Plants include any member of the kingdom Plantae, comprising multicellular organisms that typically produce their own food from inorganic matter by the process of photosynthesis and that have more or less rigid cell walls containing cellulose, including vascular plants, mosses, liverworts, and hornworts: some classification schemes may include fungi, algae, bacteria, blue-green algae, and certain single-celled eukaryotes that have plantlike qualities, as rigid cell walls or photosynthesis. Trees are plants and include any of a wide variety of perennial plants typically having a single woody stem, and usually branches and leaves. Many species of both gymnosperms (notably the conifers) and angiosperms grow in the form of trees. The ancient forests of the Devonian, Mississippian, and Pennsylvanian periods of the Paleozoic Era were dominated by trees belonging to groups of seedless plants such as the lycophytes. The strength and height of trees are made possible by the supportive conductive tissue known as vascular tissue .

Cypress of Abarkuh in Iran The Zoroastrian Sarv also known as Sarv-e Abarqu or Cypress of Abarkuh, is a cypress tree in Central Iran, Yazd Province at Iranian National Movement. It is said to have lived for 4000 years, earning its title as the oldest living thing in the whole of Asia. JŌMON SUGI Jōmon Sugi is a large Cryptomeria tree of about 83-foot height and 53-foot girth, located on Yakushima, in Japan. It dates to the Jomon Period from which it gets its name. Calculated using tree’s growth ring, it is about 2000 years old, though some argue that the tree is over 7000 years old. LLANGERNYW YEW IN WALES Llangernyw yew is the oldest tree in Wales, as it is over 4,000-year-old.
Scientists have published their first global assessment of the state of the world's plants.
They warn that 21% of all plants are at risk of extinction and face a broad range of threats. The research was carried out by the Royal Botanic Gardens Kew in the UK. See the full report: here
The nine most endangered plants in 2014 -Critically endangered plants
We've all heard about the most endangered animals. Creatures like the critically endangered black rhinoceros are famous, and in some cases have been reduced to just a handful of individuals. But what are the most endangered plants? They might not be as exciting or loveable as animals, but they are just as important to the ecosystem – and humanity relies on that ecosystem. Here are nine of the most threatened plants today. They are almost all classed as critically endangered by the International Union for Conservation of Nature (IUCN). These plants occupy some of the most inaccessible, remote parts of our planet. They are threatened by habitat destruction, illegal collection, poaching, and competition with invading species. Attenborough's pitcher plant (Nepenthes attenboroughii) Attenborough's pitcher plant is known only from the relatively inaccessible summit of Mount Victoria in Palawan in the Philippines. There are thought to be only a few hundred of them. Pitcher plants are carnivorous plants that trap animals in liquid-filled bowls called pitchers. Attenborough's pitcher plant is one of the biggest, with pitchers up to 30cm in height that can trap insects and rats. It was only discovered in 2007 when a team of botanists, tipped off by two Christian missionaries, scaled Mount Victoria. It is named after British natural history broadcaster David Attenborough.
