I watched the video tutorial and I follow these steps.
I put a drop of methylene blue on a slide.
I placed a cover slip on gently. I want to avoid air bubbles at all cost.
I gently scrape the inside of my cheek with the flat side of a toothpick.
the picture above I used a medium lens marked ten with a magnification 100x
sides: membrane
nucleus: looks like a pupil
cell membrane: it’s like a sack
cheek cell: a big round spot
its a cheek cell on a power lens magnification 400x
it kind of looks like an eye
A cell membrane looks like a sack surrounding the nuclues
A cheek cell looks like an eye a regular spot
