Sclereids in a diffuse pattern are dispersed throughout the leaf tissue, and sclereids in a terminal pattern are concentrated about the tips of leaf veins. Sclereid formations in leaves include the branched sclereids of Trochodendron , the columnar sclereids of Hakea , and the hair-like trichosclereids that branch into air chambers within the ...
The Spiralia are a morphologically diverse clade of protostome animals, including within their number the molluscs, annelids, platyhelminths and other taxa. [4] The term Spiralia is applied to those phyla that exhibit canonical spiral cleavage , a pattern of early development found in most members of the Lophotrochozoa .
Cryptids are animals or other beings that cryptozoologists believe may exist somewhere in the wild, but whose present existence is disputed or unsubstantiated by science. Cryptozoology is a pseudoscience and has been widely critiqued by scientists.
The concept of many plants and animals coexisting together, having an ecosystem and building upwards was the theory he aimed for (example: rain forest). The general theory later failed due to the fact that there was little or extremely basic comparable information about the logic of a being, the concept worked more in favor towards smaller ...
Sclereids are irregularly shaped cells that add compression strength [10] but may reduce flexibility to some extent. They also serve as anti-herbivory structures, as their irregular shape and hardness will increase wear on teeth as the herbivores chew. For example, they are responsible for the gritty texture in pears, and in winter pears. [13]
Sclereids are variable in shape. The cells can be isodiametric, prosenchymatic, forked or elaborately branched. They can be grouped into bundles, can form complete tubes located at the periphery or can occur as single cells or small groups of cells within parenchyma tissues. But compared with most fibres, sclereids are relatively short.
Boreoeutheria (/ b oʊ ˌ r iː oʊ j uː ˈ θ ɛr i ə /, "northern eutherians") is a magnorder of placental mammals that groups together superorders Euarchontoglires and Laurasiatheria.
The animal becomes an allegory: the dove, for example, represents peace. [3] God's creature, the animal, helps man interpret the world, in a symbolic role, particularly represented in bestiaries. From the 13th century onwards, encyclopedias began to appear, partly due to the translation of Aristotle's works. The animal had its place in these ...
