Study Notes
Characteristics of Life
-
Sensitivity or Response to Stimuli: Organisms react to environmental changes, crucial for survival and adaptation. This includes responses to light, temperature, sound, touch, and chemicals.
-
Reproduction: Organisms can reproduce, ensuring genetic transfer to offspring, which is vital for species continuity and survival.
-
Growth and Development: Involves both increase in size/mass (growth) and structural/function changes (development), enabling adaptation to various environments.
-
Homeostasis: The ability to maintain internal stability despite external changes is essential for survival, regulating crucial internal functions within narrow limits.
-
Energy Processing: Organisms utilize energy for physiological activities, essential for supporting biological functions.
Branches of Biology
- Helminthology (⚪️): Study of worms.
- Ornithology (🐦): Study of birds.
- Arachnology (❤️): Study of arachnids (eight-legged organisms).
- Biochemistry (🧬): Examines chemical reactions in living organisms.
- Organology (⚪️): Focuses on organs within organisms.
- Physiology (➡️): Studies functions and processes of organs.
- Evolution (➡️): Focus on the change in species over time.
- Systematics (⬅️): Concerned with naming and classifying organisms.
- Natural History (😮): Study of living things and their environments.
- Phycology (⬜️): Study of algae.
- Dendrology (❌): Study of trees.
- Malacology (🌟): Study of mollusks.
- Ichthyology (🔼): Study of fishes.
- Mammalogy (💎): Study of mammals.
- Microbiology (🔽): Study of microorganisms.
Levels of Biological Organization
-
Chemical: Atoms and molecules are the basic units of life (e.g., carbohydrates, proteins).
-
Cell: The smallest functional unit of life, exemplified by skin cells.
-
Organ: Composed of tissue groups performing specialized functions (e.g., lungs and heart).
Sterilization vs Disinfection
-
Sterilization: A process that completely eradicates all life forms, including bacteria and viruses; important in medical settings (e.g., surgical tools, food processing for canned goods).
-
Disinfection: Reduces harmful microorganisms significantly but does not eliminate all; used in cleaning surfaces and sanitizing food.
