Reason:: Plants retain the capacity of continuous growth throughout their life.
Answer & explanation
Correct answer: option 1
Plants are built in a modular fashion where the structure is never complete because their tips are open-ended where growth is continuously taking place. Thus, growth in plants is unlimited, indeterminate i.e. indefinite.
Plant growth is unique because plants retain the capacity for unlimited growth throughout their life. This ability of the plants is due to the presence of meristems that have the capacity to divide and self-perpetuate at certain locations in their body.
