Bacteria, which are prokaryotic organisms, fall under the domain Bacteria. Fungi are eukaryotic and are classified under domain Eukaryota.
Gram staining reveals differences in the bacterial cell wall. The crystal violet dye used in Gram staining is retained by proteoglycan molecules in thick bacterial cell walls of Gram-positive bacteria. In contrast, Gram-negative bacteria with thin cell walls only retain the counterstain safranin.
Individual bacteria can be round (cocci), rod-shaped (bacilli), or spiral-shaped (spirilla).
Ascomycota are a type of fungi with a reproductive structure called an ascus. These organisms typically reproduce by asexual budding.
Basidiomycota are a type of fungi also known as the club fungi. They have a club-shaped reproductive structure called basidium and usually reproduce sexually.
