Is saccharomyces cerevisiae a eubacteria or a archaebacteria?

Answer 1

It is a eubacteria.

Both eubacteria and archaebacteria are prokaryotes that have no organized nucleus and no membrnae bound organelles. The difference between the two is that archae bacteria tend to live in extreme conditions such as hydrothermal vents that can get up to 95°C, in very acidic or salty environments, places with no oxygen, and a wide array of places as such.

Archaebacteria usually fall under one of three categories: mathanogens (organisms that convert carbon dioxide to methanol), thermophiles (organisms that can live in very hot and acid environments), or halophiles (organisms that tend to live in extremely salty environments such as the Dead Sea).

As saccharomyces cerevisiae (yeast) doesn't fall under any of these categories, it is a eubacteria. It is a fungus, and in most cases, fungi will always be eubacteria.

Answer 2

Saccharomyces cerevisiae is a type of fungi, specifically a yeast. It belongs to the domain Eukaryota, not to the domains Eubacteria or Archaebacteria.
