Biotic Factors – All of the living factors within an environment.
Abiotic Factors – All of the nonliving factors within an environment (soil, temperature,
rocks, weather).
Organism – A single, living thing able to grow and to reproduce.
Population – A group of organisms of the same species located within the same
geographical area.
Community – All of the populations of different species in a particular area.
Ecosystem – A system consisting of all of the interactions that occur between the abiotic
and biotic factors within an environment.
Cell – The smallest unit of an organism; it is enclosed by a membrane and performs life
functions.
Nucleus – A structure found in eukaryotic cells that contains DNA and is responsible for
controlling the activities of the cell.
Prokaryotic Cell – A cell lacking a nucleus or any other membrane-enclosed organelle.
Eukaryotic Cell – A cell containing a membrane-enclosed nucleus and organelles.
Unicellular – consisting of a single cell
Multi-Cellular – consisting of more than one cell
Autotroph – An organism that is able to make its own food.
Heterotroph – An organism that cannot make its own food.
Asexual Reproduction - A method of reproduction that requires only one parent.
Sexual Reproduction - A method of reproduction that requires both a male and a female
parent.
Domain – The primary or highest-ranking classification of organisms, which includes
three groups: Archaea, Bacteria, and Eukarya.
Kingdom - A taxonomic rank below domain that is composed of smaller groups:
Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.

Prokaryotic cell is simple, relatively small in size, and does not have a nucleus.
Eukaryotic cells are complex, relatively larger, and contain a nucleus and other
membrane bound organelles.
