1. Introduction

 

  1. Back-round information 

The benedict reagent which is a blue colored solution containing ions is being used to test if simple sugars are present. Solutions that contain benedicts reagent and a reducing sugar when heated, copper II ions which are in the benedicts reagents are lessened to copper I ions

  1. Purpose:

Discovering cheek cell and the shapes of cheek cell.

  1. Question

What does the cheek cells look like?

  1. Hypothesis

Is the cheek cells shape circular? Or is their shape irregular?

2. Procedure

  1. Equipment’s used and the purpose of their use
  • Benedicts reagent
  • Test tube
  • Glucose solution
  • Water
  • Iodine
  • Starch solution
  • Biurette reagent
  • Egg white solution
  • Brown paper bag
  • Vegetable oil

 

  1.  List the procedure. 

  1. Use the dropper to drop water on the glass slide.

  2. Softly scratch your cheek from inside using the wooden stick.

  3. Mix the cell with the drop of water on the glass slide.

  4. Use the cover slip to cover the sample. Avoid the bubbles that may form                    from the air

  5. Place the glass slide under the microscope.

  6. Redo the procedure but this time use methylene blue rather than water.

  1. Results 

                    

 

4. Discussion

  1. Support the Hypothesis

When viewing cheek cells using a microscope, you should be able to see the qualities and features of eukaryotic cells. The usage of methylene blue is to reveal the shape of the cell membrane.

  1. Explanation the result

The cheek cells weren’t seen as clear when water was used, meanwhile the membrane bound nucleus was seen when the methylene blue was used, filled with mitochondrion surrounded by plasma.

  1. Conclusion

The shapes of the cells weren’t recognizable when water was used compared to when methylene blue was used.
