    Photosynthesis Lab Report Introduction The lights are essential for photosynthesis and it plays a major role. All the food we eat and all the fossil fuel we use is a product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms but usually by plants and algae. All these organisms convert CO2 (carbon dioxide)

    The green leaves Leaves look green because of the chemical chlorophyll. The other reason is that they reflect light in the green spectrum. Chlorophyll absorbs light most strongly in the blue portion of the spectrum‚ and then some in the red portion. Leaves receive their green color during the process of trying to absorb energy from the sun. The sunlight strikes the leaves‚ which contain chlorophyll‚ and the chlorophyll reacts by emitting the green color. Leaves are green because that is the

    Effects of Photosynthesis of Spinach Leaves in Different Light Conditions Introduction Photosynthesis is the process of converting solar energy‚ carbon dioxide (CO2)‚ and water (H2O) into carbohydrates (CH2O) and oxygen (O2). Sometimes the end product of photosynthesis is glucose (C6H12O6). Photosynthesis takes place in the chloroplasts of plant cells. Here membranous thylakoids are stacked in grana surrounded by the stroma. During the light reactions‚ pigments within the thylakoid membranes

    Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around a stem that

    The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the

    Abstract on Determining the Photosynthetic Activity in Plants Using Different Wavelengths of Light using Chromatography and a Spectrophotometer In this experiment‚ the separation of particular pigments‚ contained within a fresh spinach leaf‚ were examined. Paper chromatography is the process of separating certain molecules‚ or pigment molecules‚ based upon their polarity. Four different pigments were examined from the spinach leaf: chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and carotene. Based

    The Geranium Formal letter of complaint I am Sandra a dear friend of Marney’s and I am writing this letter to you because I want to complain about the fact that no family member stepped in to support my friend Marney during her time of need. I recently found out that my friend Marney has been abused by her husband. I have realized that this has been happening after watching a TV programme dealing with the subject of abused wives and what they do to hide their abused lives. I suddenly understand

    Geranium is a genus of 422 species of flowering annual‚ biennial‚ and perennial plants that are commonly known as the cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics‚ but mostly in the eastern part of the Mediterranean region. The long‚ palmately cleft leaves are broadly circular in form. The flowers have five petals and are coloured white‚ pink‚ purple or blue‚ often with distinctive veining. Geraniums will grow in any soil as long as it

    LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place
