1. Studying different eukaryotic cells in the microscope
You need:
Light microscope, toothpick, slides, coverslip, water, human hair, dye liquor, red onion,
slides with plants- and human cells.
Studying finished slides of plants- and human cells
•choose a ready-made preparation of plant- or human cells
•add a slide on the stage and learn how to move the slide. Start with the smallest
magnification and set the best possible picture.
•draw a picture of what you can see
Make a preparation of human hair
•put a drop of water on a glass slide and add a hair in the drop
•add a coverslip
•set the best possible picture
Studying your own cells
•gently scrape the inside of the cheek with a toothpick
•apply the mixture of cells in a layer on a glasslide
•add 2-3 drops of the dye liquid at the cellsample and then add a coverslip. Wait 5
minutes.
•study the cellsample under the microscope.
•draw a picture of your cells and name the cellparts you can see
Studying cells of the red onion
•pull off a small piece of the red layer which exists between each layer of the onion
•place it in a drop of water on a glass slide
•add a coverslip and study the cells under a microcope.
•draw a picture of the onioncell and insert the name of the cellparts you can see
Write a complete lab.report where you also answer the following questions
2. What similarities can you find between plant cells and human cells?
What differences can you find between plant cells and human cells?
Which cell parts can you
see in the light microscope?
