cells. Also to distinguish among plant‚ animal‚ and protest cells and identifying the organelles that are evident in them. Materials and Methods A wet mount with a sample of Elodea (a common pond weed) was prepared. The wet mount is prepared by placing a drop of water on a glass slide. A very small piece of the Elodea is placed in the water and covered with a slip cover. The slide was then placed under the light microscope and observed for cell shape‚ and identifying the different organelles evident

Method In this investigation materials will be needed that include elodea‚ test tube‚ water‚ sodium bicarbornate powder‚ lamp‚ tape‚ razor blade‚ metric ruler‚ metal stand and glass rod. You will have to assemble these equipment to measure the rate of photosynthesis in elodea plant. Procedure; carefully cut the elodea leaf and crush its end then place it in a test tube filled with water. Hold

photosynthesis through the production of oxygen was the clear (control)‚ next was red‚ then blue‚ and finally green. These results are somewhat the expected outcome for the different colors‚ although not exactly. Figure 2. The rate of photosynthesis in elodea plants with different color light filters which include clear‚ red‚ blue‚ and green. The color that produced the highest rate of photosynthesis was clear at .48‚ then red at .28‚ and finally green at

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

Do your best to sketch the cells and structures listed below. Label each feature answer the questions in your lab report. Lab Questions Why are the chloroplasts traveling along the outer perimeter of the Elodea cell? The chloroplasts are traveling along the outer perimeter of the Elodea cell to carry nutrients through the cells and make them into useful substances for the cell to utilize. What is the typical size difference between animal cells and bacterial cells? The typical size difference

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.
