Community
an assemblage of all the populations of organisms living close enough together for potential interactions
Population
a group of individuals belonging to one species and living in the same geographic area
Ecosystem
all of the organisms in a given area, along with the non-living (abiotic) factors with which they interact; a biological community, and its physical environment
Molecule
two or more atoms held together by covalent bonds
Organelle
a membrane enclosed structure with a specialized function within a cell
Cell
a basic unit of living matter separated from its environment by a plasma membrane; the fundamental structural unit of life
Tissue
an integrated group of cells with a common function, structure, or both
Organ
a specialized structure composed of several different types of tissue, that together perform specific functions
Organ System
a group of organs that work together in performing vital body functions
Organism
an individual thing such as bacterium, fungus, protist, plant, or animal
Emergent Properties
new properties that arise with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases
Prokaryotic Cell
a type of cell lacking a membrane -enclosed nucleus and other membrane-enclosed organelles; found only in the domains Bacteria and Archaea
Eukaryotic Cell
a type of cell that has a membrane-enclosed nucleus and membrane enclosed organelles. all organisms except bacteria and archaea are composed of eukaryotic cells
Systems Biology
an approach to studying biology that aims to model the dynamic behavior of whole biological systems based on a study of the interactions among the systems parts.
