What criteria do we use to decide whether something is alive?

Answer:

Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye.  Therefore, the presence of life processes is a fundamental criterion that can be used to decide whether something is alive or not.

Evidence which can ensure something is alive or not

  • Shape and Dimension
  • Reproduction
  • Growth
  • Cellular structure
  • Metabolism
  • Movements
  • Self-regulations
  • Variation
  • Co- ordination
  • Definite life cycle
  • Death

Example – Movements are fast in most animals but motions in plants are generally slow.
