Grade 8 Development and Reproduction
Which of these choices describes what happens during budding?
  1. An egg cell is fertilized by a sperm cell, and the resulting cell develops into an offspring that is not identical to either parent.
  2. A new plant develops from a modified stem or root taken from a parent plant to form a genetically identical offspring.
  3. An organism produces a single, specialized cell that develops into a new, multicellular organism with the same genetic information as the parent.
  4. A new organism begins as a growth on the outside surface of the parent organism, and it eventually separates from the parent, creating a genetically identical individual.
