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 tendency for people of one race to have difficulty identifying members of a race other than their own. Egocentric bias: Recalling the past in a self-serving manner, e.g., remembering one's exam grades as being better than they were, or remembering a caught fish as bigger than it really was. Euphoric recall
Ants are the best-known example of such a superorganism. A superorganism can be defined as "a collection of agents which can act in concert to produce phenomena governed by the collective", [ 2 ] phenomena being any activity "the hive wants" such as ants collecting food and avoiding predators , [ 3 ] [ 4 ] or bees choosing a new nest site.

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.
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 ...
But compared with most fibres, sclereids are relatively short. Characteristic examples are brachysclereids or the stone cells (called stone cells because of their hardness) of pears and quinces (Cydonia oblonga) and those of the shoot of the wax plant (Hoya carnosa). The cell walls fill nearly all the cell's volume.
Animals have senses, are able to move, and have physical appetites. The apex predator like the lion, could move vigorously, and has powerful senses like keen eyesight and the ability to smell their prey from a distance, while a lower order of animals might wiggle or crawl, or like oysters were sessile, attached to the sea-bed. All, however ...
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]
