The formation of the neural plate is given as an example of 'induction'. Based on the definition provided, which scenario best illustrates this developmental process?

  • A: Mesodermal cells secrete signaling molecules that cause the overlying ectoderm to thicken and form the neural plate.
  • B: Cells differentiate into various types independently without interaction from surrounding tissues.
  • C: A group of cells undergoes programmed cell death to sculpt a developing structure.
  • D: Cells migrate from one location to another to form a new tissue structure.

Explanation

The text defines induction as 'a process in which a group of cells or tissues influences the development of another group through close-range interactions.' Option A directly illustrates this definition using the example provided in the text regarding notochord inducing the neural plate.
