However, these organisms are still often considered plants, particularly in popular contexts.Outside of formal scientific contexts, the term "plant" implies an association with certain traits, such as being multicellular, possessing cellulose, and having the ability to carry out photosynthesis..The Viridiplantae, the green plants – green algae and land plants – form a clade, a group consisting of all the descendants of a common ancestor.With a few exceptions among green algae, the green plants have the following features in common; cell walls containing cellulose, chloroplasts containing chlorophylls a and b, and food stores in the form of starch contained within the plastids.They are not close relatives of the Archaeplastida, presumably having acquired chloroplasts separately from ingested or symbiotic green and red algae.
Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms.
Viridiplantae encompass a group of organisms that have cellulose in their cell walls, possess chlorophylls a and b and have plastids that are bound by only two membranes that are capable of storing starch.
It is this clade that is mainly the subject of this article (e.g., Plantae Plants in a broad sense comprise the green plants listed above plus Rhodophyta (red algae) and Glaucophyta (glaucophyte algae).
Plants are one of the two groups into which all living things were traditionally divided; the other is animals.
The division goes back at least as far as Aristotle (384 BC – 322 BC), who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food.
