Direction: Read and analyze the following laboratory experiment and answer the following question. PART 3: PLASMOLYSIS Materials: safety goggles, red onion, dropper, slides & cover slips, tweezers/ forceps, compound microscope, iodine, small knife, water, salt (5% and 10% solution) Methodology: 1. With goggles on, carefully cut the onion into wedge shaped pieces using a knife. 2. Use an eye dropper to place a drop of water in the center of a microscope slide. Use the tweezers to peel a thin layer of skin tissue from the thick part of the onion wedge and place it in the center of the microscope slide. 3. 4. 5. Add a drop of water and a drop of iodine over the onion tissue on the slide. Carefully lower a cover glass slip at an angle on the stained tissue to allow air bubbles to escape. 6. Examine the prepared slide under the compound microscope at 100X magnification. 7. Record what the cells look like. 8. Prepare a 5% salt solution by adding 5 grams of salt (measure with balance) per 100…

Analysis of the pathological constituents GIVE THE FOLLOWING: - Name of Test/Test Reagent - Positive Result 1) Protein (Note: Presence of protein in urine is termed as proteinuria or albuminuria) A. Heat and Acetic acid test Fill a test about ¾ full of urine. Heat the upper portion gently to boiling for 1 -2 minutes being careful not to shake the tube. Rotate the tube to prevent overheating. A turbidity may be due to albumin, phosphates or carbonates. Add 3 drops of acetic acid drop by drop while boiling between each drop. If turbidity disappears, it is due to carbonates and phosphates. B. Heller’s nitric acid test Place 1 ml of urine sample in a test tube. Hold the test tube in an inclined position and carefully pour 1 drops of conc HNO3 down the side of the test tube. Note formation of white ring at the zone of contact of the two solutions which is an indication of the presence of protein.
Procedure: 1. Prepare 6 test tubes and place 1 ml saliva in each. 2. Add Iml water to tube 1,2 ml to tube 2, 4 ml to tube 3,6 ml to tube 4, 8 ml to tube 5 and 10 ml to tube 6. Mix thoroughly. 3. Transfer 1 ml of each into 6 separate test tubes (discard excess solution) and add 1 ml of 1% starch paste. Mix well and heat in a water bath with temperature maintained at 40°C for 30 minutes. 4. Divide each of the contents of each tube into 2 and test with: a. Iodine Test – to half of the content of each tube, add 1 drop of iodine in KI and note the color produced. Compare the intensity of color in each of the 6 tubes. b. Benedict's – to 1 ml benedict's reagent, add 5 drops of the other half of each tube and heat in a boiling water bath for 3 minutes. Note color of precipitate. 5. Rank each tube according to decreasing reaction rate one (1) being the fastest to hydrolyze and 6 being the slowest.
