Lesson 4 Laboratory: Photosynthesis Introduction: Elodea is a species of aquatic plant often called waterweed. Like other plants‚ Elodea absorbs carbon dioxide and releases oxygen during photosynthesis. In this lab‚ an Elodea specimen is submerged in water under a lamp with a filter that can change the color of the light. We will measure Elodea’s rate of photosynthesis by measuring the amount of oxygen it produces. We will investigate the effects of light color and light intensity on Elodea’s rate

called photosynthesis. This process assists in nourishing plants and keeping them alive. For example‚ trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason‚ in order to survive the chloroplast in plants must capture light energy from the sun and convert it into chemical energy that is stored in sugar and other organic molecules (Photosynthesis‚ 2014‚ p. 185). In plants that contain chlorophyll‚ the photosynthesis process

In the Kingdom Exploration lab‚ five different organisms were observed under a microscope‚ (Yeast‚ Paramecium‚ Elodea‚ Daphnia‚ Euglena). Each of these organisms is apart of one of the six kingdoms‚ (Eubacteria‚ Archaebacteria‚ Fungi‚ Protista‚ Plantae‚ and Animalia) which are apart of three domains‚ (Archaea‚ Bacteria‚ and Eukarya). In this lab‚ however‚ none of the organisms observed were archaea or bacteria. Also‚ all the organisms were eukaryotes‚ not prokaryotes‚ which are organisms without

Variables: Independent variables: temperature of water where the elodea(plant) is going to be placed Dependent variable: the amount of oxygen produced by photosynthesis reaction Control variables: Light concentration entering the beaker Length of the plant Volume of the water to be precise And of the NaHCO3 What is the variable to be controlled. Why does it need to be controlled. How will you

Observing Various Cells Under The Microscope Chapter 6 Lillian Hayner Biology 211 Lab section 14 New Mexico State University Elodea Wet Mount If cytoplasmic screening is occurring‚ you will see the chloroplast circulating around the cell. Cytoplasmic streaming is controlled by microfilaments in the cell’s cytoskeleton. These filaments of actin and myosin move cellular contents in an active process that uses energy released by breaking ATP down in ADP. How might a cell benefit by

bio-cylinder 3 and what has been discussed during the lectures. Some of the possible reasons for the “extinction” in cylinder 1 were the accumulation of ammonia from the fish urine and a lack of oxygen due to the algae growth blocking the photosynthesis of the original elodea. This of course would reduce the amount of oxygen within the cylinder and cause the fish to die from the lack thereof. However‚ upon analysis of the oxygen levels within the first

increased in mass as well. Bags 1 and 2 increased in mass while bag 3 stayed the same. Bag 4 resulted in a decrease in mass. The results I got from this experiment do support what I predicted before the trials. Above you can see a specimen of an Elodea leaf with a drop of aquarium water. I have labeled the cell wall‚ cell membrane‚ cytoplasm‚ and the chloroplast. If you look closely the cell membrane and the cytoplasm are really close to the cell wall. The cell wall is outer layer maintaining the
