82. Jack's Info On Hydroponic Plants And Light
    Jack explains about photosynthesis and the lighting needs of plants. For indoor hydroponic gardeners he also has some tips on hydroponic lighting.  
    http://www.hydroponics.com/light/info_light.htm
    
    Extractions: Photosynthesis is the process by which plants use light energy to collect carbon dioxide from the atmosphere and convert it to chemical energy in the form of sugar. The products of photosynthesis serve to nourish the plant and enable it to release free oxygen. Plants use only the spectrum of light that is visible to the human eye. Although the light appears white, it is actually a mixture of all the colours of the rainbow. Pigments, which are the light harvesting units of the plants, absorb certain colours of the spectrum and reflect the rest. Chlorophyll, the main pigment used in photosynthesis, absorbs light in the violet and blue wavelengths as well as in the red, leaving green the colour it reflects, and the plant colour we see. Photosynthesis can also occur indoors, providing the artificial light source used supplies the necessary spectrum and intensity. Wide spectrum fluorescent, metal halide, and high pressure sodium are the types of lights most widely used for indoor growing. All of these lights require a ballast to operate and come in a variety of sizes and wattage's.

The fate of CO in C plants Initially, CO reacts with a 5-carbon compound, ribulose biphosphate An intermediate 6-carbon compound is formed The 6-carbon compound immediately breaks down into two 3-carbon compounds* 3-phosphoglycerate or 3-PGA The above two reactions are catalyzed by RUBISCO * the reason to call this photosynthetic pathway "C " The final product of C photosynthesis 3-PGA is then further utilized in the Calvin cycle The final product Fructose 1, 6-biphosphate Sucrose The fate of CO in C plants C plants have two distinct types of photosynthetic cells, and two distinct types of chloroplasts Mesophyll cells with granal chloroplasts Bundle-sheath cells with non-granal chloroplasts Leaf structure in C and C plants Leaf structure – C plants Leaf structure – C plants Maize leaf C - pathway Initially, CO

84. Why Weren't Plants Created 100% Efficient At Photosynthesis?
    For nature, the creationist reads God. Had God created plants 100% efficient at photosynthesis, He might have been faced with extraneous engineering  
    http://www.rae.org/perfect.html
    
    Extractions: "If God made the world," runs a common argument for evolution, "then why didn't He. . . ?" Most creationists, we expect, can supply the next clause: ". . .give pandas better thumbs? Or improve the design of the human spine? Or make seed production more efficient?" This "God-wouldn't-have-done-it-that-way" argument for evolution appears to many to be among the most compelling in the theory's favor. But rarely do evolutionists give the argument the careful thought it requires. Consider the notion of perfection. If God is perfect, asks the naturalistic evolutionist, then shouldn't His biological productions be perfect as well? Perfection, however, is an exceedingly tricky concept. What, for instance, would be a perfect wristwatch? The naturalist might claim that no intelligent designer would make a watch that loses one second a month, or accumulates dust and rust, or has a case that tarnishes with time, or can be affected by magnets, or cannot withstand a sledgehammer blow. Why stop there, however? With a little imagination, one can also ask why an intelligent designer would make a watch that fails to forecast the weather, or does not have a vibrator alarm in case the wearer is deaf, or does not have tactile hands in case the wearer is blind, or cannot function in a vacuum in case the wearer wants to use it on the moon, or cannot get up and put itself on its owner's wrist . . .and so on.

    Extractions: Photosynthesis Photosynthesis variations Bacteria lack chloroplasts, and instead use structures called chromatophores—membranes formed by numerous foldings of the plasma membrane, the membrane surrounding the fluid, or cytoplasm, that fills the cell. The chromatophores house thylakoids similar to plant thylakoids, which in some bacteria contain chlorophyll. For these bacteria, the process of photosynthesis is similar to that of plants, algae, and seaweed. Many of these chlorophyll-containing bacteria are abundant in oceans, lakes, and rivers, and the oxygen they release dissolves in the water and enables fish and other aquatic organisms to survive. Certain archaebacteria, members of a group of primitive bacteria-like organisms, carry out photosynthesis in a different manner. The mud-dwelling green sulfur and purple sulfur archaebacteria use hydrogen sulfide instead of water in photosynthesis. These archaebacteria release sulfur rather than oxygen, which, along with hydrogen sulfide, imparts the rotten egg smell to mudflats. Halobacteria, archaebacteria found in the salt flats of deserts, rely on the pigment bacteriorhodopsin instead of chlorophyll for photosynthesis. These archaebacteria do not carry out the complete process of photosynthesis; although they produce ATP in a process similar to the light-dependent reaction and use it for energy, they do not produce glucose. Halobacteria are among the most ancient organisms, and may have been the starting point for the evolution of photosynthesis.

