Scientific Method: Onion Cells

Aim: Find a clear picture of onion cells.

Hypothesis: I think that we will be able to see a clear picture of onion cells at a magnification of 100x

Equipment: 

• 1 Onion
• A slide
• A cover slip
• Tweezers 
• Blue stain

Method: The first thing we did was collect a thin layer of skin from the onion using tweezers, we then added it to our slide. After that we had to add a drop of saline to our slide that had our onion on it. After that we also had to add a drop of blue stain. Lastly we had to put a cover slip on top of our slide. Once we did that our slide was ready to look at.

Observation/Conclusion: Once we looked at it through the microscope, we tried the magnification of 4x. When we looked at it, it looked like a lot of lines connected with many small dots surrounding it. When we looked at it in the magnification of 10x I could already see it clearly. It looked like the pattern of honeycomb. It was connected together and the pattern it had looked a lot like purple honeycomb.

 

The onion cells we looked a lot like this.
