egg cell

What we have now to understand by the ovum, the egg, or the egg-cell, is the microscopical germ which I have just described.

It contains the nucleus of the egg-cell (see fig. 23) and is called the cicatricula.

During the development of the egg-cell, food material is transferred from these cells through the pitted wall of the ovum.

Here, then (Fig. 29), we see the complex processes of karyokinesis in the first two stages of egg-cell division.
