Study Notes
Characteristics of Life
- Definitions of life vary among biologists and scientists, illustrating its complexity.
- Commonly accepted characteristics that define life include several key features.
Metabolism
- Involves chemical processes that convert nutrients into energy and materials for growth.
- Essential for maintaining cellular functions and overall organismal activities.
Organization
- Living organisms exhibit a structured arrangement, from cells to complex systems.
- Levels of organization include cells, tissues, organs, and systems, highlighting complexity.
Homeostasis
- Refers to the ability to maintain stable internal conditions despite external changes.
- Vital for processes such as temperature regulation and pH balance.
Irritability
- The capacity of an organism to respond to stimuli in its environment.
- Critical for survival, as it helps organisms adapt and react to changes.
Growth
- Living organisms undergo a process of development and increase in size.
- Growth involves cell division and differentiation, leading to complexity.
Reproduction
- The ability to produce new individuals, ensuring the continuation of a species.
- Can occur through sexual or asexual methods, contributing to genetic diversity.
Evolution
- The process through which populations change over time, adapting to their environments.
- Driven by mechanisms like natural selection, influencing the diversity of life.
