Polarizing fucoid eggs drive a calcium current through themselves

KR Robinson and LF Jaffe

Calcium ions enter the prospective growth pole of polarizing Pelvetia eggs faster than the opposite pole and leave this antipode faster than the growth pole. The calcium current is greatest when first measured at 6 hours after fertilization and decreases as the time of final commitment to growth in a particular direction approaches.
