What is a Living Thing? – Meaning and Definition
Definition:
A living thing is any organism that exhibits the characteristics of life, such as growth, reproduction, response to stimuli, metabolism, and adaptation to the environment.
Characteristics of Living Things:
- Growth and Development: Increase in size and complexity over time.
Example: A seed grows into a plant. - Reproduction: The ability to produce offspring.
Example: Animals give birth, and plants produce seeds. - Metabolism: Chemical reactions that provide energy for growth, repair, and maintenance.
Example: Digestion in humans. - Response to Stimuli: Reaction to environmental changes.
Example: A plant bending towards light. - Adaptation: Ability to adjust to the environment for survival.
Example: Polar bears have thick fur to survive in cold regions. - Cellular Organization: Composed of one or more cells, which are the basic units of life.
Example: Humans are multicellular, while bacteria are unicellular. - Homeostasis: Maintaining internal balance despite external changes.
Example: Humans maintain body temperature.
Examples of Living Things:
- Animals: Humans, lions, birds, insects
- Plants: Trees, flowers, grasses
- Microorganisms: Bacteria, fungi, protozoa
Difference Between Living and Non-Living Things:
| Characteristics | Living Things | Non-Living Things |
|---|---|---|
| Growth | Yes | No |
| Reproduction | Yes | No |
| Metabolism | Yes | No |
| Response to Stimuli | Yes | No |
| Cellular Organization | Yes (Cells) | No (No cells) |
| Adaptation | Yes | No |
| Movement | Some can move | No independent movement |
Importance of Living Things:
- Ecosystem Balance: Maintain ecological balance.
- Oxygen Production: Plants produce oxygen, essential for survival.
- Food Chain: Serve as producers, consumers, and decomposers.
- Biodiversity: Contribute to the diversity of life.
