A multicellular organism grows by _________.
Cell division
Correct Answer: Option 4 – Cell division
How multicellular organisms grow:
Multicellular organisms (like humans, animals, and plants) grow mainly through mitosis, a type of cell division.
What happens in cell division:
One parent cell divides to form two identical daughter cells.
This increases the total number of cells in the body, leading to growth, development, and tissue repair.
Why other options are incorrect:
Cell addition: not a biological process; it is just a result of cell division.
Cell explosion: would destroy cells, not support growth.
Cell implosion: also destroys cells and is not related to growth.
