Which of the following statements best describes why visible movement alone cannot define whether a plant is alive?
Plants may be alive even without visible growth or movement.
Movement is commonly associated with life because animals visibly walk, run or crawl, but this is not a universal test for identifying living things.
Plants are alive even though they do not show obvious locomotion — they carry out life processes like respiration, photosynthesis, growth and reproduction, often through slow or internal movements that are not easily visible.
So the absence of visible movement does not mean a plant is not alive; it simply moves differently, for example through growth of roots and shoots or the opening of flowers.
Hence, the correct answer is that plants may be alive even without visible growth or movement.
