However higher intensity have a better effect on the rate of photosynthesis, as it manages to hit not only the top part of the plant but also the bottom leaves, maximizing the effects of photosynthesis to the plants potential. Farmers use the power of grow lights to control the photoperiod during the seasons where sunlight isn’t as strong and photoperiod is lower and to increase the rate of photosynthesis. There are different kinds of grow light and each of them has different function or a different effectiveness: • Incandescent; The incandescent light bulb is used to control photoperiod mostly. This because the majority of energy form released from the light bulbs is heat rather than light, and is therefore an inefficient light source. Also because this light bulb releases mostly heat it must be placed at a correct distance from the plant, otherwise it might cause the plant to burn.
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).
It is based on the fact that vibration and rotation of the atoms inside a molecule has discrete energy levels. Infrared spectrum is a molecular vibrational spectrum. If light passes through the material some of the light will be absorbed that matches the exact frequency. Using a light source, an optical apparatus, an interferometer and detector, we are able to measure the absorbance and transmittance of infra-red light in the substance. Molecular spectroscopy (also called FTIR –(Fourier Transform Infra Red spectroscopy) has advantages in many fields like Medicine to detect Cancer, Pollution control and detection of poisons, and used in chemistry for process control and molecular analysis.
Phytohormones, also called plant hormones are substances produced by plant cells in strategic locations in the plant and these plant hormones are able to regulate predominantly physiological phenomena of plants. Phytohormones are produced in small quantities in plant tissue, unlike animal hormones, they are synthesized in glands. They can action on the fabric itself in which they are generated or at long distances, by transport through the phloem and xylem
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
The fluorescence microscopy is based on the principle that the object can be seen because it emits light. Some molecules become excited on adsorption of radiant energy and later release much of their trapped energy as light. The fluorescence microscope exposes a specimen to ultraviolet, violet, or blue light and forms an image of the object with the resulting fluorescent light. The specimens have been stained with fluorescent dye molecules. Fluorescent dyes are also called fluorophores are molecules that absorb excitation light at a specific wavelength (generally UV) and after a short delay emit light at a longer wavelength.
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
Natural pigments are coloured compounds extracted from living organism (e.g. plant, animal, fungus, etc.). However, the production of natural pigments using microorganisms raised a significant attention due to certain advantages, such as the ability to be grown
