Examine onion cell slide

Today in science we had a practical experiment where we got to look at onion slides.

Equipment

The equipment you will need for this practical are Onion ,forceps ,knife, iodine ,cutting board ,microscope, cover slip ,slide and Dye

Method

1.First we got a cutting board and knife and cut the onion into 1/4.

2. Then each group got 1/4 each and we got the first layer of the onion.

3.Then we used our forceps to peel of a thin layer of the onion cells.

4.Then we put the layer of onion cells onto a slide.

5.Once we put the onion layer of cells onto the slide we put a few drops of iodine and dye onto the slide.

6.Once the iodine and dye was on the slide we put on the cover slip.

7.Then we let the slide sit for 1 minute.

9.Once that was done we put our slide underneath the microscope and took a look at the cells.
