Biology Chapter 1: Exploring Life

Biosphere = All of the environments on Earth that support life Ecosystem = All the organisms living in a particular area and the physical components with which the organisms interact Organism = An individual living thing Community = The entire array of organisms living in a particular ecosystem

Organ system = Several organs that cooperate in a specific function Organ = A structure that is composed of tissues Tissue = A group of similar cells that perform a specific function Organelle = A membrane-enclosed structure that performs a specific function within a cell

Reproduction = The process of producing offspring Growth and development = The process of increasing in size and complexity Energy processing = The process of generating energy for the organism Regulation = The process of maintaining homeostasis

<p>Molecule = Smallest unit of biological organization Cell = The fundamental unit of life Organism = An individual living thing Biosphere = Largest unit of biological organization</p> Signup and view all the answers

<p>Emergent properties = New properties that arise from the arrangement and interactions among component parts Evolutionary adaptation = The process of adapting to the environment over many generations Order = The organization of components in a specific pattern Response to the environment = The reaction of an organism to its surroundings</p> Signup and view all the answers
