Study Notes
Definition and Scope of Zoology
- Zoology is a branch of biology focused on the study of animals.
- It examines family relationships among animals and their classification.
Key Concepts in Science
- Science derives from the Latin "scientia," meaning knowledge; it studies the natural world through experiments and observations.
- Fields of Science:
- Social Science: Focuses on human behavior and societies.
- Natural Science: Concerned with natural phenomena, including biology.
- Abstract Science: Involves the study of mathematics and statistics.
Biology and Its Branches
- Biology encompasses the study of living organisms and includes several subfields:
- Zoology: Study of animals.
- Botany: Study of plants (also known as Phytology).
- Microbiology: Study of microorganisms.
Historical Figures in Zoology
- Aristotle: Known as the Father of Zoology.
- Theophrastus: Regarded as the Father of Botany.
- Louis Pasteur: Recognized as the Father of Microbiology.
Branches of Zoology
- Major branches include:
- Herpetology: Study of reptiles and amphibians.
- Entomology: Study of insects.
- Ornithology: Study of birds.
- Ecology: Study of relationships between organisms and their environment.
- Physiology: Study of functions and processes in organisms.
- Morphology: Study of the structure of organisms.
- Taxonomy: Classification of organisms.
Molecular Biology Basics
- Living organisms are composed of macromolecules:
- Nucleic Acids: DNA and RNA direct genetic information.
- Proteins: Made from amino acids, perform various functions such as structure and transport.
- Carbohydrates: Serve as main energy sources and structural components in cells.
- Lipids: Includes triglycerides and phospholipids, essential for energy storage and cellular membranes.
Cellular Structures and Functions
- Cells are the basic unit of life, consisting primarily of carbon, hydrogen, oxygen, and nitrogen.
- Proteins play critical roles in cellular functions, including:
- Hemoglobin: Oxygen transport.
- Insulin: Regulates blood sugar.
- Collagen: Provides structure to tissues.
Hierarchical Organization of Living Systems
- Biological hierarchy progresses from molecules to cells, tissues, organisms, populations, and species.
- Living systems reproduce through genetic information contained in DNA.
Metabolism and Energy Management
- Metabolism consists of catabolic (breaking down) and anabolic (building up) reactions.
- Organisms acquire nutrients and energy from the environment, essential for growth and activity.
Ecology and Environment Interaction
- Ecology studies interactions between organisms and their environments.
- Organisms exhibit responses to environmental stimuli, showcasing controlled movements.
Characteristics of Living Organisms
- All living organisms exhibit key characteristics:
- Reproduction: Capacity to produce offspring.
- Growth: Increase in size or number of cells.
- Response to Stimuli: Reaction to environmental changes.
- Development: Progressive changes throughout life cycles.
Classification of Organisms
- Multicellular: Composed of multiple cells.
- Eukaryotes: Cells with membrane-bound nuclei.
- Heterotrophs: Organisms that depend on external food sources for energy.
