The Effect Of Light And Total Respiration Of The Plant Elodea Essay

Have you ever really wondered how different variables can affect how plants go through photosynthesis? Well, in this experiment, the purpose was to see how various environmental conditions can affect the overall photosynthetic capacity of a specific plant. The factors, light, darkness, cold, and heat were applied to see how the different components would affect the photosynthesis on spinach plants. Each group was given a different factor to test. Out group was given the light factor. The hypothesis for this experiment is that when adding light as a factor, the light will affect the overall plant photosynthesis.

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

The purpose of this lab is to observe the effect of white, green, and dark light on a photosynthetic plant using a volumeter and followed by the calculation of the net oxygen production using different wavelengths color of white and green light, and also the calculation of oxygen consumption under a dark environment, and finally the calculation of the gross oxygen production.

The purpose of this experiment was to investigate the effects of light intensity on the rate of photosynthesis in a Moneywort plant. By observing the plant in distilled water mixed with sodium bicarbonate, different light bulbs were targeted onto the plant. The measurement of the amount of bubbles present on the plant during the trial of the experiment enabled us to identify the comparisons between the activity of the light and the process of photosynthesis.

The rate of photosynthesis is affected by environmental factors like light intensity, light wavelength, and temperature. This experiment will test the

This lab was conducted to explore the light energy, pigments and the rate of photosynthesis in magnolia leaves. In experiment one a magnolia leaf was used to see the separation of primary and accessory plant pigments using a process called paper chromatography. The importance of this process was to discover which pigment had the highest band along a piece of filter paper and identify various plant pigments in a magnolia leaf such as xanthophyll, chlorophyll a, chlorophyll b, and carotenoids that aid magnolia leaves during photosynthesis. Based on the conducted experiment, it can be concluded that chlorophyll a was the pigment that showed the highest band on the piece filter paper which means that chlorophyll a is the primary pigment in photosynthesis

Also, unlike photosynthesis, cellular respiration is known as a decomposition reaction. During this reaction, the exergonic release of energy is produced by breaking glucose down into smaller ATP molecules, water and carbon dioxide which is released into the air, for use by plants, every time we exhale

The chloroplast contains the pigment chlorophyll which traps light energy (Yablonski, 16). Chloroplasts give leaves their green color by the pigments chlorophyll a, chlorophyll b, carotene and xanthophyll found in chlorophyll; the pigments chlorophyll a and b are separated from the other two pigments through chromatography to determine their absorbance levels (Griffith, 438). These pigments absorb and reflect certain wavelength of the visible spectrum which gives the leaf its green color; it absorbs wavelengths which are red and blue but reflect the yellow and green wavelengths of the spectrum making the leaf appear green in color to the human eye (Glover, et al, 505). Therefore the wavelengths which were reflected make up the colour of the leaves (Glover, et al, 505). This chromatographic separation was conducted to extract the different pigment in the chloroplast extract and to separate each of the different components (Quach, et al, 385). The wavelengths which are absorbed by each chlorophyll pigment are different and are based on the visible spectrum. Chlorophyll a obtains most of its energy from the violet blue, reddish orange and a low amount of the green-yellow-orange wavelengths regions of the visible spectrum compared to chlorophyll b which absorbs all the wavelengths not absorbed by chlorophyll a (Shibghatallah, et al, 3). From the results in the lab, it can be seen that the absorbance values determined fluctuate a lot, which resulted in a graph with more than one peak and downfalls. The highest peak determined by this experiment occurred at 660 nm for both chlorophylls. This can be confirmed by Schmid and his team who determined that the wavelength of chlorophyll a occurs between 660-680 nm whereas chlorophyll b absorbs wavelengths between 645-660 nm (Schmid, et al, 30). Thus, we can conclude by saying the spectroscopy helped us determine accurate

Photosynthesis and Cellular respiration are essential for life on earth. They are connected; Photosynthesis makes glucose and oxygen which are then used in cellular respiration to produce ATP. The wastes of one process are the reactants for the other.  Photosynthesis is the process of converting light energy into chemical energy. It takes place in the chloroplast of a plant. Pigments have the ability to absorb specific wavelengths of light. Different species perform photosynthesis differently, but only light absorbed by the photopigments can be used for photosynthesis. Chlorophyll a is the most abundant photosynthetic pigment in a plant; best absorbs wavelengths of 430 nm which is blue and 662 nm which is red (“Pigments,” n.d.). Elodea Canadensis is a water plant that can perform photosynthesis. Elodea is green, meaning that chlorophyll did not absorb the green portion of the light spectrum. The color green

Introduction: Photosynthesis is the process that converts carbon dioxide into sugars, such as glucose, using energy from the sun and other lights. When light is absorbed by the pigments in the leaf, the energy absorbed is used to incorporate the carbon dioxide into organic molecules in a process called carbon fixation. The equation for photosynthesis in words is carbon dioxide + water (light energy) → Glucose + Oxygen. In numbers it is 6CO2 + 6H2O → C6H12O6 + 6O2. This lab used leaf disks to evaluate the net rate of photosynthesis under various lighting conditions, light, ambient light, and dark. The lab members assessed the leaf responses under sunlight or ambient light. Leaf disks normally float, however when the air spaces are pervaded with carbon dioxide, the overall density of the leaf disk increases and

For lab 12, it is hypothesized that chlorophylls a and b are present in a plant leaf and contribute to the starch production in photosynthesis. Also, products of photosynthesis will be present in leaf tissue exposed to red and blue light wavelengths for several days, but a decreased presence in leaf tissue exposed to green and black light wavelengths. In lab 13, it is expected that since chlorophylls a and b are more polar and smaller molecules than the anthyocyanins and carotenoids, they will travel higher up the chromatography paper than the other pigments.

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.

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.

The overall aim of this report was the conduct an experiment based how different light intensity levels, representing the four seasons in a year: summer, spring, autumn and winter, affects the transpiration rate in a mangrove plant. To do this we had to set the 4 different beakers at different lengths apart, each beaker (from beaker 1 representing summer) placed further and further away from the desk
