Study Notes
Characteristics of Life
- Life is defined by a specific structure; organization ranges from molecules to biospheres.
- Hierarchical order: Molecule → Organelles → Cell → Tissue → Organ → Individual → Population → Ecosystem → Biosphere.
- Living organisms, whether unicellular or multicellular, share similar metabolic functions and cellular structures.
- Unique chemical compounds, such as lipids and DNA, are exclusive to living organisms.
- Genes store essential information for cellular operations, with replication occurring during cell division.
- Reproduction involves the transfer of genetic information to successive generations.
- Organisms experience growth and development as part of a life cycle.
- Metabolism involves converting matter into energy and eliminating waste.
- Organisms demonstrate the ability to react to environmental changes and exhibit adaptive behaviors.
- Homeostasis refers to the internal regulation of physical and chemical states to maintain equilibrium.
