What are two reasons why bacteria should not be classified as plants

Question

anonymous · Answer

Wait, Cyanobacteria, bacteria apart from Cyanobacteria, or all of them? There are lots of good reasons why regular non-Cyanobacteria bacteria aren't plants, but the decision to not classify Cyanobacteria with the plants was a pretty arbitrary one, as far as I know.

Plants could be classified as having roots, stems, and leaf structures, while most bacteria can't.

@Kainui But then algae wouldn't count either, or mosses for that matter (their leaf-like structures aren't real leaves).

kainui · Answer

Algae and mosses aren't classified as plants. I know. They don't have roots, stems, nor leaves.

Plants meaning angiosperms of course.

anonymous · Answer

Algae and mosses ARE plants (according to every definition I've ever heard), but they're not vascular plants. They are often referred to as "lower plants" or thallophytes.

anonymous · Answer

Angiosperms are indeed a huge and important group of plants, but within the line of land plants alone, you'll also find liverworts, hornworts, mosses, ferns, club mosses and gymnosperms.
