Yeast-Budding
 

Stained yeast appear as green, red, and purple on the sample slide. These yeasts are too tiny to be seen at 40x. But, it is clear that the shapes of yeasts are various. The yeasts are consisted of multiple spores. The yeasts are reproduced asexually by budding or fission. As name given to the slide, these types of yeast shown in the slide are produced by budding. But, a few types of yeast are produced sexually. Here is a picture describing budding and fission reproduction. Ohio State University provides an diagram that explains fission and budding reproductions.

Some yeast species are used in fermenting alcohols. Also, yeasts are extremely important in cell biology research, and are "the most thoroughly researched eukaryotic microorganism, which gathers information into the biology of the eukaryotic cell and ultimately human biology"<Wikipedia>. Some yeasts can cause infection in humans.

Honestly, there are not much interesting things to explain about details of yeast. I organized the pictures of yeast according to colors of the yeast. However, there are not much differences in each yeast.

Purple Yeast Image Data Description 1000x There are a few spores visible inside of the yeast. These spores appear to be black. 1000x This picture is cropped from the previous picture in order to show more detailed purple yeast. Individual spores appear to be bigger. Green Yeast Image Data Description 1000x This yeast, stained in green, doesn't seem to have many spores. Its size is smaller than the purple yeast. It seems to be a bigger yeast with more spores. 1000x Individual green-stained spores are visible. Some spores are darker than others. Red Yeast Image Data Description 1000x Interestingly, this red yeast is almost same size as the green yeast, but it seems to have much more spores. 1000x Honestly, it was hard to focus on this red yeast because of its intense three-dimensionality. However, this red yeast appears to be bigger and more detailed.
