Study Notes
General Properties of Living Things
- Living systems are characterized by unique and complex molecular organization, distinguishing them from non-living systems.
Chemical Uniqueness
- Macromolecules are the large, complex molecules that comprise living systems.
- The four primary macromolecules in living organisms are:
- Lipids
- Carbohydrates
- Proteins
- Nucleic Acids
Complexity and Hierarchical Organization
- Living organisms exhibit a structured hierarchy of complexity, arranged in levels such as:
- Macromolecules
- Cells
- Organisms
- Populations
- Species
Reproduction
- An essential property of living systems is their ability to reproduce, ensuring the continuation of their species.
Possession of a Genetic Program
- Living organisms possess a genetic program that guarantees fidelity in inheritance.
- DNA, composed of long chains of nucleotides, serves as the primary storage for genetic information.
- Each nucleotide consists of a sugar, a phosphate group, and a nitrogen base.
Metabolism
- Metabolism encompasses processes such as:
- Digestion
- Energy recovery (respiration)
- Synthesis of vital molecules and structures.
- Physiology is the study of metabolic functions across various levels, from biochemical processes to overall organismal function.
Development
- All organisms undergo a life cycle that includes distinct stages of development.
- Metamorphosis refers to significant morphological changes that occur during an organism's development.
Environmental Interaction
- Ecology is the study of how organisms interact with their environments.
- Irritability, a fundamental characteristic of all living beings, refers to their ability to respond to environmental stimuli.
Movement
- Living systems demonstrate precise and controlled movements generated internally, showcasing their active nature.