86. Timelinescience - Photosynthesis - Resources
    The brief timeline here shows some of the main developments in ideas about photosynthesis which have led to our modern understanding of the way plants make food  
    http://www.timelinescience.org/resource/students/photosyn/photosyn.htm
    
    Extractions: resources Students' resources For many centuries plants were a puzzle. They grew from the soil, and most people, if they thought about it at all, accepted the ideas of the Ancient Greek philosopher Aristotle. He thought that plants were fed by the soil and relied totally on the soil to grow. The brief timeline here shows some of the main developments in ideas about photosynthesis which have led to our modern understanding of the way plants make food. Jean Baptiste van Helmont rejects the idea that plants are fed by the soil. Edmé Mariotte observes that plants are nourished by the atmosphere through the leaves. Charles Bonnet observes gas bubbles given off by a leaf underwater which is brightly lit - an observation still made in school science laboratories today! Joseph Priestley is the first person to show that plants take in carbon dioxide and release oxygen. Jan Ingelhousz discovers that only the green parts of plants release oxygen, and that oxygen is only given off when the plants are lit.

91. Photosynthetic Pigments
    with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs organisms which make their own food using photosynthesis.  
    http://www.ucmp.berkeley.edu/glossary/gloss3/pigments.html
    
    Extractions: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear "colorful". Flowers, corals, and even animal skin contain pigments which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths. Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs organisms which make their own food using photosynthesis . In plants , algae, and cyanobacteria , pigments are the means by which the energy of sunlight is captured for photosynthesis. However, since each pigment reacts with only a narrow range of the spectrum, there is usually a need to produce several kinds of pigments, each of a different color, to capture more of the sun's energy. Chlorophylls are greenish pigments which contain a porphyrin ring . This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll "captures" the energy of sunlight. There are several kinds of chlorophyll, the most important being chlorophyll "a". This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll "a". A second kind of chlorophyll is chlorophyll "b", which occurs only in

    Extractions: Why Do Plants Have Leaves? T he picture at the right shows the International Space Station as it appeared in March of 2001. People live and work only in the thin vertical cylinder. The rest of the station, looking like wings on an old-time airplane, are solar panels. These panels convert sunlight energy into energy usable by the people inside the station. That's the main function of most leaves on most kinds of green plants to convert sunlight energy into something the plant absolutely must have. It's much more than a mere coincidence that the International Space Station is fundamentally similar to a tree stem with leaves spreading in the sunlight. Therefore, a leaf's main job is usually this: To present its broad surface to the sun so that inside the leaf's' green tissue the almost-magical process of photosynthesis can take place. Now, during photosynthesis , sunlight energy is used to power chemical reactions that combine water with the air's carbon dioxide to form starchy carbohydrate. In other words, during photosynthesis, sunlight energy is stored in carbohydrate for later use. Here's the simplified chemical formula for photosynthesis: + C H O O

    Extractions: photosynthesis respiration transpiration balancing act ... plants in communities O ne of the major differences between plants and animals is plants' ability to manufacture their own food. This process is called photosynthesis, which literally means "to put together with light." To produce food, a plant requires energy from the sun, carbon dioxide from the air, and water from the soil. During photosynthesis, it splits carbon dioxide into carbon and oxygen, adds water, and forms carbohydrates (starches and sugars). Oxygen is a by-product. The formula for photosynthesis can be written as follows: Carbon dioxide + Water + Sunlight = Sugar + Oxygen 6 CO + 6 H H After producing carbohydrates, a plant either uses them as energy, stores them, or builds them into complex energy compounds such as oils and proteins. All of these food products are called photosynthates . The plant uses them when light is limited, or transports them to its roots or developing fruits. Photosynthesis occurs only in the mesophyll layers of plant leaves and, in some instances, in mesophyll cells in the stem. Mesophyll cells are sandwiched between the leaf's upper and lower epidermis and contain numerous
