Therefore, electrophoresis of positively charged particles or molecules is sometimes called cataphoresis, while electrophoresis of negatively charged particles or molecules (anions) is sometimes called anaphoresis.
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.
Although plants produce numerous copies of the same organ during their lives, not all copies of a particular organ will be identical. There is variation among the parts of a mature plant resulting from the relative position where the organ is produced. For example, along a new branch the leaves may vary in a consistent pattern along the branch.
Santalales is ecologically diverse and includes free-living plants, such as Erythropalum, as well as (hemi)parasites. Among the latter are species that parasitize stems or shoots, such as the mistletoes of the genus Misodendrum , and root parasites, including the well-known and economically important sandalwood tree ( Santalum album ), whose ...
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.
An example of the first type of damage would be found in some recalcitrant nontropical hardwood seeds, specifically the acorns of recalcitrant oaks, which can be stored in a non-frozen state for up to two years provided that precautions are taken against drying.
The family Campanulaceae (also bellflower family), of the order Asterales, contains nearly 2400 species in 84 genera of herbaceous plants, shrubs, and rarely small trees, often with milky sap. [2] Among them are several familiar garden plants belonging to the genera Campanula (bellflower), Lobelia , and Platycodon (balloonflower).
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 ...
