Polar body, Polar cell, or Polar globule (Biol.), a

separation from the ovum. Each of the polar bodies removes
maternal chromatin from the ovum to make room for the
chromatin of the fertilizing spermatozoon; but their
functions are not fully understood.

Polar clock, a tube, containing a polarizing apparatus,
turning on an axis parallel to that of the earth, and

which are the extremes in a species, as white and black in
colors; hence, as great an opposition or contrast as
possible.
Polar projection. See under Projection.
