    I. Objective: How does the rate of photosynthesis affect the plant? II. Background Research: The Elodea plant (scientific names: Egeria densa, Egeria brasiliensis) has dark green leaves that become crowded toward the top. The Elodea plant grows in a variety of pond habitats but prefers to grow at the bottom of cool ponds. Elodea plants can remain green all winter long. . Water is one of the factors that affect photosynthesis. A shortage of water can slow down or even stop photosynthesis. Temperature

    Elodea Elodea is a genus of aquatic plants often called water weeds. Elodea is native to North America and it is also widely used as aquarium vegetation. The introduction of some species of Elodea into waterways in parts of Europe, the Australia, Africa, Asia, and New Zealand has created a significant problem, and it is now considered a noxious weed in these areas. Elodea canadensis, sometimes called American or Canadican waterweed or Anacharis (a former scientific name) is widely known

    Investigating Factors that Affect the Rate of Photosynthesis in Elodea Aim: To find out which factors affect the rate of photosynthesis in Elodea. Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast

    The Effect of Light Intensity on Photosynthesis Of Elodea Canadensis Introduction I wanted to find out how much the light intensity affected the Photosynthesis in Elodea Camadensa. I decided to do this by measuring the amount of oxygen created during photosynthesis. Photosynthesis is the procedure all plants go through to make food. This process uses Carbon dioxide, water and light energy. It produces Oxygen and Glucose. [IMAGE]Carbon dioxide + water Light Energy glucose + oxygen

  • The Effect of Light on the Organic Plant Elodea

    845 Words  | 2 Pages

    The Effect of Light on the Organic Plant Elodea Aim: To calculate the rate of photosynthesis from the number of oxygen bubbles produced by the plant. Photosynthesis: The process by which green plants use the sun's energy to build up carbohydrate reserves. Plants make their own organic food such as starch. Plants need Carbon dioxide, water, light and chlorophyll in order to make food; and starch and oxygen are produced. Carbon dioxide and water are the raw materials of photosynthesis

  • An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea

    Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea Plan: Method: 1) First I will put some water into a boiling tube and add 5 spatulas of Sodium Hydrogen Carbonate. I will add 5 spatulas of Sodium Hydrogen Carbonate as it reacts with water and forms carbon dioxide; also I have so much so that I have carbon dioxide in excess. 2) Then I will cut off 5cm of elodea and place it into the boiling tube. 3) Thirdly I will place the boiling tube in

    see that at what rates photosynthesis happens in this Elodea. We intend to use bulbs, to provide the ‘sunlight’ for our Elodea, if we use any kind of filter, then we would use a blue filter, red filter and yellow. We would not use the green filter, as that would turn the light green. If we turn the light green then the green chlorophyll would reflect the light. We would also have to control the temperature in the beaker full of Elodea, as if the temperature increased too much it would either

  • The Effect of Wavelength on Photosynthesis Rate

    1354 Words  | 3 Pages

    Photosynthesis Rate Aim: To investigate how different wavelength (colors) of light affect the photosynthetic rate. I will use a pant that is a pond weed called elodea. I will measure the rate of photosynthesis by measuring the amount of o2 given off in bubbles per minuet from the elodea. I will do this by placing the Elodea in a test tube with sodium hydrogen carbonate then I will vary the light wavelength (color) using colored filters and count the number of oxygen bubbles given off using

    Although Elodea provides great benefits to the ecosystem such as oxygen, water filtration, and as a food source to various fish and animals, it can also negatively impact us as well. According to the University of Alaska Fairbanks, bodies of water in Alaska are at risk for becoming inhabited by Elodea. It seems that Elodea can “interfere with salmon spawning and deplete lake nutrients” (Frisch). Elodea was first introduced as an aquarium plant to Alaska. The negative effects of Elodea include affecting

  • Elodea Essay

    1106 Words  | 3 Pages

    Elodea are adaptive, oxygenating aquatic plants. They utilize water and light (among others) to photosynthesize in water, and expel oxygen into their environment. However, there are ways the photosynthesis of Elodea can be affected; some ways include a fluctuation in light, temperature, and water level. This lab experiment ran on the theory that different water types could also be a factor to different photosynthetic levels. Elodea were soaked in distilled, tap, and untreated (pond) water and left

    Elodea is an anaerobic plant frequently utilized to understand and manage photosynthesis. Deciding to test the carbon dioxide different levels by setting two beakers containing the Elodea that should weigh roughly weigh between 1.5-2g and one beaker under the light. In the process we put the beakers in the appropriate spots for an hour, drops of phenolphthalein and of 0.02 mL of NaOH were included into every beaker then record the changes in carbon dioxide reproduction. It was presumed that the

    Abstract: In this experiment, the amount of oxygen gases produced by an aquatic plant was measured in various concentrations of sodium bicarbonate. The plant Elodea densa was submerged into two test tubes, containing a specific concentration of sodium bicarbonate for each individual group, and the total amount of O2 produced in mL was recorded for each test tube in a specified in amount of time. The data from the groups was collected a put into table. It was predicated that, with an increase in sodium

    from Elodea plant after being exposed to different temperatures. Elodea also known as Elodea canadensis is a genus of aquatic plants. They are also called waterweeds and is mainly used in aquarium vegetation. It plays a significant role in aquatic vegetation as it produces a significant amount of carbon dioxide under the perfect conditions. Elodea mainly grows in shallow water and can also be sometimes found in deep water. The plant for this experiment is kept in a water tank. We use elodea for this

    In experiment 1, the exchange of substances, through passive transport, was observed. In this experiment, a dialysis membrane was used to simulate a cell membrane, however, the dialysis membrane is not alive. In addition, the dialysis membrane is semipermeable meaning that, depending on size, only certain substances will be able to go through. During the experiment, the membrane was half filled with glucose and, the other half, filled with starch solution. The membrane was placed into a beaker with

    An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. In the results the pattern is that when the light intensity is higher the readings are generally higher. On the graph the less the light intensity the lower the gradient of the curve. the equation for the photosynthesis process is; CO2 + 2H2O + Light Energy ========>
