Скачать или смотреть Under the Microscope: Active Yeast Cell (100x-400x)

In this "experiment" we will see yeast cells under the microscope.
For the experiment you will only need yeast, water, sugar, dropper and the microscope (container and tools are optional).

-You will first make sure the water is around 34° Celsius.
-Then add 5 grams of sugar and 5 grams of yeast. Stir.
-Then wait 5 minutes and take a small sample of water with a dropper.
-Put the sample in the slide and add a cover slip into it.
-Just watch it in the microscope and enjoy!

Safety precautions:
-lab coats
-Gloves (i used latex but vinyl ones are OK too)

WARNING: the yeast is stinky :P

Songs:
Better off Alone - Alice Deejay
Canon - Pachelbel

Yeast are eukaryotic micro-organisms that are fromt he fungi kingdom. Most yeast cell reproduce asexually by mitosis and many other do budding. By fermentation, the yeast species Saccharomyces cerevisiae converts carbohydrates to carbon dioxide and alcohols -- for thousands of years the carbon dioxide has been used in baking and the alcohol in alcoholic beverages. It is also extremely important as a model organism in modern cell biology research, and is one of the most thoroughly researched eukaryotic microorganisms. Researchers have used it to gather information about the biology of the eukaryotic cell and ultimately human biology. Other species of yeast, such as Candida albicans, are opportunistic pathogens and can cause infections in humans. Yeasts have recently been used to generate electricity in microbial fuel cells, and produce ethanol for the biofuel industry.

Because yeast reproduce asexually and need no partner, we can see them "reproduce" in the microscope when we give them the correct conditions.
