This experiment tested whether or not baking soda affected the rate of photosynthesis over time. For this experiment there was a beaker containing 100ML of running distilled water added to a beaker with 1% or 1 gram of baking soda. Then another beaker was placed beside that beaker with 100ML of 0.2% sodium bicarbonate. This was done to test the rate of photosynthesis with different amounts of baking soda over time. Both beakers were placed under a red light with 25 watts of electricity for two trials at 23 degrees Celsius. After 10 minutes in the first trial, it showed 1% of baking soda caused a greater amount of leaves to float over time; while the 0.2% sodium bicarbonate caused a fewer amount of leaves to float to the top of the beaker overtime.
Carbon dioxide is necessary for plants to carry out the process of photosynthesis, which is an important process because it allows plants to produce glucose, as well as oxygen. Based on evidence from previous experiments, the growth of the plant will reflect the amount of CO2 gas that is present in the environment (O’Leary and Knecht 1986). This means that the plant growth relies on the carbon dioxide in the atmosphere in order to be successful. Therefore, in several cases, it has been noted that when the concentration of CO2 is doubled, the plant growth will similarly increase (Carter et al. 1997). So, it can be concluded that by raising the amount of carbon dioxide in an environment, the surrounding plants will experience an increase in growth.
As the light is increased so would the rate of photosynthesis. Apparatus: boiling tube, 250ml beaker, bench lamp, ruler, sodium
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 = =
The Effect of Wavelength on Photosynthesis Rate Aim: To be able to To investigate how different wavelengths (colors) of light affect the photosynthetic rate of the synthetic. 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 minute 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.
To make sure that my test is fair I will make sure to keep all the
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.
The primary nutrients that plants require are carbon, hydrogen, and oxygen from air and water. Sugar has a different effect on animals, humans, and plants. In this experiment, we are testing the effects of sugar on the growth of wheatgrass. For this experiment, we used regular sugar that we put in our food and drinks. To test our hypothesis we are using two groups control and experiment group. The control plant received only water but the experimental plant received sugar but, both plants were placed in the same temperature and same amount of water. Our hypothesis was correct, experiment plant “sugar water” yield more plant growth than control plant “water”. This experiment shows the sugar water plant grow faster than water because of the average of both plants. The sugar water experiment plant had longer in length compared to water control plant.
Carbon dioxide or CO2 is known to be one of a number of gases that are astonishingly transparent to the visible light that falls on the Earth from the Sun, but it absorb the infra-red radiation that emitted by the warm surface of our Earth, to prevents its loss into space. Moreover, CO2 has varied considerably and this affected the Earth’s temperature. Most common source of this CO2 is known as the fossil fuel. Fossil fuels are primarily coal, hydrocarbons, natural gas, or fuel oil that formed from the remains of the dead plants and also animals. The burning fossil fuel that has been created by humans is the largest source of emissions of the carbon dioxide.
The Effect of Light Intensity and Temperature on the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. To do this, I will place a piece of pondweed in varying light intensities and temperatures, and observe the amount of oxygen being given off. I am using pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water. Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined as the production of simple sugars from carbon dioxide and water causing the release of sugar and oxygen.
This project is about testing to see what affects different types and concentrations of greywater, water from showers, washing machines and other water with traces of soap, on the growth of plants. Climate change is a major problem that applies to the whole world and needs to be addressed before it gets worse. As a result of climate change, natural supplies such as fresh water, are declining which is resulting in less water able to be used in ways most necessary to people, such as drinking and growing crops. In this experiment, sixteen pots were each filled with one snow pea seedling and watered with a different dilution ranging from only water to three different concentrations of two types of laundry detergent, Radiant and Earth’s Choice.
Investigating the Effect of Light Intensity on Photosynthesis in a Pondweed Aim: To investigate how the rate of photosynthesis changes at different light intensities, with a pondweed. Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis. The plant may stop photosynthesising when the pondweed is at the furthest distance from the lamp (8cm). Without light, the plant will stop the photosynthesising process, because, light is a limited factor. However once a particular light intensity is reached the rate of photosynthesis stays constant, even if the light intensity is the greatest.
leave is thin, so it is easy carbon dioxide to diffuse in to each of
Yes the hypothesis was supposed, which was "Germinating seed would take in more oxygen because they are actively going through cellular respond growing. This is shown in the data when looking at the Corrected Difference at 5 minutes germinating peas was at .05 and dry peas with beads was only .01, then looking at the data at the end at 20 minutes germinating peas were at .24 and dry peas and beads were at .04. The germinating were ahead of the dry peas with taking in more oxygen. The independent variable was the germination of the peas. The dependent variable was the amount of oxygen consumption. Germinating peas are growing and going through cellular respiration at a higher rate, this effects oxygen consumption because because the higher the
The Importance of Photosynthesis and What it Does for Life According to scientists, life is “the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death, also the way of life of a human being or animal. ”("Life,”) In order for one to have life, one must have the nine characteristics to be considered a living thing. These nine characteristics are: all living things are made up of cells, living things are able to reproduce, living things use energy, maintain homeostasis, respond and adapt to the environment, grow and develop, have a life span, evolve over time, and are interdependent. All of the nine characteristics have one thing in common, something that is needed for all living things to work, even if they do not know it.
An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in 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 ] 6CO 2 + 6H20 C 6 H12 O 6 + 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 nor survive.
