A plant community (sometimes "phytocoenosis" or "phytocenosis") is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types.
 The components of each plant community are influenced by soil type, topography, climate and human disturbance.
 In many cases there are several soil types within a given phytocoenosis.
A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete.
 Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement.
 There are two main types of concrete plants: "Dry mix" plants and "Wet mix" plants, and also plants that contain both a transit mix side and a central mix side while utilizing common material storage points.
 A concrete plant can have a variety of parts and accessories, including: mixers (either "tilt drum" or "horizontal" or in some cases both), cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors.
Frailea is a genus of globular to short cylindrical cacti native to Brazil.
 These species are cleistogamous.
 They were first classified in the genus "Echinocactus".
Cyathodes petiolaris is a small alpine plant in the heath family, found in Tasmania, Australia.
Claybank Brick Plant was a brickworks factory for the manufacturing of bricks from clay located with a quarry for clay on site.
 The Claybank Brick plant has been conserved as a part of Saskatchewan's industrial heritage with its official announcement June 29, 1997 as a National Historic Site of Canada by Minister of Canadian Heritage Sheila Copps.
 $2 million for the conservation and presentation of the Brick Plant by Claybank was contributed jointly between Federal and Provincial Government funding departments.
 Claybank Brick Plant used neighboring clay from the Massold Clay Canyons.
 The Cretaceous period resulted in the "Whitemud Formation" which is the underlying zone of the Claybank Hills.
 The Whitemud Formation is noted for two main types of clay; white and grey in colour which possess different properties.
 Also close to Claybank are the Dirt Hills where a "bentonitic clay" can be found.
 Therefore, the brick produced is used for different purposes.
 Claybank Brick Plant is known for its face brick, as well as tiles, fire brick, insulating brick
The Sawyer and Keeler-Wolf classification system is an evolving system of classification of vegetation types, plant communities, or floristic characterization.
 It was first developed in 1995 by John O. Sawyer and Todd Keeler-Wolf for the California Native Plant Society, in the mission to classify all vegetation in California.
 Particular attention was paid to recognizing rare types that were "lumped" into general categories in previous systems, such as the Munz and Keck classification system, Chetham and Haller classification system, and Holland classification system.
 It uses constantly updated quantitative measurements of both species diversity and cover to define its types.
 It intended to be evolving and to continue to be refined.
The Global Plant Clinic (GPC) is managed by CABI in alliance with Rothamsted Research and FERA Science.
 The GPC provides plant health services and supports over 80 plant health clinics in Africa, Asia and Latin America.
 The clinic has a diagnostic service, which covers all plants and types of problems, is used by over 80 countries and helps maintain disease vigilance.
 The clinic also trains plant pathologists, and work with all sectors to improve regular and reliable access to technical support and advice.
 The clinics main aim is to create durable plant health services for those who need them most by improving access to technical support and advice.
Cyathodes is a genus of shrubs within the heath family.
 A characteristic feature of the genus is a deeply five-cleft calyx.
Somatic embryogenesis is an artificial process in which a plant or embryo is derived from a single somatic cell or group of somatic cells.
 Somatic embryos are formed from plant cells that are not normally involved in the development of embryos, i.e. ordinary plant tissue.
 No endosperm or seed coat is formed around a somatic embryo.
 Applications of this process include: clonal propagation of genetically uniform plant material; elimination of viruses; provision of source tissue for genetic transformation; generation of whole plants from single cells called protoplasts; development of synthetic seed technology.
 Cells derived from competent source tissue are cultured to form an undifferentiated mass of cells called a callus.
 Plant growth regulators in the tissue culture medium can be manipulated to induce callus formation and subsequently changed to induce embryos to form from the callus.
 The ratio of different plant growth regulators required to induce callus or embryo formation varies with the type of plant.
 Somatic embryos are mainly produced "in vitro" and for laboratory purposes, using either solid or liquid nutrient media which contain plant growth regulators (PGR’s).
 The main PGRs used are auxins but can contain cytokinin in a smaller amount.
 Shoots and roots are monopolar while somatic embryos are bipolar, allowing them to form a whole plant without culturing on multiple media types.
 Somatic embryogenesis has served as a model to understand the physiological and biochemical events that occur during plant developmental processes as well as a component to biotechnological advancement.
 The first documentation of somatic embryogenesis was by Steward et al. in 1958 and Reinert in 1959 with carrot cell suspension cultures.
Plant functional types (PFTs) is a system used by climatologists to classify plants according to their physical, phylogenetic and phenological characteristics as part of an overall effort to develop a vegetation model for use in land use studies and climate models. PFTs provide a finer level of modeling than biomes, which represent gross areas such as desert, savannah, deciduous forest.
 In creating a PFT model, areas as small as 1 km are modeled by defining the predominant plant type for that area, interpreted from satellite data or other means.
 For each plant functional type, a number of key parameters are defined, such as fecundity, competitiveness, resorption (rate at which plant decays and returns nutrients to the soil after death), etc.; the value of each parameter is determined or inferred from observable characteristics such as plant height, leaf area, etc.

Question: Are Frailea and Cyathodes both types of plant?
Answer: yes
