Heliophytes or sunstroke plants are adapted to a habitat with a very intensive insolation by their structure and metabolism. Examples are mullein, ling, thyme and soft velcro, white clover, and most roses. They are common in open terrain, rocks, meadows, as well as at the mountain pastures and grasslands and other long sunny exposures. [1] [2]
Raunkiær's life-form scheme has subsequently been revised and modified by various authors, [6] [7] [8] but the main structure has survived. Raunkiær's life-form system may be useful in researching the transformations of biotas and the genesis of some groups of phytophagous animals.
In linguistics, anaphora (/ ə ˈ n æ f ər ə /) is the use of an expression whose interpretation depends upon another expression in context (its antecedent).In a narrower sense, anaphora is the use of an expression that depends specifically upon an antecedent expression and thus is contrasted with cataphora, which is the use of an expression that depends upon a postcedent expression.
The gymnosperms (/ ˈ dʒ ɪ m n ə ˌ s p ɜːr m z,-n oʊ-/ ⓘ nə-spurmz, -noh-; lit. ' revealed seeds ') are a group of woody, perennial seed-producing plants, typically lacking the protective outer covering which surrounds the seeds in flowering plants, that include conifers, cycads, Ginkgo, and gnetophytes, forming the clade Gymnospermae [2] The term gymnosperm comes from the ...
Associations between fungi and plant roots, wherein the fungus facilitates nutrient uptake (particularly nitrogen) by the plant in exchange for carbon in the form of sugars from the plant root. [2] There is a parallel example in marine environments of sponges on the roots of mangroves, with a relationship analogous to that of mycorrhizae and ...
With larger Fibonacci pairs, the pattern becomes complex and non-repeating. This tends to occur with a basal configuration. Examples can be found in composite flowers and seed heads. The most famous example is the sunflower head. This phyllotactic pattern creates an optical effect of criss-crossing spirals.
A hygrophyte (Greek hygros = wet + phyton = plant) is a plant that inhabits moist areas and is intolerant of dry conditions. [1] The species may inhabit wet and dark forests and islands, dense swamps, and wet meadows. Within the group of all types of terrestrial plants, they are least resistant to drought. [2] [3]
On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens , and these traits are not continuous. The morph phenotype is genetically linked to genes responsible for a unique system of self-incompatibility , termed heteromorphic self-incompatibility , that is, the pollen from a ...
