Study Notes
5 Characteristics of Life
- Organization, Growth and Development, Reproduction, Response to Stimulus, and Adaptations and Evolution define life forms.
Organization
- Cells: Basic structural and functional units in living organisms (e.g., skin cells, bone cells).
- Tissues: Groups of similar cells working together (e.g., nerve and muscle tissues).
- Organs: Collections of tissues that perform specific functions (e.g., heart, roots, and stems).
- Organ Systems: Multiple organs collaborating for specific tasks (e.g., Muscular System, Cardiovascular System, Skeletal System).
- Organism: An individual form of life capable of reacting and reproducing (e.g., bacteria, humans).
Growth and Development
- Growth refers to the increase in living material and complexity.
- Single-celled organisms grow slower than multicellular ones due to less complexity.
Reproduction
- Sexual Reproduction: Involves two organisms creating a new organism.
- Asexual Reproduction: A single organism reproduces independently without mating.
- Essential for species continuation, enabling the production of offspring of the same species.
Response to Stimulus
- Irritability: Ability to respond to environmental changes, which can vary in speed.
- Stimuli can be light, temperature, odor, sound, gravity, heat, water, and pressure.
Adaptations and Evolution
- Adaptation: Inherited characteristics enhancing survival and reproduction potential in specific environments.
- Evolution involves genetic modifications in a species over extended timespans (e.g., black beetles' coloration versus white beetles').
- Example: Wolves with thick fur are better suited for colder climates compared to those with thin fur.
