Besides movement, other criteria for identifying life include cellular organization, metabolism, homeostasis, reproduction, and adaptation to the environment. These criteria collectively provide a more comprehensive understanding of what constitutes life.

Determining if something is alive involves considering multiple criteria. Cellular organization is fundamental, as living entities are composed of cells. Metabolism, the ability to acquire and utilize energy, is crucial. Growth involves an increase in size or complexity. Reproduction ensures the continuation of the species. Response to stimuli demonstrates interaction with the environment. Homeostasis maintains internal stability. Adaptation allows organisms to evolve and survive changing conditions. While visible movement can be a factor, it’s not universal. Combining these criteria provides a holistic approach to defining life, accommodating the diversity of living entities, from microscopic bacteria to complex multicellular organisms.
