An experiment with some of these cells extracted from sea urchins showed that a surge of calcium ions through these cells preceded the formation of an envelope around them. These cells are produced by the archegonium in some plants. In humans, the zona pellucida surrounding this cell is hardened by the cortical reaction after being broken down by the acrosomes of another cell. During cytokinesis in animals, this cell receives most of the cytoplasm and thus results in the creation of polar bodies. The corpus luteum forms and secretes estrogen after this cell finishes developing in the ovarian follicle. For 10 points, identify this haploid cell which is fertilized by sperm.
