No, would not consider.
Bacteria and yeast cannot be considered as plants as bacteria belongs to the Kingdom Monera while yeast belong to Kingdom Fungi. The category under which plants fall is Kingdom Plantae. They are eukaryotic, autotropic and multicellular entities. Both yeast and bacteria are unicellular. Bacteria are prokaryotes, that is to say, that the membrane-bound nucleus is absent. Consequently, yeast and bacteria cannot be categorized as plants as they do not have the characteristics that are commonly found in plants.
