The plants portal
are a major group of life
forms and include familiar organisms
such as trees
, and green algae
. About 350,000 species
of plants, defined as seed plants
and fern allies
, are estimated to exist currently. As of 2004, some 287,655 species had been identified, of which 258,650 are flowering
and 15,000 bryophytes
. Green plants
, sometimes called metaphytes
, obtain most of their energy from sunlight
via a process called photosynthesis
Aristotle divided all living things between plants (which generally do not move), and animals (which often are mobile to catch their food). In Linnaeus' system, these became the Kingdoms Vegetabilia (later Metaphyta or Plantae) and Animalia (also called Metazoa). 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, both technical and popular. Indeed, an attempt to perfectly match "plant" with a single taxon is problematic, because for most people the term plant is only vaguely related to the phylogenic concepts on which modern taxonomy and systematics are based.
The flora of Scotland
is an assemblage of native plant species including over 1,600 vascular
plants, more than 1,500 lichens
and nearly 1,000 bryophytes
. The total number of vascular species is low by world standard but lichens and bryophytes are abundant and the latter form a population of global importance. Various populations of rare fern
exist, although the impact of 19th century collectors threatened the existence of several species. The flora is generally typical of the north west European
part of the Palearctic ecozone
and prominent features of the Scottish
flora include boreal Caledonian
forest (much reduced from its natural extent), heather moorland
and coastal machair
. There are a variety of important trees species and specimens; a Douglas Fir
is the tallest tree in the United Kingdom
and the Fortingall Yew
may be the oldest tree in Europe. The Shetland Mouse-ear
and Scottish Primrose (pictured)
flowering plants and there are a variety of endemic mosses and lichens. Conservation of the natural environment is well developed and various organisations play an important role in the stewardship of the country's flora. Numerous references to the country's flora appear in folklore, song and poetry.
