Plastids · Botany

What happens to the number of plastids during cell division?

  1. They are synthesized from scratch in the nucleus.
  2. They are imported from neighboring cells.
  3. They disappear and reappear after division.
  4. They replicate through binary-like fission.
Show answer and explanation

Correct answer: They replicate through binary-like fission.

Plastids are semi-autonomous organelles that replicate through division. This fission process involves a contractile ring and ensures that each daughter cell receives a population of plastids.
