bacteria [pl. of bacterium], microscopic unicellular prokaryotic organisms characterized by the lack of a membrane-bound nucleus and membrane-bound organelles. Once considered a part of the plant kingdom, bacteria were eventually placed in a separate kingdom, Monera.
Let's take a look at some of the common characteristics of these organisms. Members of the kingdom Fungi are eukaryotes, meaning they have complex cells with a nucleus and organelles. Most are multicellular, with the exception of single-celled yeast.asidiomycota is the division that encompasses mushrooms and other mushroom-like organisms such as puffballs and stinkhorns. And Deuteromycota are known as 'imperfect fungi' because they don't quite fit the standard characteristics of fungi. An example is Penicillium, from which the antibiotic penicillin is derived.
