ABSTRACT Study on the temperature effect on plant photosynthesis is essential for proper understanding of physiology of plants as well as designing of crops that are able to cope-up with temperatures greater as well as lower than optimum growth temperatures. Any fluctuation in temperatures from the optimum temperature affects the overall growth and productivity of plants. Any temperature fluctuation from permissible values have known to affect the PSII, OEC, PQ, PSI, Cytochrome b559 as well as he primary enzyme of...

Photosynthesis and cellular respiration are connected in a way that one cannot take place if the other is not performed. They need each other's existence, basically. It's like they are made to be soulmates; they co-exist. Light + 6CO2 + 6H2O → C6H12O6 + 6O2. Photosynthesis, with the help of light, 6CO2 (6 carbon dioxide molecules), and 6H2O (6 water molecules), produces C6H12O6 (glucose) and 6O2 (6 oxygen molecules). C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP. On the...

Introduction Photosynthesis is very complex process, if analyzed in complete detail. It involves the converting light energy to chemical energy that is used by plants. One of the main aspects of photosynthesis is the flow of electrons. In the process, there is reduction of CO₂, known as carbon dioxide, and the oxidation of H₂0, known as water. This is known as an oxidation-reduction process (Younglove, “Biological Oxidation”). Oxidation is a loss of electrons whereas reduction is a gain in electrons....

Abstract Photosynthesis is the solar energy- dependent process on which food production for human existence ultimately depends. Each day passes with 854 million people hungry and, for that reason, the United Nations Millennium Declaration committed the world’s nations to ‘eradicate extreme poverty and hunger’. Sixty percent of the world’s population lives in Asia, where each hectare of land used for rice production currently provides food for 27 people, but by 2050 that land will have to sup- port at least...

RATIONALE Aquatic plants can be used to demonstrate the oxygen production in the process of photosynthesis because they are specialised to produce oxygen while submerged under water. The common aquatic plant that is used for most of the experiments is Elodea. In theory, when an aquatic plant is placed in a solution in the presence of appropriate light intensity, the plant will photosynthesise and produce bubbles of oxygen gas. These bubbles can be counted and the number of bubbles can...

Introduction With the increasing pressure to feed a growing population, the ability to understand plant growth has never been more crucial, especially as the surrounding environment continues to change due to global warming (Semenov and Halford, 2009)(FAO, IFAD and WFP, 2014). As photosynthesis is directly related to a plant’s potential growth, knowledge of factors that affect this process, such as light and carbon dioxide, is essential. The implications of climate change, with rising concentrations of carbon dioxide and predicted increase...

ABSTRACT The problem that was researched and studied, was how to increase the rate of photosynthesis. This topic is important because photosynthesis is one of the most important processes regarding all life on Earth. By increasing the rate of photosynthesis, the process will be able to generate more energy at a faster pace. The procedure used to study this conflict was placing the same plant (Elodea) into different types of carbonated liquids, to test whether or not increasing the concentration...

Background Most motor oils are made from a denser petroleum hydrocarbon base stock derived from crude oil, with added ingredients to enhance particular properties (Pennzoil, 2019). Oil spillages are a disastrous occurrence in the environment and have a negative effect on both animals and plants. According to the United Sates Environmental Protection Agency, 750 million litres of oil are disposed of improperly every year (Rogers, 2018). Although the impact that oil spills have on animals is spoken about in the...

Flowers are grown all over the world in gardens, greenhouses and in the wilderness naturally, and are shipped across huge distances. While the flower is still attached to the plant the flower benefits from the sugars that the plant's leaves manufacture through the process of photosynthesis (SFGate, Unknown). Photosynthesis is the process used by plants to harness energy from sunlight and turn it into chemical energy. There are two types of photosynthetic processes which are oxygenic photosynthesis and anoxygenic photosynthesis....

Introduction In this study, the effects of Carbon Dioxide (CO2) and light on Eruca sativa growth and photosynthesis have been investigated. E.sativa is a C3 plant, so they undergo carbon assimilation in photosynthesis in a different way to C4 plants (Hall, Jobling and Rogers, 2012; Sharkey et. al, 2007). This is important, as C3 and C4 plants likely respond in different ways to changing concentrations of CO2. CO2 influences the rate of photosynthesis in several ways; the main cause is...

Abstract The effect of light wavelength on the rate of photosynthesis in baby spinach leaves was determined by recording the consumption of carbon dioxide for four minutes. Red, blue, and green light were tested to determine which color increased the rate of photosynthesis the most. Each color has a specific range of wavelengths to describe it, and the closer the wavelength is to the accepted, the more carbon dioxide was consumed. The graphs supported the prediction that as the wavelength...
