Part of the study on Fungi, we also observed yeasts reproducing.
Materials Needed:
* 1 T. Baker's yeast
* 1 T. sugar
* 2 C. warm water
* Methylene blue
* compound microscope
* depression slide
* cover slip
* cup or glass
* medicine dropper
Procedure:
1) In a glass, mix yeast, sugar and warm water. Allow the mixture to sit for about 10 minutes. You are waiting for the yeast cells to grow and multiply.
2)Using the medicine dropper, place a drop of the yeast mixture into the well of a depression slide. Add 1 drop of methylene blue stain. Place a cover slip over the sample and place on the microscope stage.
3) Focus on low power. Then, move to high power. Identify a reproducing cell and the tiny bubbles of carbon dioxide given off by the cells.
