Study Notes
Introduction to Biology
- Biology is the scientific study of life and living organisms.
- It encompasses a wide range of subjects, including the structure, function, growth, origin, evolution, and distribution of living things.
- Key areas of study include cell biology, genetics, ecology, and evolutionary biology.
- The scientific method is essential for biological research, involving experiments to test hypotheses and gather data.
Characteristics of Living Organisms
- Organisms exhibit specific characteristics defining life:
- Cellular organization: All living organisms are composed of cells.
- Metabolism: Chemical reactions (metabolism) are used to acquire and utilize energy.
- Reproduction: Organisms produce offspring, essential for species continuation.
- Growth and development: Organisms increase in size and complexity.
- Response to stimuli: Organisms react to internal and external environmental changes.
- Homeostasis: Living organisms maintain a stable internal environment.
- Adaptation: Organisms evolve to better suit their environments.
Levels of Biological Organization
- From molecular to biosphere:
- Atoms and molecules form the basis of living matter.
- Molecules combine to form macromolecules, composing cellular structures.
- Cells are the basic units of life.
- Tissues: Similar cells working together.
- Organs: Various tissues forming a functional unit.
- Organ Systems: Groups of organs working for a specific function.
- Organisms: Individual living beings.
- Populations: Organisms of the same species in an area.
- Communities: Interactions among different populations.
- Ecosystems: Interactions between living organisms and the physical environment.
- Biosphere: All Earth's ecosystems.
Branches of Biology
- Major biological disciplines:
- Botany: The study of plants.
- Zoology: The study of animals.
- Microbiology: The study of microorganisms.
- Ecology: The study of organism-environment interactions.
- Genetics: The study of heredity and variation.
- Evolution: The study of population changes over time.
- Cell biology: The study of cell structure and function.
- Physiology: The study of organism functions.
- Biochemistry: The study of chemical processes in living organisms.
Scientific Method in Biology
- The scientific method is a systematic approach to understanding the natural world.
- Observation: Identifying a phenomenon or pattern.
- Hypothesis: A testable explanation.
- Prediction: Specific outcome based on the hypothesis.
- Experiment: Controlled test of the hypothesis.
- Analysis and Conclusion: Evaluating data and interpreting results.
- Communication: Sharing findings with the scientific community.
