Tolerance is the ability of plants to mitigate the negative fitness effects caused by herbivory.
 It is one of the general plant defense strategies against herbivores, the other being resistance, which is the ability of plants to prevent damage (Strauss and Agrawal 1999).
 Plant defense strategies play important roles in the survival of plants as they are fed upon by many different types of herbivores, especially insects, which may impose negative fitness effects (Strauss and Zangerl 2002).
 Damage can occur in almost any part of the plants, including the roots, stems, leaves, flowers and seeds (Strauss and Zergerl 2002).
 In response to herbivory, plants have evolved a wide variety of defense mechanisms and although relatively less studied than resistance strategies, tolerance traits play a major role in plant defense (Strauss and Zergerl 2002, Rosenthal and Kotanen 1995).
Denmoza is a genus of cactus found in Argentina, comprising only 2 species.
 The name of the genus is an anagram of the western province of Mendoza.
 These species grow slowly and stay globulous during a long period before becoming shortly column-shaped, 0.5 to 1.5 m high.
 The plant's diameter varies from 15 to 30 cm.
Olsynium (huilmo in Chile; formerly part of "Sisyrinchium") is a genus of summer-dormant rhizomatous perennials in the iris family, native to sunny hillsides in South America and western North America.
In biology, gonochorism ("Greek" offspring + disperse) or unisexualism or gonochory describes the state of having just one of at least two distinct sexes in any one individual organism.
 The term is most often used with animals, in which the individual organisms are often gonochorous.
 Gonochory is less common in plants.
 For example, in flowering plants, individual flowers may be hermaphrodite (i.e. with both stamens and ovaries) or gonochorous (unisexual), having either no stamens (i.e. no male parts) or no ovaries (i.e. no female parts).
 Among flowering plant species that have unisexual flowers, some also produce hermaphrodite flowers, and the three types occur in different arrangements on separate plants; the plants can be monoecious, dioecious, polygamomonoecious, polygamodioecious, andromonoecious, or gynomonoecious.
There are currently two main types of power plants operating in Nigeria: (1) hydro-electric and (2) thermal or fossil fuel power plants.
 With a total installed capacity of 8457.6MW (81 percent of total) in early 2014, thermal power plants (gas-fired plants) dominates the Nigerian power supply mix.
 Electricity production from hydroelectric sources (% of total) in Nigeria was reported at 17.59 % in 2014, according to the World Bank collection of development indicators, compiled from officially recognized sources.
 There have been two main types of fossil fuel/thermal power plants in the country: (i) coal-fired and (ii) natural gas-fired.
False vivipary is an abnormal condition found in many types of plants in which a plantlet is produced where the flower should appear.
 It is not a completely understood topic, but some say it could be caused by a hormonal mistake.
 The plantlet which appears can be rooted and grown like normal plants.
 This abnormal behavior can occasionally be seen in many types of carnivorous plants.
A trellis (treillage) is an architectural structure, usually made from an open framework or lattice of interwoven or intersecting pieces of wood, bamboo or metal that is normally made to support and display climbing plants, especially shrubs.
 There are many types of trellis for different places and for different plants, from agricultural types, especially in viticulture, which are covered at vine training systems, to garden uses for climbers such as grapevines, clematis, ivy, and climbing roses or other support based growing plants.
 The rose trellis is especially common in Europe and other rose-growing areas, and many climbing rose varieties require a trellis to reach their potential as garden plants.
 Some plants will climb and wrap themselves round a trellis without much artificial help being needed while others need training by passing the growing shoots through the trellis and/or tying them to the framework.
Silene menziesii is a species of flowering plant in the pink family known by the common names Menzies' campion and Menzies' catchfly.
 It is native to western North America from Alaska through the western half of Canada to the southwestern United States.
 It can be found in many types of habitat and it is quite common in much of its range.
 It is variable in morphology and there are a number of varied subtaxa.
 In general, it is a perennial herb growing from a caudex, appearing matlike, decumbent, or erect, with stems a few centimeters to over half a meter long.
 It is usually hairy in texture, with upper parts bearing sticky glandular hairs.
 The leaves are lance-shaped, oppositely arranged in pairs, and a few centimeters in length, upper leaves usually smaller than lower.
 Flowers may occur in a cyme at the top of the stem, or in leaf axils, or both.
 Each is encapsulated in a hairy, veined calyx of fused sepals.
 The petals are white with two lobes at the tips.
 The plant is dioecious with male and female plants producing different flowers.
 The male and female flower types look the same externally; the stamens are reduced in female plants and the stigmas are reduced in the male.
Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in Gymnosperms).
 There are two types of self-pollination: In autogamy, pollen is transferred to the stigma of the same flower.
 In geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) Gymnosperm.
 Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma.
 The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other types of self fertilization.
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.

Question: Are Denmoza and Olsynium both types of plants?
Answer: yes
