#### Defining Life
**Life** can be defined as the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death. Life is a characteristic that distinguishes physical entities that have biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased, or because they never had such functions and are classified as inanimate. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria.
Life shows definitive characteristics that include homeostasis, organization, metabolism, growth, adaptation, response to stimuli, and reproduction. Living organisms undergo metabolism, maintain homeostasis, possess a capacity to grow, respond to stimuli, reproduce and, through natural selection, adapt their species to their environment in subsequent generations. More complex living organisms can communicate through various means.
#### Properties of Life
Some key properties of life include:
– **Homeostasis** – The ability of an organism to regulate its internal environment to maintain a stable and constant condition. This involves processes such as temperature regulation, metabolism, and nutrient transport.
– **Organization** – The ability of organisms to regulate and coordinate complex chemical reactions between molecules to form organized structures like cells, tissues, organs and organ systems.
– **Metabolism** – The sum of an organism’s chemical and physical processes that allow it to grow, reproduce, and maintain organization. Metabolism involves the intake of nutrients and energy from the environment and their conversion into cellular building blocks and energy through anabolic and catabolic reactions.
– **Growth** – The ability of organisms to increase in size through cellular growth and cell division or asexual reproduction.
– **Adaptation** – The ability of organisms to adapt to their environment through genetic changes and modifications in anatomy, physiology and behavior across generations. Adaptations increase the chances of survival.
– **Response to stimuli** – The ability to detect and respond to stimuli from the internal and external environment. This allows organisms to move, hunt, avoid predators and adapt to environmental changes.
– **Reproduction** – The ability to produce new individuals through asexual or sexual reproduction, allowing organisms to multiply and pass on genetic information between generations.
I hope this overview of life and its key properties helps explain the concept. Please let me know if you need any clarification or have additional questions.
