Each photo must include a piece of paper with the student’sname and date the photo was taken.Each question is worth 5 points.© eScience Labs, LLC 2014 The table is worth 10 points.Pre-Lab Questions1. Identify at least 3 major similarities and differences between prokaryotic and eukaryotic cells.2. Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic cell?a. prokaryotic cell –b. eukaryotic cell -3. Identify 3 structures which provide support and protection in a eukaryotic cell AND state what their jobis.a. Structure 1b. Structure 2c. Structure 3© eScience Labs, LLC 2014 Experiment 1: Cell Structure and FunctionPost-Lab Questions1. Label each of the arrows in the following slide image:ACDOnion Root Tip: 1000XB2. What is the difference between the rough and smooth endoplasmic reticulum? Discuss structure ANDfunction.a. Rough ER b. Smooth ER -3. Would a plant cell be able to survive without a mitochondria? Why or why not?© eScience Labs, LLC 2014 4. What could you determine about a specimen if you observed a slide image showing the specimenwith a cell wall, but NO nucleus or mitochondria?5. Hypothesize why parts of a plant, such as the roots, are NOT green, but other parts, such as theleaves, are green. Use scientific reasoning to support your hypothesis.© eScience Labs, LLC 2014 Experiment 2: Osmosis – Direction and Concentration GradientsData Tables and Post-Lab AssessmentTable 3: Sucrose Concentration vs. Tubing Permeability%SucroseInitialNetBagPredict:FinalResult:%Sucrose outsideVolumeDisplacementBandWater In,VolumeWater In, Out,in bagbag (in(mL)(mL)ColorOut, Both?(mL)Both?beaker)30%3%YellowBag 1Beaker A Beaker 215%3%RedBag 2Beaker B Beaker 23%3%BlueBag 3Beaker C Beaker 23%30%GreenBag 4Beaker A Beaker 1Take a picture of your results.

If the net displacement for one of the bags was .1 ml, would you consider the solution to behypertonic/hypotonic (depending on the direction of water flow) or isotonic? Please explain why.2. Were your predictions consistent with your results? Please explain why or why not and note anypossible sources of error that may have had an impact on the results. Discuss each bag that had adifference in prediction and result.3. For each of the tubing pieces, identify whether the solution inside was hypotonic, hypertonic, orisotonic in comparison to the beaker solution in which it was placed and note which way water wasflowing – into the bag, out of the bag or both.© eScience Labs, LLC 2014 Hypo/Hyper/IsoIn/Out/Botha. yellow bag 1 –b. red bag 2 –c. blue bag 3 –d. green bag 4 –4. Which tubing bag increased the most in volume? Explain why this happened.© eScience Labs, LLC 2014 5. What do the results of this experiment tell you about the relative tonicity between the contents of thetubing in question 2 and the solution in the beaker?© eScience Labs, LLC 2014 6. What would happen if the tubing with the yellow band (bag 1) was placed in a beaker of distilledwater? Explain why this would happen.7. A. How are excess salts that accumulate in cells transferred to the blood stream so they can beremoved from the body? Research the answer and be sure to explain how this process works interms of tonicity. The name of the process is composed of 2 words: _______ _______B. Explain how this process is different than the one used to transfer water back and forth acrosscell membranes.© eScience Labs, LLC 2014 8. If you wanted water to flow out of a tubing piece filled with a 70% solution, what would the minimumconcentration of the beaker solution need to be? Explain your answer using scientific evidence fromyour experiment.9. How is this experiment similar to the way a cell membrane works in the body? How is it different? Bespecific with your response.a. similar –© eScience Labs, LLC 2014 b.different -© eScience Labs, LLC 2014
