PlantPlants are eukaryotes, predominantly photosynthetic, that form the kingdom Plantae. Many are multicellular. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. All current definitions exclude the fungi and some of the algae. By one definition, plants form the clade Viridiplantae (Latin for "green plants") which consists of the green algae and the embryophytes or land plants. The latter include hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperms, and flowering plants.
FrankincenseFrankincense (also known as olibanum) is an aromatic resin used in incense and perfumes, obtained from trees of the genus Boswellia in the family Burseraceae. The word is from Old French franc encens ('high-quality incense'). There are several species of Boswellia that produce true frankincense: Boswellia sacra (syn. B. bhaw-dajiana, syn. B. carteri), B. frereana, B. serrata (B. thurifera, Indian frankincense), and B. papyrifera. Resin from each is available in various grades, which depends on the time of harvesting.
PolyesterPolyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing.
Bark (botany)Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm.
PaintPaint is a liquid pigment that, after application to a solid material, and allowed to dry, adds a film-like layer to protect, add color, or provide texture. Paint can be made in many colors—and in many different types. Most paints are either oil-based or water-based, and each has distinct characteristics. For one, it is illegal in most municipalities to discard oil-based paint down household drains or sewers. Clean-up solvents are also different for water-based paint than oil-based paint.
CopalCopal is a tree resin, particularly the aromatic resins from the copal tree Protium copal (Burseraceae) used by the cultures of pre-Columbian Mesoamerica as ceremonially burned incense and for other purposes. More generally, copal includes resinous substances in an intermediate stage of polymerization and hardening between "gummier" resins and amber. Copal that is partly mineralized is known as copaline. It is available in different forms; the hard, amber-like yellow copal is a less expensive version, while the milky-white copal is more expensive.
IncenseIncense is an aromatic biotic material that releases fragrant smoke when burnt. The term is used for either the material or the aroma. Incense is used for aesthetic reasons, religious worship, aromatherapy, meditation, and ceremony. It may also be used as a simple deodorant or insect repellent. Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses.
PineA pine is any conifer tree or shrub in the genus Pinus (ˈpiːnuːs) of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere.
Pitch (resin)Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, or plants. Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch is also known as resin. Rosin refers to pitch made from plant resin. Tar is sometimes used interchangeably with pitch, but generally refers to a more liquid substance derived from coal production or from plants. Pitch was traditionally used to help caulk the seams of wooden sailing vessels (see shipbuilding), and to coat earthenware vessels for the preservation of wine.
MyrrhMyrrh (mɜːr; from an unidentified ancient Semitic language, see § Etymology) is a gum-resin extracted from a number of small, thorny tree species of the genus Commiphora. Myrrh resin has been used throughout history as a perfume, incense and medicine. Myrrh mixed with posca or wine was widely used in many ancient cultures to produce pleasurable feelings and as an analgesic. When a wound on a tree penetrates through the bark and into the sapwood, the tree secretes a resin. Myrrh gum, like frankincense, is such a resin.
