Function The job that a cell, tissue, organ, or organ system does.
Structure The arrangement of a cell, tissue, organ, or organ system, including the shape and the material of which it is made.
Cell Membrane The protective layer that covers the cell’s surface, acts as a barrier, and controls materials going into and out of the cell.
Nucleus A membrane-enclosed organelle found in eukaryotic cells that contains most of the cell's genetic material and controls the activities of the cell.
Organelles Cellular structures that perform specific functions within the eukaryotic cell.
Unicellular Organism A living thing that consists of only one cell.
Multicellular Organism A living thing that consists of more than one cell.
Specialization Each cell in a multicellular organism having a specific job.
Tissue A group of cells that work together to perform a specific job.

Organ System A group of organs that work together to perform a specific function.
Organism Anything that can perform life processes by itself.
Cell Division The process by which a parent cell divides into two or more daughter cells.
Differentiation The process by which their structure and functions become specialized to perform specific jobs.
Stem Cells Undifferentiated cells that can differentiate into specialized calls and can then undergo cell division to form tissues and possibly organs.

Recessive Trait Traits that disappear and are not observed in the offspring when parents that have different traits are bred.
Allele Different forms of genes.
Punnett Square A diagram used to figure out what type of offspring will be produced when two parents are bred by sexual reproduction.
Cytoplasm The gel-like substance enclosed within the cell membrane.
Prokaryotic Cell A simple cell that does not have a nucleus and has few membrane-enclosed organelles.
Eukaryotic Cell A more complex cell that contains a nucleus and more membrane-enclosed organelles.
