Yeasts are single-cell eukaryotes, cell wall composition and plant cell wall is not the same, the main component of dextran and mannan. DNA exists in the nucleus and mitochondria, in addition, some yeasts also have plasmid DNA. In the ecosystem, most yeasts live in saprophytic organisms and belong to decomposers; a few parasites belong to consumers, such as yeasts on the surface of fruits. Questions on the yeast representative, typical, comprehensive and strong, in a variety of examinations have their knowledge of the test design, the following questions on the yeast analysis. First, to test the way the curve of respiratory effects
