The foetus completes its growth within the _____
Open in App
Solution
The correct option is B 22 pairs of chromosomes.
An ovum is produced in the ovary. From the ovary, it is released into the oviduct. Ovum is fertilised by the sperm to give rise to a zygote inside the oviduct. The zygote divides to form an embryo which is implanted into the uterus. Inside the uterus the umbilical cord is a tube-like structure that connects a fetus to the mother's placenta, providing oxygen and nutrient-rich blood and removing waste. The embryo completes its development inside the amnion. Amnion is a membranous covering formed by the embryonic cells during the early stages of growth. Amnion is filled with amniotic fluid which prevents dehydration and protects the growing embryo from mechanic shocks.
