Cellular Polarity

Cells do this both during maintenance and growth, locating replacements with nicety, and during development, producing a closely choreographed rearrangement of many or all the cellular components. The control of this choreography is virtually a mystery" (33). Many environmental factors influence cells and organisms polarly, such as light, gravity, and adj acent cells. Correspondingly, most cells and organisms have an intrinsic polar organization. Time also has a 'direction; therefore developmental processes often are vectorial and result in polar growth.
