meaning of words

When using homeostasis with another meaning it should be stated something like: In this article, homeostasis is...
Homeostasis is the regulation of "internal millieu", an aqueous bath outside the cells in animals. Yeasts like another microorganism does not regulate what is outside the cell. Therefore, microorganisms do not perform homeostasis it does perform cell regulation. However, I understand that after molecular biology anything goes.
