This energy is normally obtained from the sun. When sunlight strikes the plant leaves the chlorophyll pigments within the leaves traps it, chlorophyll is found in chloroplasts which gives the leaves a green colour. Some of the trapped energy is used to break up water molecules into hydrogen and oxygen. The oxygen molecules are then given off into the air and the hydrogen molecules are combined with carbon dioxide to form a sugar called glucose (Great Illustrated Dictionary, 1984). Glucose is the basic food source and it assists with the growth of the plant (Roberts et al, 1993).
This experiment is set up the study the effect of different sodium bicarbonate concentrations on the rate of photosynthesis in spinach (Spinacia oleracea). Photosynthesis is the process by which plants and other photoautotrophs synthesize organic compounds from carbon dioxide (Faculty of Science and Horticulture, 2018). Photosynthesis takes place in the chloroplast of a plant cell, where sunlight, water, and carbon dioxide are used in a reaction to produce oxygen and sugar (Reese 2017). In the photosynthesis reaction carbon dioxide is reduced to make sugar and water is oxidized to make oxygen. In this experiment oxygen production is being used to measure the rate of photosynthesis.
2-Dark Reaction Three ecological varients that have different carbon dioxide incorporation mechanism have evolved during evolution that are C3, C4 and CAM plants. There is no net carbon dioxide assimilation until carbon dioxide during respiration is fully compensated by photosynthetic carbon dioxide fixation. The supply of carbon dioxide to the chloroplast occurs through diffusion process. C3 Plants: In these plants, first carbon dioxide fixation product is phosphoglycerate a three carbon compound. During light reaction, light is captured by (antenna complexes) PS II (P680) after excitation its electrons are ultimately transferred to PSI (P700) through a series of electron carriers.
Title Which frequencies and type of light aided and affected the efficiency of photosynthesis or carbon dioxide consumption in a spinach leaf? Purpose The purpose of the experiment/lab was to observe the effectiveness of different lights during the process of photosynthesis. Background Photosynthesis is a biological process. It occurs in plants, algae and specified bacteria (prokaryotes). Photosynthesis is the process where plants, algae, and bacteria convert light energy into chemical energy.
Biodiversity of co2 assimilation The process of conversion of carbon dioxide into organic compounds by living organisms during photosynthesis is termed as co2 assimilation. Assimilation is also occurring in animals in the form of absorption of nutrients into the body after digestion in the intestine and its transformation in biological tissues. This process is occurring in entire body to help develop new cells. Biodiversity of co2 assimilation in different photosynthetic organisms is described as following. CO2 Assimilation in Photosynthetic Bacteria and Cyanobacteria: Photosynthetic Bacteria possess photosynthetic pigments other than chl.a and can synthesize carbohydrates from carbon dioxide in presence of light like green plants but instead
ADVANTAGES OF USING MICROALGAE FOR BIODIESEL PRODUCTION:- Many articles and reports of research explained various advantages of exploiting microalgae for biodiesel production in equivalence with other uncommitted feedstocks. From a pragmatic point of position, they are gentle to crop, can turn with little or even no care, using water inapplicable for human ingestion and easy to receive alimental. Microalgae procreate themselves using photosynthesis to exchange sun energy into chemical energy, completing total growth cycle every few days. Microalgae can furnish feedstock for various dissimilar types of non conventional fuels such as biodiesel, ethanol, hydrogen, methane, hydrogen, among others. Algae biodiesel comprise no sulfur
The microalgae are usually cultivated in open ponds or photobioreactors systems. The cultivation process requires a suitable amount of carbon dioxide, light, water and other nutrients, which are essential to facilitate the photosynthetic process. Microalgal cultivation produces the biomass containing high-value consumer products and simultaneously captures the greenhouse gas CO2. (Rasmussen
They harness their energy form the sun to carry out photosynthesis (Miller and Levine) However, other things are needed to do photosynthesis as well. Carbon dioxide and water are the key components to process photosynthesis. Chloroplast makes photosynthesis happen. They are organelle, or a specialized structure that performs important task in the plant cell. Cell in the plants co-operate to help
Plants go through a process called photosynthesis. Photosynthesis is the process in which water, carbon dioxide, and light create oxygen and glucose for plants to grow. Water and light go through light dependent reactions. In the light dependent reactions, ADP and NADP+ are converted into ATP and NADPH, which are energy carriers. The product of light dependent reactions is oxygen, which they release some into the air and use some for cellular respiration.
Unlike animals, plants do not require other organisms to obtain food. Instead, they can produce their own nutriment through a process called photosynthesis. Photosynthesis takes place in the chloroplasts (the green pigment of the plant), during which green plants convert light to chemical energy and store the product in the bonds of sugar. For photosynthesis to successfully take place plants H2O, C2O, light and chlorophyll are needed. Photosynthesis doesn’t only provide nutriment to the plant; it also produces oxygen, which is absolutely essential to every living organism on Earth.
