  5. All of the structures within your mystery cell are called organelles. Plant and animal cells have quite a few common organelles. However, there are a few organelles that are unique to these two individual kinds of cells.

  6. You must determine which organelles belong to plant cells and which organelles belong to animal cells.

  12. Drawing upon all of the knowledge you have just gained about plant and animal cells, it is now time to carefully examine your mystery cell. Take a close look and identify all of the organelles you see.

  13. Look carefully!!!

  14. Is it plant or animal?

  15. Write a letter to your boss explaining your findings.

  16. Letter should include: • Identification of organelles • Omission of organelles • Reasons for classification • Justification of classification

  17. Your letter should be written in friendly format. If you need a reference, visit the following site: http://englishplus.com/grammar/00000144.htm
