Answer 1

A sac-like structure where a fertilized egg or zygote comes to grow into a baby is known as a uterus.

• Every month, the egg is released from the ovary and moved into the fallopian tube for fertilization.
• If fertilization occurs, the egg is transported to the sac-like structure known as the uterus, where it is implanted and the baby develops securely.
• First, the zygote develops into a solid ball of cells.
• The blastocyst is a hollow ball of cells that develops from the zygote.
• The blastocyst implants in the uterine wall, where it grows into an embryo linked to a placenta and surrounded by fluid-filled membranes.
