1. Organization: Organisms are highly organized, with cells as the basic unit of life. They exhibit different levels of organization, from cells to tissues, organs, and organ systems.

2. Metabolism: Organisms carry out a wide range of chemical reactions to sustain life. These include processes like respiration, photosynthesis, and nutrient cycling.

3. Growth and Development: Organisms increase in size and complexity over time. This can involve cell division, differentiation, and specialization.

4. Responsiveness: Organisms can detect and respond to stimuli in their environment. This includes things like changes in temperature, light, or the presence of food.

5. Reproduction: Organisms can create new individuals of their own kind. This can be through sexual or asexual means.

These traits are what define life and set organisms apart from non-living things.
