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.
In plant taxonomy, commelinids (originally commelinoids [1] [2]) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid.
The lists of cultivars in the table below are indices of plant cultivars, varieties, and strains. A cultivar is a plant that is selected for desirable characteristics that can be maintained by propagation. The plants listed may be ornamental, medicinal, and/or edible. Several of them bear edible fruit.
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.
Plants affected by mosaic disease experienced a decrease in phytolith size. This is because the virus constricts overall plant growth and therefore phytolith growth as well. Contrastingly, plants affected with bacterial wilt disease resulted in much larger phytoliths but they were abnormally shaped. This could be due to the bacteria causing ...
The selection of species to plant depends on various factors, such as the soil type, the position (sunny or shady location), the colour or effect that is required and the season of the year when the plants are required to flower. Border of tulips planted among pansies. Some examples of bulbous plant genera and their flowering season are given ...
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 ...
The two main mechanisms causing damage to recalcitrant seeds are desiccation effects on the intracellular structures and metabolic damage from the formation of toxic chemicals such as free radicals. [5] An example of the first type of damage would be found in some recalcitrant nontropical hardwood seeds, specifically the acorns of recalcitrant ...
