Science Net Activities Light and Photosynthesis Pupil's sheet During photosynthesis plants make glucose from carbon dioxide and water. Water contains a little carbon dioxide - it dissolves in water making carbonic acid. During photosynthesis the carbon dioxide is removed. This makes the water less acid and increases its pH. In this investigation you will measure the rate of photosynthesis by measuring the pH. You will try to see how different light levels affect a plant called Elodea. What to do Questions Extra What to do Connect your pH probe and sensor to the interface. Start the software and get it ready to measure: You need to record for up to 30 minutes. See that the software 'knows' a pH probe is connected. If necessary, set your system to read pH7 when the pH electrode is in pH7 buffer solution. Set up your apparatus as shown. Gently clamp the pH electrode in a rosette of a healthy and actively growing part of the plant. Start the computer recording. Arrange the lamp so that it is 30 cm away from the plant. After 10 minutes move the lamp 15 cm closer to the plant. Continue recording.

Fall's colors provide the perfect motivation for teaching about photosynthesis across the grades. Included: We've raked up a pile of activities for you to "leaf" through! It's fall! That means shorter days and cooler nights. And, in many parts of the United States, it means that trees will soon shed their leaves after a final colorful salute to summer. Trees that drop their leaves each fall are called deciduous trees. You might ask your students why they think dentists refer to baby teeth as "deciduous teeth"? See if your students can figure out the connection! And here's another question for your students: Did you know that a tree's leaves are orange and yellow even in summer? Most leaves include the pigments of all three colors. It's just that the pigment chlorophyll (the pigment that makes the leaves green) is a much stronger pigment than the others. It covers the yellow (xanthophyll) and orange (carotene) pigments that are natural to a tree's leaves. But, come fall, a tree's leaves produce less chlorophyll. Now the other colors can show through. And that they do in brilliant explosions of color!

5. Photosynthesis photosynthesis in green plants harnesses the energy of sunlight to convert carbon dioxide, water, and minerals into organic compounds and gaseous oxygen. http://zebu.uoregon.edu/~js/glossary/photosynthesis.html

Photosynthesis Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. Photosynthesis in green plants harnesses the energy of sunlight to convert carbon dioxide, water, and minerals into organic compounds and gaseous oxygen. In addition to the green plants, photosynthetic organisms include certain protists (such as euglenoids and diatoms), cyanophytes (blue-green algae), and various bacteria. The process in photosynthetic protists and cyanophytes resembles that in green plants; it differs in the photosynthetic bacteria in that compounds other than water serve as a reactant and oxygen is not produced. All photosynthetic organismswith the exception of a minor group of bacteria, the halobacteriacontain the light-absorbing pigment chlorophyll, which plays a key role in the transfer of energy from light to chemical compounds. Photosynthesis is the fundamental process that maintains life on Earth. Living cells convert food into energy and structural components. Almost all organisms derive this food, directly or indirectly, from the organic compounds formed within plants during photosynthesis. The stored energy in these compounds is essential for growth, repair, reproduction, movement, and other vital functions. Without photosynthesis, not only would replenishment of the fundamental food supply halt but the Earth would eventually become devoid of oxygen. Just as the organic molecules in the bodies of living organisms contain energy converted by photosynthesis from the energy of the Sun, so do the molecules of fossil fuels. The energy provided by coal, oil, and gas comes from photosynthesis carried on by plants of earlier times and preserved down through the ages, to be released by combustion in modern industrial processes. Most of the energy released both by the burning of fossil fuels and by the metabolism of living cells is given off as heat and must be replaced by the continued input of radiant energy from the Sun.

6. Oxygen: Toxin For Aquatic Plants? Does oxygen really obstruct photosynthesis? by Dr. Gerd Kassebeer http://www.dupla.com/e042.htm

Oxygen: toxin for aquatic plants? Dr. Gerd Kassebeer Are assimilation bubbles poisoning symptoms ? Does oxygen really obstruct photosynthesis? Photosynthesis produces oxygen The most important reaction in nature is the transformation of light energy into chemical energy. Light energy water + carbon dioxide = carbohydrates + oxygen] During this process carbohydrates and oxygen are produced from carbon dioxide, water and light energy. The above formula may be a crude simplification of complex processes, it explains, however, that oxygen constitutes one of the end products and has to be disposed of by the plant in order not to interfere with the photosynthetic process (refer also to the following paragraph). Carbohydrates, for example, are sugar, starch and cellulose. An enzyme with two functions It can be assumed that the metabolic rate of this competing chemical reaction will be no larger than 100% of the first equation's rate because the carbohydrates formed during photosynthesis would otherwise be consumed rapidly instead of re-entering circulation. Oxygen can not enter by diffusion because the partial pressure of O2 in the chloroplasts is considerably higher under light exposure than outside the plant. An equilibrium or balance between main and secondary reaction will develop. This equilibrium is mainly defined by the inflow of carbon dioxide, but also by the outflow of oxygen, whereas the input of oxygen may not play a role at all (see also below).

Experiments to show the factors required in photosynthesis (2) - light and carbon dioxide This unit may be unduly censored by software installed by (well meaning) network managers, resulting in safety advice being removed due to references to uncovered flames - perceived lack of clothing around sources of ignition being apparently seen as a greater moral risk than the physical risk of injury due to burns. These experiments start with destarched pot plants - Geranium ( Pelargonium ) is often used. These are then subjected to various treatments , left in the light for a few days then subjected to decolourising procedures and then finally tested for the presence of starch Destarching the plant: The pot containing the plant is placed in a dark place, e.g. a cupboard for 24 or 48 hours. It is essential that the plant is watered beforehand, and not forgotten about! This is so as to force the plant to use its reserve of starch, and not allow its replacement by photosynthesis. Before proceeding to the next stage, a leaf is removed and checked for the presence of starch (See under the section "Testing a leaf for starch"). If no starch is present, then it is possible to proceed to the next stage. If it is, then it must be returned to the dark.

19. Blue Planet Biomes - Plants Through photosynthesis, plants take energy from the sun, carbon dioxide from the air, and water and minerals from the soil. They http://www.blueplanetbiomes.org/plants.htm

The Importance of Plants Close to 2.5 billion years ago, the earth's surface and atmosphere were stable enough to support primitive life. Single-cell organisms began to develop in the seas that covered the planet. A simple organism known as blue-green algae appeared and spread across the seas. Blue-green algae used sunlight and water to make food, and in the process, created oxygen. As the blue-green algae grew in the earth's seas, they began to fill the atmosphere with oxygen. The oxygen that blue-green algae produced made it possible for other types of organisms to develop. Plants play the most important part in the cycle of nature. Without plants, there could be no life on Earth. They are the primary producers that sustain all other life forms. This is so because plants are the only organisms that can make their own food. Animals, incapable of making their own food, depend directly or indirectly on plants for their supply of food. All animals and the foods they eat can be traced back to plants. The oxygen we breathe comes from plants. Through photosynthesis, plants take energy from the sun, carbon dioxide from the air, and water and minerals from the soil. They then give off water and oxygen. Animals and other non-producers take part in this cycle through respiration. Respiration is the process where oxygen is used by organisms to release energy from food, and carbon dioxide is given off. The cycles of photosynthesis and respiration help maintain the earth's natural balance of oxygen, carbon dioxide, and water.
