Levels of Organization. Growth & Differentiation

Vocabulary flashcards covering levels of organization, necessary life functions, and growth & differentiation from Page 1 notes.

Cell

Basic structural & functional unit of a living organism.

Tissue

Group of similar cells performing a specific function.

Organ

A structure composed of two or more tissue types, working together to perform specific functions.

Organ System

Growth

A necessary life function of an organism.

Differentiation

Process in which unspecialized cells become specialized to perform specific functions.

Growth & Differentiation

Growth increases size/quantity of structural units, while differentiation makes units more specialized as you move from cells to tissues to organs to organ systems.

Levels of Organization

A hierarchical arrangement from cells to tissues to organs to organ systems to organism.
