Study Notes

Sensitivity or Response to Stimuli

Organisms detect changes in their environment, triggering reactions known as responses.
External stimuli include light, temperature, sound, touch, and chemicals.
Ability to respond is vital for survival and adaptation to varying conditions.

Reproduction

Organisms have mechanisms to reproduce, passing genetic traits to their offspring.
Reproduction is essential for the continuity of life and ensures the survival of species.
Can occur through various methods including sexual and asexual reproduction.

Growth and Development

Organisms undergo growth, which is an increase in size or mass.
Development refers to structural and functional changes organisms experience over time.
Essential adaptations occur through development, enabling organisms to thrive in diverse habitats.

Homeostasis

Refers to the ability of organisms to maintain a stable internal environment despite external changes.
Crucial for regulating physiological functions necessary for survival.
Internal conditions must remain within narrow limits, allowing organisms to adapt to varying environments.

Energy Processing

Organisms require energy to conduct biological functions and activities.
Energy processing supports metabolic activities necessary for growth and reproduction.
Different organisms utilize various sources of energy, including photosynthesis and consumption of food.
