Study Notes
Unifying Themes in the Study of Life
- Basic ideas that apply to all organisms
- Connects many things in the exploration of life
Cell Theory
- All living organisms are composed of one or more cells
- The cell is the fundamental building block of life
Evolution
- Process of change in heritable characteristics of populations over successive generations
- Explains the diversity of life and how species adapt to their environments through natural selection
Genetics
- Study of heredity and the variation of inherited characteristics
- Explains how traits are passed from one generation to the next
Homeostasis
- An organism's ability to maintain a stable internal environment despite changes in external conditions
- Crucial for survival
Energy Flow and Matter Cycling
- Energy flows through ecosystems, and matter is recycled
- Energy is transformed through various processes (photosynthesis, cellular respiration)
Interdependence of Organisms
- Organisms interact with each other and their environment to form ecosystems
Structure and Function
- The structure of biological entities (cells, tissues, organs, organisms) is closely related to their function
Adaptation
- Traits that enhance an organism's ability to survive and reproduce in its environment
- Development and reproduction are crucial for species continuation
- Biological organization ranges from molecules to ecosystems, each level building on the previous
Ancient and Classical Theories (Before 1600s)
- Early civilizations believed in supernatural forces
- Aristotle's concept of spontaneous generation dominated
- Empedocles proposed life from four elements: earth, air, fire, water
Discovery of Microorganisms (1600s)
- Robert Hooke described cells observed in cork
- Antonie van Leeuwenhoek discovered microorganisms, expanding the understanding of life's diversity
Challenging Spontaneous Generation (1700s-1800s)
- John Needham supported spontaneous generation
- Lazzaro Spallanzani disputed Needham's findings, demonstrating that sterilized broth doesn't generate life
Cell Theory and Germ Theory (1800s)
- Matthias Schleiden and Theodor Schwann developed cell theory
- Rudolf Virchow added to cell theory, stating all cells come from pre-existing cells
- Pasteur and Koch developed germ theory, establishing the link between microorganisms and disease
Darwin's Theory of Evolution (1800s)
- Charles Darwin introduced the theory of natural selection, reshaping the understanding of life's diversity and interconnectedness
- Gregor Mendel's work on inheritance laid the foundation for modern genetics
Emergence of Molecular Biology (1900s)
- Avery, MacLeod, and McCarty identified DNA as the heredity substance
- Watson and Crick discovered the DNA double helix structure
- Understanding how DNA dictates protein synthesis deeper understood
Astrobiology and Search for Extra-Terrestrial Life (Late 1900s - Present)
- Advances in space exploration, along with extremophile discoveries
- Debate over the potential for life beyond Earth
- Kepler mission's identification of exoplanets increased the possibility of habitable worlds
Biochemistry and Synthetic Biology (21st Century)
- Completion of the Human Genome Project
- Craig Venter created the first synthetic cell
- CRISPR gene-editing tool for DNA manipulation
Current and Future Concepts
- Theories of life are influenced by system biology
- Scientific debates on the definition of life, particularly concerning artificial intelligence, synthetic biology, and astrobiology
- New discoveries challenge traditional biological definitions
Microscopy Parts and Functions
- Tools for viewing small organisms or objects
- Magnification: how much larger an object appears
- Resolution: ability to distinguish between points
- Compound Microscope: uses visible light, glass lenses to magnify images
Major Microscope Parts
- Magnifying Parts (eyepiece/ocular lens & objective lenses)
- Illuminating Parts (mirror, iris diaphragm, stage condenser)
- Mechanical Parts (body tube, revolving nosepiece, adjusting knobs, stage, stage clips)
Asexual Reproduction
- Single parent produces offspring genetically identical to the parent
- Adaptation for sessile organisms, rapid population growth
Budding
- Small part of the parent separates, grows, develops into a new individual
Fragmentation & Regeneration
- Parent body breaks into fragments, which regenerate into fully developed organisms
- Flatworms, annelids show this ability
Parthenogenesis
- Development of unfertilized eggs into an adult organism
- Common in some insects, crustaceans, etc
Sexual Reproduction
- Involves the fusion of egg and sperm
- Animals can be dioecious or monoecious ("hermaphroditic")
Fertilization
- Union of sperm and egg
- Can be external (female releases eggs, male fertilizes) or internal (male delivers sperm)
- Three ways offspring is produced following internal fertilization (oviparity, ovoviviparity, viviparity)
Interactions
- Food Chain: Linear sequence showing energy and nutrient flow
- Food Web: All food chains in an ecosystem
- Ecosystem: Living (biotic) and nonliving (abiotic) components in an area
- Predator-Prey: Predatory species consume prey species
- Competition: Struggle over limited resources
- Cooperation: Organisms working together for mutual benefit
- Symbiosis: Two species living together in a close relationship (mutualism, commensalism, parasitism)
- Biotic Potential: Ability to reproduce under ideal conditions
- Environmental Resistance: Limiting factors (biotic and abiotic) on population growth
Social Relationships in Middle and Late Adolescence
- Socialization: Acquiring societal values, habits, and attitudes
- Social Relationships: Adolescent relationships with wider groups (schoolmates and peer groups)
- Social Influence: Changes in beliefs, attitudes, and behaviors exerted by others
Types of Social Influence
- Compliance: Agreeing to requests or requirements without necessarily believing in them
- Identification: Influenced by those they like
- Conformity: Changing behaviors to fit in with a group
- Conversion: Wholeheartedly changing beliefs and practices
- Obedience: Following someone's instructions (especially an authority figure)
- Persuasion: Influencing another person's beliefs, actions, or attitudes
Leadership Theories
- Trait: Leaders possess specific personality traits
- Behavioral: Leadership is learned behavior
- Participative: Involves others in decision-making
- Situational: Leadership adapts to the situation
- Transactional: Negotiation-based leadership with rewards and punishments
- Transformational: Visionary leadership motivating others
Leadership Styles
- Autocratic: Centralized power, control, and rewards
- Democratic: Participative decision-making and input from team members
- Laissez-Faire: Hands-off approach
Family
- Group of people related by blood, marriage, or adoption
- Types of families: Nuclear, Extended, Blended/Step, Adoptive, Single-parent
Parenting Styles
- Authoritative: Supportive, nurturing, and sets clear limits
- Permissive: Loving and accepting without strict guidelines
- Authoritarian: Control-focused, and undemonstrative
- Uninvolved: Neglectful and unsupportive
Career and Life Goals
- Career: a role enabling you to apply skills and knowledge
- Career Development: continually enhancing abilities to achieve goals in the work environment
