needs to. Elodea nuttallii is a native aquatic plant from North America. It is very similar to the plant Elodea Canadensis. Elodea nuttallii has short leaves around 6-13 mm in length and 1.5 mm in width. It is generally paler than Elodea Canadensis and more branched stalks. Its leaves are folded along the midrib and bent like claws. Elodea nuttallii was first identified as Hydrilla verticillata, this species was first discovered in Great Britain 1914. Then, it was correctly identified as Elodea nuttallii
The Elodea was already located in a container of water. First, add 150 mL of dilute H2O to a beaker. Use a straw to add carbon dioxide to the dilute H20 by breathing bubbles approximately for one minute. Blowing the bubbles will make sure that each beaker is even with the same amount of CO2. Using 3 different beakers, separate the 150 mL with dilute H20 into 50 mL per beaker. Label each beaker: Elodea Black Light, Elodea Light, No Elodea. Grab the 2 pieces of Elodea from the container using forceps
by: Nayobe Bivins Stephanie Wigmore Abstract The objective of this experiment was to determine the relationship between light and the rate of the photosynthesis of the Elodea plant; that is, to describe the effects of a light source on photosynthesis. To test the effects of light on photosynthesis in this experiment, the Elodea plant was placed under the presence and absence of a light source. Furthermore, the balanced chemical equation of photosynthesis 6CO2 + 6H2OC6H12O6 + 6O2 depicts that carbon
Mesocosm Design Lab (Practical #5) Anshul Krishnan : 11M Task: Design, set up, monitor and evaluate a sealed mesocosm, with a view to achieving a sustainable model. ———————————————————————————————————————— Defining The Problem: A Mesocosm is a designed natural environment which can be manipulated and can be controlled. The Main purpose of building a mesocosm is to be able to observe nature’s balance without human intervention; something that has been destroying our planet’s environment since
We hypothesized that the elodea planted mounted in distilled water would be turgid when placed in the hypotonic solution. The results showed the elodea plant mounted in 0.9% saline solution was similar to that of the 0.50 mL of distilled water and 0.9% NaCl with the blood cells. When mounted on the 0.9% saline, the cell shrunk slightly due to the isotonic solution. And finally, when the elodea plant was mounted on 5% saline, the cell drastically shrunk due to
Photosynthesis Assignment Lance Misland Ms T Joshua Marine Biology 1 (MAB150S) 14 September 2015 Introduction: Photosynthesis is the process that primary producers undergo in order to make food for them; they do this by converting light energy into chemical energy, storing it in bonds of sugar. This process occurs in organisms that have chloroplast (plants and some algae), using chlorophyll to capture the light. However, plants only need light energy, CO2 and H2O to make sugar (Biology, 2014)
In this essay i will be going over the three experiments, jan baptist van helmont willow tree , joseph priestley mint in jar , and lastly jan ingenhousz elodea and bubbles. they all show the findings of photosynthesis. Photosynthesis is the function in the plants on which they make food with. The plant also get energy from this process and they make oxygen for us to breath. The basic formula for photosynthesis is carbon dioxide, water then light to make sugar and oxygen. All plants
Background: In this lab experiment, students were able to work with the concept concerning the osmosis ideology. This was observed through two different processes where plant and animal cells were utilized. In using these cells, the students were able to identify and experience how Osmosis works with osmotic concentration, osmotic potential, water potential, and osmotic pressure. All of these concepts and the properties of the cells let us make observations that would help piece the entirety of
through the microscope. The microscope showed the Cell Membrane, Nucleus, and the Cytoplasm. In figure 3 the slide was human blood Cells. The only two structures visible in the human RBC was the cell membrane and the cytoplasm. During figure 4 an elodea leaf was placed on a slide to be looked at under the microscope. Because the leaf is a plant cell membrane, chloroplast, and the cell wall were al seen under the microscope. In figure 5 onion skin cells were under examination. Under the microscope
Method and Equipment Ecosystem jar contents A 2 litre plastic jar with 589g of sand was used. It was filled with the following: 1439ml of creek water, 1.73g Elodea, 6.13g Vallisnera and 3.30g of Lemna. The jar was covered with netting. Probe testing Using an electric probe, accurate levels for pH, O2 availability and water conductivity can be measured. Chemical testing Two 5ml samples of ecosystem water was extracted into two test tubes, where chemical indicators for phosphorus and nitrogen were
