Intrudtion about plant classification
Answers
Taxonomists, at least in the traditional Linnaeus method for classifying plants, separate the plantae kingdom into four major groups, or divisions, including: mosses and liverworts, which have no proper root systems; ferns, which have proper roots and produce spores (specialized reproductive cells rather than conventional seeds); coniferous trees, which have root systems and needle-shaped leaves and cones; and flowering plants, which have root systems and flowers that produce seeds. The dominant division in many biomes (that is, biotic communities, for instance, our deserts), with a quarter of a million species, is that of the flowering plants. Depending on the method they follow, taxonomists may divide the flowering plants – the most recently evolved of the botanical divisions – into two broad groups, or classes.
According to Wikipedia, one class, the “monocot,” produces a single first, or “embryonic,” leaf from its seed. Typically, its leaves have parallel veins, and its stems have vascular bundles (the water-conducting vessels) that occur in a random pattern in cross section. It produces flowers with parts that occur in multiples of three—for instance, three, six or nine petals.
