Study Notes
Differentiating the Living from the Non-Living
- Living beings exhibit observable activities, such as movement, breathing, or vocalization.
- Even when asleep, organisms like dogs, cows, or humans can be identified as alive based on their potential to breathe.
- Green plants are often perceived as alive; however, color does not always indicate life.
Characteristics of Life
- Growth is a common criterion for determining life; yet, organisms can be alive without visible growth.
- Some life forms, such as dormant plants or certain animals, may not display evident movement but are still alive.
- Molecular movement, although invisible to the naked eye, plays a crucial role in sustaining life.
Molecular Movement and Life
- Biologists affirm that molecular movement is essential for life processes.
- Viruses lack internal molecular movement until they invade a host cell, contributing to the debate over their classification as living entities.
Importance of Molecular Movements
- Living organisms are structurally organized into tissues, cells, and smaller components.
- Environmental factors can lead to the decay of this organizational structure; if it deteriorates, the organism will die.
- Maintenance of order within living systems requires constant molecular movement to repair and support their structures.
Maintenance Processes in Living Organisms
- Organisms actively manage their internal environment to maintain their organized state, essential for survival and functionality.
- Understanding these processes offers insight into what constitutes life and the necessary conditions for sustaining it.
