The Plants Portal

The leaf is usually the primary site of photosynthesis in plants.

Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses.

There are about 320,000 known species of plants, of which the great majority, some 260–290 thousand, produce seeds. Green plants provide a substantial proportion of the world's molecular oxygen, and are the basis of most of Earth's ecosystems. Plants that produce grain, fruit, and vegetables also form basic human foods and have been domesticated for millennia. Plants have many cultural and other uses, as ornaments, building materials, writing material and, in great variety, they have been the source of medicines and psychoactive drugs. The scientific study of plants is known as botany, a branch of biology. (Full article...)

Cirsium vulgare
Cirsium vulgare is a species of thistle in the plant family Asteraceae. Native to Europe and Western Asia, it has become naturalised in North America, Africa and Australia, and is an invasive weed in some areas. It is a ruderal species, able to colonise bare ground, but also persists well on pasture as its thorny leaves and stems make it unpalatable to most grazing animals. The flowers are rich in nectar, attracting bees and butterflies, and the seeds are a favourite with goldfinches, linnets and greenfinches. The downy pappus, which assists in wind dispersal of the seeds, is used by birds as nest-lining material.
