Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The yeast lineage originated hundreds of millions of years ago, and 1,500 species are currently identified. They are estimated to constitute 1% of all described fungal species.
Cells can be classified as prokaryotic or ell aryotic. Prokaryotic cells, such as bacÂ­teria and archaea, lack a nucleus and mem brane-bound organelles. Eukaryotic cells, such as the cells of animals, plants, alga ,fungi, and protozoa, have internal, membrane-bound organelles, including true nuclei.Prokaryotic and eukaryotic cells have some common structural features such as external structures, cell walls, cytoplasmic membranes, and cytoplasm.External Structures of Prokaryotic Cells (pp. 60-65) The eternal structures of prokaryotic cells include glycocal ces, flagella, fimbriae, and pili.embranoLls Organelles Eukaryotic cells contain a variety of organelles that are surrounded by phospholipid bilayer membranes similar to the cytoplasmic membrane. Nucleus The nucleus is spherical to ovoid and is often the largest organelle in a cell. It contains most of the cell's genetic material in the form of DNA.
