- Biology
- Science of life
- Six Themes of Biology
- Cell structure & function, Stability & homeostasis, Reproduction & inheritance, Evolution, Organisms' interdependence, Matter, energy, & organization
- Cells
- Small, highly organized, make up living things, containing specialized structures to carry out life processes
- Differentiation
- Process when cells of multicellular organism become different for special roles
- Homeostasis
- Stable level of internal conditions found in all living things
- Reproduction
- Process of producing offspring, during which hereditary information is transmitted
- DNA
- (Deoxyribonucleic acid) Large molecules in form of a membrane/loop that holds hereditary information
- Gene
- Short segment of DNA that contains instructions for development of a single trait of an organism
- Sexual Reproduction
- Hereditary information from 2 parts of a single organism/ 2 organisms of same species is combined
- Asexual Reproduction
- Hereditary information isn't combined from different organisms
- Evolve
- Changing of organisms over time
- Evolution
- Changes that organisms have made from their first existence to now
- Natural Selection
- Process considered the most important driving force in evolution; "Survival of the Fittest"
- Ecology
- Branch of biology studying organisms' interactions with one another & environment
- Ecosystems
- Environmental communities
- Photosynthesis
- Process by which plants & some unicellular organisms capture the sun's energy & change it to usable energy
- Autotrophs
- Organisms that obtain energy by making their own food; Use Water/Carbon Dioxide/Chemical processes for energy
- Heterotrophs
- Organisms that take in food for energy needs; Need to consume autotrophs/ heterotrophs for energy
- Levels of Organization
- Atom, Molecule, Organelle, Cell, Tissue, Organs, Organ System, Organism, Population, Community, Ecosystem, Biome, Biosphere
- Atom
- Smallest part of an element with properties of that element
- Molecule
- Two/more atoms together
- Organelle
- Part of a cell that carries out a specific job
- Cell
- Smallest part of a living thing
- Tissue
- Group of cells with a special job
- Organs
- Groups of tissues with a special job
- Organ System
- Groups of organs working together
- Organism
- Living thing
- Population
- Groups of organisms
- Community
- All populations living in an area
- Ecosystem
- Living & nonliving things in an area
- Biome
- Region on Earth with characteristic climate
- Biosphere
- Where living things are found (Earth)
- 6 Characteristics of Life
- Homeostasis, Energy Use, Reproduction, Cells, Organization, Growth & Development
- Observation
- Conclusion made using the senses
- Inference
- A logical conclusion based on observations & previous knowledge
