Yes, because some organisms, like plants, may exhibit minimal or imperceptible movement yet remain alive. Additionally, certain animals may exhibit vital functions such as respiration without overt movement.
Are there limitations to using visible movement as the sole defining characteristic of life?

Yes, relying on visible movement as the sole defining characteristic of life has limitations. Some organisms, like plants, fungi, and certain microorganisms, may exhibit minimal or no visible movement despite being alive. Additionally, certain stages of an organism’s life cycle or periods of dormancy may lack observable motion. Moreover, technological constraints may limit our ability to detect microscopic movements. Life encompasses a broader range of characteristics, including cellular organization, metabolism, growth, reproduction, and adaptation. Considering these factors collectively provides a more comprehensive understanding of life, avoiding oversimplification based solely on visible movement.
