Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide‚ affected the rate of photosynthesis. The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). A valid conclusion was made and most of the results were in accordance with the prediction‚ although there were some anomalies present. The errors and limitations were evaluated and some improvements were suggested. Introduction: Photosynthesis

Elodea & Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Introduction This lab has been created in order to find what extent does distance from a light source (5cm‚ 10cm‚ and 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min) in Elodea water plants. Hypothesis:

Abstract Elodea‚ also known as Elodea Canadensis‚ or waterweeds‚ lives favorably underwater. You can find Elodea mainly in natural waters in North America such as ponds‚ rivers‚ or lakes. Elodea has expanded all over the world as well‚ particularly in Europe. This aquatic plant multiplies rapidly and grows in a variety of conditions and environments‚ which is why it’s considered a weed. Elodea is often used in aquariums to stabilize the oxygen balance. It’s a fierce photosynthetic which makes

The elodea plant‚ also called water weeds‚ are plants freshwater plants that grow underwater either loosely rooted or floating around freely. Elodea is native to North and South America and is also widely used as household aquarium vegetation. Elodea rapidly grows through fragments of the plant being dispersed in the water by water currents and human activities. Since no female elodea exists in the United States it has adapted a form of reproduction called fragmentation. Fragmentation is a form

Introduction The photosynthesis lab is designed to quantify photosynthesis‚ enabling a number of variables to be tested for their effects on photosynthetic rate. The production of oxygen‚ is used as an indirect measure of photosynthetic activity.The lab allows the examination of the effects of different wavelengths of light on photosynthetic activity. The other aspect of the lab includes

tubes was tested. The solutions in the opaque tubes were placed on a slide with a drop of blood and observed under a microscope and compared to a control slide with just a drop of blood. Sketches of the observations were made and analyzed. A leaf of Elodea was placed on a slide along with solution X‚ observed‚ and drawn. Solution Y was then drawn through the slide and the previous method was repeated. The same was done with solution Z. The results were gathered and

Storage of CO2 can take place in geological reservoirs (geo-storage)‚ in the ocean or by the mineralization of some other compounds‚ chemical reactants or rocks. In the context of the present Conference‚ we now focus on mineral sequestration (mineral carbonation). Top gas recycling: This removes the CO2 and recycles the carbon monoxide (CO) back into the blast furnace‚ potentially using less than half the emissions of today’s state-of-the-art blast furnaces.

chloroplasts. However‚ the leaves are the major site of photosynthesis for most plants. There are about half a million chloroplasts per square millimeter of leaf surface. The color of a leaf comes from chlorophyll‚ the green pigment in the chloroplasts. Chlorophyll plays an important role in the absorption of light energy during photosynthesis. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. O2 exits and CO2 enters the leaf through microscopic pores called
