If calcium were removed from the tissue then the polarity will be established within the cell but polarity will be lost in the tissue.
<u>Explanation:</u>
Cell polarity is the cellular components like cytoplasm, plasma membranes and other various cell organelles in the asymmetric order.
The coordinated arrangement of this cell polarity in tissue plane is called as planar cell polarity (PCP).
Calcium is the major component in the tissues that helps in formation of bones and other parts of body, if it is removed then the polarity will not be seen in the tissue, but in the cell the polarity will be established.
