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.
