The correct answer is:
Cells rush to the damaged area, proliferate through mitosis, and work to repair the injury.
When a complex organism is injured, cells respond by rushing to the damaged area. They do this through a process called chemotaxis, which is guided by chemical signals released by the injured tissues. Once cells reach the site of injury, they start to proliferate, or reproduce, through mitosis. This means that they divide to create new cells that can assist in the repair process. By proliferating, the cells increase in number and can work together to restore the injured area. These cells may differentiate into various cell types needed for repair, such as fibroblasts for collagen production or immune cells to defend against infection. Overall, the cellular response to injury involves migration, proliferation, and specialized functions to repair the damaged tissue.
