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

The Effects of Light Intensity on the Rate of Photosynthesis Aim: To investigate the effects of light intensity on photosynthesis. Background: Photosynthesis is a process that plants undergo to produce glucose. The plant then uses the glucose to produce energy which the plant needs to sustain life. The chemical formula for photosynthesis is: Sunlight 6CO2 +6H2O → C6H12O6 + 6O2 Chlorophyll The plant requires light‚ carbon dioxide and

Title and Author 1. The Effect of Extreme Temperatures on the Rate of Photosynthesis 2. Jeffrey Xia 2. Abstract A previous lab in which we conducted‚ tested whether or not the light intensity had an effect on the rate of photosynthesis. We concluded that light intensity did possess an effect on the rate of photosynthesis – the closer the experimental plant units were to the light source‚ the more experimental plant units exhibited the effect of gas exchange in photosynthesis. Therefore‚ in this

The Effects of Snails and Elodea in Water on Carbon Dioxide Levels Problem: How does varying the type of organism (plant or animal) in the level affect the level of carbon dioxide? Background: This lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. Oxygen and carbon dioxide are gases that are vital to all organisms‚ whether it is given or released through that organism. Both plants and animals

investigate the effect of varying the distance (cm) of the Elodea plant from the light source at (5‚ 15‚ 25‚ 35 and 45 (cm)) (±0.05) on the photosynthetic rate by counting the number of oxygen bubbles rising up the test tube per minute (bubbles min^(-1)). The hypothesis was supported because as the light intensity increased‚ the rate at which oxygen bubbles rising to the top of the test tube also increased – for example‚ at the closest distance of 5 cm‚ the rate of photosynthesis was at its highest

Biology lab: measuring the effect of light intensity on plant growth Aim: Investigate the effect of light intensity on plant growth Hypothesis: Light intensity will have an effect on plant growth. With an increase in light intensity there will be plant growth at a faster rate in comparison to when the light intensity is low where plant growth is limited and will take place slowly. When there’s too much light intensity‚ the light intensity will no longer become a limiting factor. A limiting

known as photosynthesis. When photosynthesis is functioning as it should‚ in its fullest capacity‚ all organisms benefit from it in some way. Furthermore‚ scientists aim to better understand the photosynthetic process to help enhance the efficiency and quality of life on Earth. By fully understanding the function of photosynthesis‚ some environmental adjustments can then be made to refine the photosynthetic process. In this lab specifically (Lab No. 7)‚ we isolated specific color wavelengths and recorded
