Aristotle divided all living things between plants, which generally do not move, and animals. In Linnaeus' system, these became the Kingdoms Vegetabilia (later Plantae) and Animalia. Since then, it has become clear that the Plantae as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms. However, these are still often considered plants in many contexts. Indeed, any attempt to match "plant" with a single taxon is doomed to fail, because plant is a vaguely defined concept unrelated to the presumed phylogenic concepts on which modern taxonomy is based.
When the name Plantae is applied to a specific taxon, it is usually one of three groups, each more inclusive than the last. From smallest to largest these are
* Land plants (also known as Embryophyta) - see below
* Green plants (also known as Viridiplantae or Chlorobionta) comprising Embryophytes and green algae. Essentially the subject of this article.
* Primoplantae (also known as Plantae sensu lato, Plastida, or Archaeplastida) comprises green plants, red algae and glaucophyte algae. The broadest plant clade, this comprises the eukaryotes that acquired their chloroplasts directly by engulfing bacteria.
Informally, other creatures that carry out photosynthesis are called plants as well, but they do not constitute a formal taxon.

Most terrestrial plants (both bryophytes and tracheophytes) share some general structural and functional features. Plant bodies are divided into two regions, the underground root portion and the aerial shoot portion (including stem, leaves, flowers, and fruits). These different regions of the plant are dependent on each other, as each performs different essential functions. Land plants also share certain more specific adaptations that are essential to survival out of water. These include an impermeable waxy cuticle on the outer aerial surfaces, jacket cells around the reproductive organs, and stomata that allow gas exchange without risking excessive water loss.
Plants are also autotrophic, meaning that they produce their own food and do not use other organisms to supply organic nutrients the way animals do. Finally, the life cycle of plants follows a pattern called the alternation of generations, in which they fluctuate between haploid and diploid generations and sexual and asexual modes of reproduction.

General Characteristics of Plants: 1.A plant is a multicolor, eukaryote organism with cellulose-rich cell walls and chloroplasts that has starch as the primary carbohydrate food reserve. Plants are primarily terrestrial, autotropic (capable of making their own food) organisms. Most plants contain chlorophyll's a and b and xanthophylls (yellow pigments) as well as carotene's (orange pigments). 2.Cellulose 3.Plants can reproduce sexually or asexually. Sexual reproduction involves the male pollen grains travel ling to the stigma of a flower, the pollen grain germinated and grows down the style and fertilizes the ovules held in the ovary of the flower. The fertilized ovule becomes an embryo (or zygote), a seed coat forms around the ovule and the ovary ripens into a fruit. At some point the seeds are dispersed from the fruit and will germinate if conditions are right. Asexual reproduction involves the production of a new plant without the use of flowers. this can be in the form of bulb-lets or rhizomes giving rise to new plants, or offset, runners (such as strawberry plants); new plants with complete root systems are generated that can stand alone form the "parent" plant. 4.From the soil it gathers nutrients up through the roots and to all parts of the plant that need it. 5.Yes.Their closest relatives are the green algae and land plants. . 6. All plants possess a cuticle, a waxy covering on aerial parts that reduces drying or dessication.
