Chapter 1: Biology, The Essentials – Test
Bank by Marielle Hoefnagels
atom - Answer a particle of matter; composed of protons, neutrons, and electrons. an
organism consists of atoms, which form molecules.
molecule - Answer two or more atoms joined by chemical bonds; they form the organelles
inside of cells
organelle - Answer compartment of a eukaryotic cell that performs a specialized function
important to a cell's survival; types might include mitochondria, chloroplasts, etc.
tissue - Answer group of cells that interact and provide a specific function
organ - Answer two or more tissues that interact and function as an integrated unit
organ system - Answer two or more physically or functionally linked organs; your nervous
system is a good example since it uses nerve impulses to tell your muscles and organs what to
do
population - Answer interbreeding members of the same species occupying the same region
community - Answer group of interacting populations that inhabit the same region; multiple
individuals of the same species make up populations, and multiple populations form
communities.
ecosystem - Answer a community and its nonliving environment
biosphere - Answer part of Earth where life can exist. the biosphere includes all of the world's
ecosystems.
emergent properties - Answer quality that results from interactions of a system's components;
for example, a plant that is about to flower can be said to have their flowering as an emergent
property; seeds about to germinate, a butterfly in their cocoon, leaves about to fall from the
