A Zygote is _______

Question

A zygote is _______.
A) another name for the corpus luteum
B) a tiny embryo consisting of four cells
C) a type of gamete
D) a fertilized egg

Accepted Answer

A zygote is a fertilized egg that results from the fusion of a sperm cell and an egg cell. It is the first stage of development for a new individual. Choice A is incorrect because the corpus luteum is a temporary gland that develops in the ovary after ovulation. Choice B is incorrect because a four-cell embryo is not yet a zygote. Choice C is incorrect because gametes are sex cells (sperm and egg) that fuse to form a zygote.
