What is the process in which cells migrate to form the three primary germ layers called?

Gastrulation
B
Apoptosis
C
Mitosis
D
Meiosis
Verified step by step guidance1
Understand the context of the question: The problem is asking about a biological process where cells migrate to form the three primary germ layers. These germ layers are the ectoderm, mesoderm, and endoderm, which are crucial for embryonic development.
Review the term 'Gastrulation': Gastrulation is the process during embryonic development where cells rearrange and migrate to form the three primary germ layers. This process establishes the basic body plan of the organism.
Clarify why 'Apoptosis' is not correct: Apoptosis refers to programmed cell death, which is a different biological process unrelated to the formation of germ layers.
Clarify why 'Mitosis' is not correct: Mitosis is the process of cell division that results in two identical daughter cells. While mitosis is important for growth and development, it does not directly involve the migration of cells to form germ layers.
Clarify why 'Meiosis' is not correct: Meiosis is a type of cell division that reduces the chromosome number by half, producing gametes (sperm and egg cells). It is unrelated to the formation of germ layers during embryonic development.
