Carefully place a coverslip to avoid air bubbles 4. Observe your slide under 4X power - draw what you see - identify label cell parts -. The Human Cheek Cell.

Put a drop of methylene blue on a slide. Methylene bluewill stain clothes and skin. Gently scrape the inside of your cheek with the flat side ofa toothpick.

1Put a drop of methylene blue on a slideCaution. Methylene blue will stain clothes and skin. Gently scrape the inside of your cheek with the flat side of a toothpickScrape lightly.

Stir the end of the toothpick into the stain and throw the toothpick away. Cheek cell lab. ___________________The Human Cheek Cell 1.

List the 3 parts of the Cell Theory 2. Write a short description of each of the following. All organisms are made of one or more cells.

The cell is the basic unit of all living things. All cells come from existing cells. Protective layer that covers the cell and acts as a barrier.

The fluid that holds all of the contents in the cell. Take a clean cotton swab and gently scrape the inside of your mouth. Smear the cotton swab on the centre of the microscope slide for 2 to 3 seconds.

Add a drop of methylene blue solution and place a coverslip on top. Concentrated methylene blue is toxic if ingested. DNA Extraction from Human Cheek Cells.

DNAyou hear about it all the time. DNA is used every day by scientists and lawyers to help in criminal investigation paternity suits cloning etc. Your DNA is your genetic fingerprintthis means that your DNA is like no one elses in the world.

The procedure that we will. The cheek cells are surrounded with saliva and salvia is transparent just like water. If one were to spot the onion cell with water it would be more difficult to spot this cell.

The plant cell will look sort of like a rectangle but not a perfect rectangle because it has a cell wall. To Prepare Stained Temporary Mount of Human Cheek Cells Materials Required. Gently scrape the inner side of the cheek using a toothpick which will collect some cheek cells.

Place the cells on a glass slide that has water on it. Mix the water and the cheek cells. Cheek Cell Lab Name The Human Cheek Cell Procedure Put A Drop Of Membrane 1 Go To Google And Type Cheek Cells Into The Search Box Virtual Microscope Lab Cheek Cells Name.

Place the edge of a paper towel on any solution outside of the cover slip to absorb the excess moisture. Mount the human cheek cell slide on the light microscope viewing platformPull excess dye and water out from underneath the cover slip by allowing a blotting paper to absorbe water. 2 pages 873 words.

Viewing Human Cheek Cells. In this lab we took a sample of our own cells by scraping the inside of the cheek with a toothpick. The sample was then stained with methylene blue so the cells could be viewed at 40x 100x and 400x.

The following images simulate what would be seen at each magnification. As in all animal cells the cells of the human cheek do not possess a cell wall. A cell membrane that is semi-permeable surrounds the cytoplasm.

Unlike plant cells the cytoplasm in an animal cell is denser granular and occupies a larger space. The vacuole in an an animal cell. Kaylah Brown Title.

Visualizing cheek cells Purpose. The purpose of this lab is for the students to learn how to use the microscope to view their individual cheek cells Hypothesis. If the cheek cells are eukaryotic then a nucleus will be visible when viewing the cells through the microscope Materials.

Microscope Tooth pick Methylene blue solution Cover slip Slides Pencil Paper Paper towel Procedure. Step 1 First obtain a microscope beneath the lab. Use the flat side of a toothpick to gently scratch the inside of your cheek.

DO NOT GOUGE YOUR CHEEK - you dont need chunks of skin and definitely dont want to draw blood. Gently swish the toothpick in the drop of dye on the slide. Some of your cheek cells should drift off into the dye.

Throw the toothpick away. The Human Cheek Cell. Write a short description of each of the following–cell membrane–cytoplasm–nucleus–organelle.

1Gently scrape the inside of your cheek with the flat side of a toothpick. Rub the toothpick on a clean slide. Add a small drop of water and cover with a cover slip.

Cheek Cell Lab. PurposeTo find out what an animal cells look like under a microscope. HypothesisIf I look at my cheek cell scraping under a microscope and put iodine on it then I will see the different parts of the cell including the nucleus cytoplasm and cell membrane.

To Prepare Stained Temporary Mount of Human Cheek Cells Materials Required. Gently scrape the inner side of the cheek using a toothpick which will collect some cheek cells.

Place the cells on a glass slide that has water on it. Mix the water and the cheek cells. Cheek cells are epithelial cells that line the interior surface of our mouths.

The base layer of cells in an epithelial structure are not actually cells but a sticky layer on which the cells anchor. The other surface of the epithelial cell touches the outside world like skin or an open space like the mouth. Animal cell to be studied in lab.

The cells are flat and irregular in shape with no cell wall. The nucleus can be seen very prominently in the center of the cell. The nucleus of the cell is stained easily with the methylene blue stain.

The cell membrane and the cytoplasm can also be studied through these cells. Functions of the Organelles. Obtain a small amount of cell lysis solution from the front counter using your small beaker.

At your lab station measure 2 mL of cell lysis solution into a graduated cylinder. Holding your test tube at an angle carefully add the 2mL of cell lysis solution to your test tube that should already contain your collected cheek cells. The Human Cheek Cell.

List the 3 parts of the Cell Theory. Living things are made of cells. Can only come from other cells.

Cells are the basic unit of structure and function. Describe or define each of the following. Outer boundary of the cell.

Fluid within the cell. Control center of the cell.
