Saccharomyces cerevisiae is a round to oval shaped yellow-green yeast from the fungi kingdom. As a eukaryote it has membrane bound organelles, an enclosed nucleus with double stranded DNA and uses its mitochondria for cellular respiration. As a fungi it is heterotrophic and it's cell shape is determined by cell wall formation which contains the strong polysaccharide chitin. Ascomycota can reproduce sexually or asexually, with internal spores called ascus for sexual reproduction and external asexual spores called conidia and can be single cellular or multicelluar. As a member of the class saccharomycetes, S. cerevisiae are single-celled and produce an ascus during sexual reproduction but do not form fruiting bodies.
