LAB REPORT GRADING GUIDE

CELL BIO II Experiment #4:

  • Introduction 1 point :
 Statement of objectives or aims of the experiment in the student’s own words.
 (not to be copied from the Lab Manual)
  • MATERIALS AND METHODS 0 points :

 from the procedures outlined in the Lab Manual. Specify which organisms were 
 used to create the phylogram.
  • RESULTS 4 points :
 A print out of the phylogram will suffice.
  • DISCUSSION 4 points :
 Responses to discussion questions.
  • SUMMARY |CONCLUSION 1 point :
 Two sentence summary of your findings.
  • REFERENCES 1 point :
 Credit is given for pertinent references obtained from sources other than the Lab Manual.
