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
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
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
types of plants, whether on land or in the water. Photosynthesis is a process that plants use every minute in order to survive. They create the food that they need from Carbon Dioxide and Water. Here is the full, balanced chemical equation; [IMAGE]Carbon Dioxide + Water Oxygen + Glucose CHLOROPHYLL Or the chemical equation: [IMAGE]6CO2 + 6H2O 6O2 + C6H12O6 With these equations, we are going to see that at what rates photosynthesis happens in this Elodea.
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
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
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
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
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
Willow Tree Experiment, Joseph Priestleys Mint in Jar Experiment, and Jan Ingenhousz Elodea & Bubbles Experiment. In all three of these experiments they talk about things dealing with plants. Jan Baptist van Helmont talks about the weight of plants. Joseph Priestley talks about how even in a closed container a fire can burn if a plant is inside of jar to produce oxygen. In Jan Ingenhousz experiment he talks about plants producing oxygen under water. Even though all three experiments are completely different
there is slightly higher absorption in the blue region by the plant. The red has the largest wavelength in the visible spectrum which produces the least energy. The reason why green is at the bottom of the list of absorption in a plant is because
Effects of varying wavelengths and Light Intensities on the Rate of Photosynthesis in Elodea spp. And Polarity of Spinach on Chromatography Paper Geneva Gama Hawaii Pacific University Photosynthesis is one of the most essential processes on earth for biological life. It is the process by which green, as well as other specific types of organisms, transfer light energy into chemical energy. It involves enzymes, and electron transport chains –which make it quite a complex process (Light Wavelength
the chloroplasts of green plant cells; it can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive. The reason light intensity is being used compared to whether or not a plant needs light. Is because
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
Geography is the study of Earth and its physical features. It is the study This includes its landscapes, peoples, places, and environments. In the study of geography, there are five themes; location, place, human-environment interaction, movement, and region. Location refers to the particular place or position. There are two types of location: absolute location and relative location. Absolute location is often identified as a grid coordinate on the surface of the Earth. Also, finding absolute location
by animals. Herrera and Pellmyr (2002) explain, "The lack of mobility in plants creates a physical obstacle in the dispersal of their genes. In a majority of all plants, this obstacle has been alleviated through the formation of mutualisms with animals that transport pollen grains between stigmas" (p. 157). So in empty forests, where fauna is compromised by defaunation, pollination of large plants is obstructed. However, in the ideal forest, without human interference
doing back breaking work on their garden, but not anymore, with Aquaponics the need for any tilling, digging, or weeding is eliminated. Aquaponics combines Aquaculture (Raising fish in tanks), and Hydroponics (Growing plants without soil). The outcome is a working system that provides plants with all the nutrients they need, while using a minimum of space, effort, water, fertilizers, and pesticides. Aquaponics allows farmers to use up to 90% less water than normal farming would use, so instead of watering
representing new species (Hebert et al., 2005). Barcoding promotes biological applications such as identification of medicinal plants and even plant nearing extinction (Muellner et al. 2011). DNA Barcoding defines the expansion and discovery of the world’s ever-expanding inventory of species’ diversity. DNA barcoding requires it to be standard, scalable and minimal. Plants’ low rate of nucleotide substitution in the mitochondrial gene has been the source of major debate regarding a plant’s code for
photosynthesis to take place in green plants. I choose this topic because I wanted to see if light necessary for photosynthesis is really. It is also a very interesting topic because most living things need light to function, survive and grow. Photosynthesis is the physic-chemical process by which green plants use light energy to photosynthesis. When Photosynthesis occurs it takes in the co2 from the atmosphere and releases oxygen as a bi product. In addition the plants provide energy for humans. For a
