In the most generally used sense, a plant is a member of the lower or vegetable order of living organized things; the term is also popularly applied to the smaller herbaceous plants, thus excluding trees and shrubs.
The early use of the word is for a twig, shoot, cutting or sapling, which was the meaniiig of Lat.
Other meanings of plant are derived from the verb to plant Lat. It is thus used of the fixtures, machinery, apparatus necessary for the carrying on of an in. In the following sections the botanical sense of the word is followed, the term being used generally as opposed to animals. The plant world falls into two great divisions, the higher or flowering plants Phanerogamscharacterized by the formation of a seed, and the lower or flowerless plants Cryptogamsin which no seed is formed but the plants are disseminated by means of unicellular bodies termed spores.
The term Cryptogam is archaic, implying a hidden method of reproduction as compared with the obvious method represented by the flower of the Phanerogam; with the aid of a good microscope it is, however, easier to follow the process of fertilization.
These two great divisions are moreover of unequal value, for the Cryptogams comprise several groups differing from each other by characters as marked as those which separate some of them from the Phanerogams.
The following groups or sub-kingdoms are those which are now generally recognized: Thallophyta are the most lowly organized plants and include a great variety of forms, the vegetative portion of which consists of a single cell or a number of cells forming a more or less branched thallus.
They are characterized by the absence of that differentiation of the body into root, stem and leaf which is so marked a feature in the higher plants, and by the simplicity of their internal structure. Both sexual and asexual reproduction occur, but there is usually no definite succession of the two modes, marking that alternation of sexual generation gametophyte and asexual generation sporophyte which characterizes the higher groups.
The group has until recent years been regarded as comprising three classes distinguished by well-marked physiological featuresthe Algae including the Seaweeds which contain chlorophyll, the Fungi which have no chlorophyll and therefore lead a saprophytic or parasitic mode of life, and the Lichens which are composite organisms consisting of an alga and a fungus living together in a mutual parasitism symbiosis ; Bacteria were regarded as a section of Fungi.
Such a system of classification, although convenient, is not the most natural one, and a sketch of the system which better expresses the relationships between the various subdivisions is given here. The study of phylogeny has suggested fourteen classes arranged in the following sequence: Thus simple forms included in the Heteroconteae, Chlorophyceae and Phaeophyceae show an obvious connection with the Flagellatae; the Peridineae may be regarded as a further developed branch; the Conjugatae and Diatomaceae cannot be directly connected; the origin of the Rhodophyceae is also obscure; while the Characeae are an advanced and isolated group see ALGAE.
The Mycetozoa or Myxomycetes are a saprophytic group without chlorophyll, of simple structure and isolated position. Owing to the similarity of structure and mode of life it is convenient to treat the Lichens q. The Bryophyta and Pteridophyta have sprung from the higher Thallophyta, and together form the larger group Archegoniatae, so-called from the form of the organ archegonium in which the egg-cell is developed.
The Archegoniatae are characterized by a well-marked alternation of gametophyte and sporophyte generations; the former bears the sexual organs which are of characteristic structure and known as antheridia male and archegonia female respectively; the fertilized egg-cell on germination gives rise to the spore-bearing generation, and the spores on germination give rise directly or indirectly to a second gametophyte.
The Mosses and Liverworts see BRYOPHYTA include forms with a more or less leaf-like thallus, such as many of the liverworts, and forms in which the plant shows a differentiation into a stem bearing remarkably simple leaves, as in the true mosses.
They have no true roots, and their structure is purely cellular or conducting bundles of a very simple structure are present. The independent plant which is generally attached to the soil by hair-like structures is the sexual generation, the sporophyte is a stalked or sessile capsule which remains always attached to the gametophyte from which it derives the whole or part of its nourishment.
In general structure they approach the Phanerogams with which they form collectively the Vascular Plants as contrasted with the Cellular PlantsThallophyta and Bryophyta.
The gametophyte is a small thalloid structure which shows varying degrees of independence affording an interesting transition to the next group. Sper,nelo phyla are characterized by an extreme reduction of the gametophyte generation. The sporophyte is the plant which is differentiated into stem, leaf and root, which show a wonderful variety 01 form; the internal structure also shows increased complexity and variety as compared with the other group of vascular plants, the Pteridophyta.Download this file.
