Cheek Cells & Potato Starch Grains

I learned about cheek cells and potato starch grains.

First, I started with the cheek cells. It's easy for a beginner. All you have to do is to grab something to scratch your cheek(I uesed a fork), then scratch your inside part of your cheek. Get a slide, then put some water on it. Put the cell inside the water. After that, put dye. Then the coverslip. Actually, I've done quite well...

I did it on the magnification of 10x10. It wasn't as great as I thought. It was in all kinds of shapes but mostly circles. It was done in two circles, the outer one and the inner one. The outer one was covered in spots and the inner one was darker.

I pictured it too. It was my first time to picture, so it was fun.

I had a quick break and got ready for the potato starch grains. I got a potato and peeled off - this was only a part of the potato - next, scratched the inner part. I made a slide and looked into the microscope. But, oh dear, I only saw a black dot!!! I was looking for the cell but unluckily I realized that it was only the starch grains, I was disappointed but still, pictured it.
