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
|
