LAB: OBSERVING CELLS
Your Task: Write a Formal Lab Report.
Note: Discussion questions (1 – 4) are as follows.
1. What cell organelles were stained by methylene blue in cheek cells?
2. What cell organelles were you unable to find? Suggest two possible reasons for
this.
3. Describe the colour and shape of tomato chromoplasts, and their size relative to
the nucleus.
4. Summarize in chart form the similarities and differences between plant and
animal cells based on what you examined in this lab. Include differences in cell
sizes in your answer.
