Examples

The ovum of Amphioxus contains very little food material and its segmentation is quite uniform.
A section of the embryo, as we may now call the ovum, is represented in Plate 5, fig.
The bulk of the ovum is composed of yolk spherules, imbedded in a protoplasmic matrix.

The outer of the three is composed of the largest-sized yolk-spherules which constitute the greater part of the ovum.
