Apoptosis, or programmed cell death, plays several crucial roles in animal development. Which of the following is an accurate function of apoptosis?

  • option_a: Increasing the overall number of cells in an embryo
  • option_b: Formation of new germ layers during gastrulation
  • option_c: Shaping organs and tissues by removing unwanted cells
  • option_d: Facilitating cell migration through convergent extension

Explanation

The text mentions apoptosis as 'programmed cell death' and in the context of C. elegans, it states 'programmed cell death contributes to animal development.' In broader biological contexts, apoptosis is well-known for its role in sculpting tissues e.g., digit formation and removing defective or unnecessary cells during development.
