Question
The zygote divides to form __________ which is implanted in uterus.
Solution
The zygote divides to form blastocyst, which is implanted in uterus.
Explanation:
The mitotic division starts as the zygote moves through the isthmus of the oviduct called cleavage towards the uterus and forms 2, 4, 8, 16 daughter cells called blastomeres. The embryo with 8 to 16 blastomeres is called a morula. The morula continues to divide and transforms into blastocyst as it moves further into the uterus.
