Verified step by step guidance1
Step 1: Understand the stages of human development during pregnancy. The process begins with fertilization, forming a zygote, which is a single-celled organism.
Step 2: The zygote undergoes multiple rounds of cell division (cleavage) and forms a blastocyst, which is a hollow structure that implants into the uterine wall.
Step 3: After implantation, the developing organism is referred to as an embryo. This stage lasts from implantation through the 8th week of pregnancy.
Step 4: After the 8th week, the developing baby is referred to as a fetus, which continues to grow and develop until birth.
Step 5: Based on the timeline provided in the question (implantation through the 8th week), the correct term for the developing baby is 'embryo'.
