The egg cell from the white parent carries the factor for white, the pollen cell from the red parent carries the factor for red.
There is a large nucleus, but it is not always readily distinguished from the other contents of the egg cell.

Of the three cells of the “egg apparatus” the lower (o) one is the egg cell; the others are called “synergidæ.”
One of the nuclei, with the protoplasm immediately surrounding it, is called the egg cell.

In 1844 Koelliker discovered that the egg cell, by division and multiplication, becomes an aggregation—a heap of new cells.
