Explanation:

There are a few stages of embryo development:

1. Fertilization: this is where the female gamete (egg) meets with the male gamete (sperm) and they form a zygote

2. Blastocyst development: this is where the zygote divides into a ball of cells that eventually becomes the embryo inside a structure called the blastocyst; the blastocyst then travels up to the uterus.

3. Embryo development: this is where the embryo truly starts to develop in the uterus, growing the crucial body parts
