlorophyll is a light absorbing pigment, which allows the plant to control solar energy and use it to distribute energy and food for the plant itself. Chloroplasts are usually located in the green tissue in the interior of the leaf called the mesophyll. A usual cell has around thirty to forty chloroplast. In the inner compartment there is a thick fluid called the stroma, with a system of interconnected membranous
