plant
plant Multicellular organism whose cells have cellulose cell walls and contain
chloroplasts or similar structures (plastids). They develop from
diploid embryos, and have a regular alternation of
haploid and diploid generations in their life cycle. Most plants are green and make their own food by
photosynthesis. A few are colourless
parasites or
saprophytes. Simple plants reproduce by means of
spores, while more advanced plants produce
seeds and
fruits. Plants show a wide range of biochemistry; some produce chemicals such as
alkaloids,
narcotics, and even cyanide; others secrete substances into the soil to prevent other plants growing near them. Many of these chemicals form the bases for the development of drugs. Plants are classified on the basis of their morphology (shape and structure). The most important phyla are: the Bryophyta (
bryophytes), which include the mosses and liverworts;
Lycopodophyta, or club mosses; Sphenophyta (
horsetails); Filicinophyta (
ferns); Cycadophyta (
cycads); Ginkgophyta (
ginkgo); Coniferophyta (
conifers); and Angiospermophyta (
angiosperms). See also
