Hypothesizing with onion cells.

Group: Hinerangi, Jahzara, and I

Aim: see onion cells on a microscope

Hypothesis: I reckon at 100X magnification we’ll be able to see the onion cells.

Equipment:

Microscope
onion
slide
cover slip
Tweezers
Blue dye

Method: We started with the slide. Then we pulled a thin layer of skin off of an onion with tweezers. We placed the onion skin onto the slide then put some saline onto it so that the blue stain would spread easily. Then we gently placed the cover slip onto the onion skin.

Observation: On the 10x microscope we saw the cells and they looked something like this.
On the 40x magnification we saw it a bit more zoomed in but there wasnt that much difference.

Then on the 100x magnification we could only see purple from the stain.

Conclusion: My hypothesis was wrong and we saw the onion cell in 10x magnification, then we saw it in 40x but we didn’t see it on 100x magnification.
