The Pre-embryonic period - Consists of the first two weeks in the forms: - Zygote (1 cell; diploid) - Morula (72 hours) - Blastocyst (5 days) Morula - At 72 hours of gestation - solid ball of 16-32 cells (called blastomeres) - the size of an ovum/zygote due to in favor of rapid cleavage division (for optimal surface area and waste removal) over growth. Blastocyst - 5 Days Gestation Features: - fluid filled cavity (blastocoel or blastocyst cavity) - inner cell mass (becomes the embryo)...
