Formation of New Membranes

Divisions of the egg or blastomeres raise the total surface area of the two daughter cells to be covered via membrane at every cleavage. The parent cell's existing membrane is insufficient. From the proof available so far, it is pointed out that this insufficiency of membranes for daughter blastomeres during cleavage is build up from two sources:

i) A portion of the membranes that are covering the daughter cells is provided by stretching and extension of the original plasma membrane of the zygote or the blastomeres.

ii) A portion of the cell membrane is newly synthesized through the daughter cells. So, the furrow membranes are a mosaic of dissimilar parts.
