Ques: Answer the following question given this paragraph: called growth factors signal some cells at the edge of the ectoderm to become epidermis cells. The remaining cells in the center form the neural plate. If the signaling by growth factors were disrupted, then the entire ectoderm would differentiate into neural tissue. The neural plate undergoes a series of cell movements where it rolls up and forms a tube called the neural tube, as illustrated in Figure 43.28. In further development, the neural tube will give rise to the brain and the spinal cord. Q: The neural plate undergoes a series of cell movements where it rolls up and forms a tube called what? Choices: - cell tube - occular tube - peripheral tube - neural tube A:
Ans:
neural tube
