malian species, with 11,733 recognized species of reptiles compared to 5,884 extant mammals. Along with the

species diversity, reptiles have diverged in terms of external morphology, from limbless to tetrapod gliders to armored

chelonians, reflecting adaptive radiation to a diverse array of environments.Morphological differences are reflected in the nervous system phenotype, such as: absence of lateral motor column

asmic streaming, also called protoplasmic streaming and cyclosis, is the flow of the cytoplasm inside the cell, driven by forces from the cytoskeleton. It is likely that its function is, at least in part, to speed up the transport of molecules and organelles around the cell. It is usually observed in large plant and animal cells, as well as amebae, fungi and slime molds. It is seen in cells greater than approximately 0.1 mm. In smaller cells, the diffusion of molecules is more rapid, but diffusion slows as the size of the cell increases, so larger cells may need cytoplasmic streaming for efficient function. The green alga genus Chara possesses some very large cells, up to 10 cm in length, and cytoplasmic streaming has been studied in these large cells. Cytoplasmic streaming is strongly dependent upon intracellular pH and temperature. It has been observed that the effect of temperature on cytoplasmic streaming created linear variance and dependence at different high temperatures in comparison to low temperatures. This process is complicated, with temperature alterations in the system increasing its efficiency, with other factors such as the transport of ions across the membrane being simultaneously affected. This is due to cells homeostasis depending upon active trans
