biology - ANSWER: the study of living organisms and how they live
Atoms - ANSWER: smallest unit of an element; composed of electrons, protons, and
neutrons~join to make molecules
molecule - ANSWER: union of two or more atoms of the same or different elements
cell - ANSWER: the structural and functional unit of all living things
tissue - ANSWER: a group of cells with a common structure and function
organ - ANSWER: composed of tissues functioning together for a specific task
organ system - ANSWER: composed of several organs working together
organism - ANSWER: an individual; complex individuals contain organ systems
species - ANSWER: a group of similar, interbreeding organisms
population - ANSWER: organisms of the same species in a particular area
community - ANSWER: interacting populations in a particular area
ecosystem - ANSWER: a community plus the physical environment
biosphere - ANSWER: regions of the earth's crust, waters, and atmosphere inhabited
by living organisms
Energy - ANSWER: the capacity to do work
metabolism - ANSWER: All of the chemical reactions that occur within a cell
Sun - ANSWER: Ultimate source of energy for majority of life on earth
Photosynthesis - ANSWER: process by which plants and some other organisms use
light energy to convert water and carbon dioxide into oxygen and high-energy
carbohydrates such as sugars and starches
homeostasis - ANSWER: a constant internal environment
Characteristic 1 - ANSWER: Life is organized
, Characteristic 2 - ANSWER: Living organisms acquire materials and energy
Characteristic 3 - ANSWER: Living organisms are homeostatic
Characteristic 4 - ANSWER: Living organisms respond to stimuli
Characteristic 5 - ANSWER: Living organisms reproduce and have the potential for
growth
Characteristic 6 - ANSWER: Living organisms are (supposed by many) to have an
evolutionary history
reproduce - ANSWER: when organisms pass on their genetic information to the next
generation
as the fertilized egg grows into a fetus (BABY), or an acorn becomes a tree -
ANSWER: growth occurs
Growth - ANSWER: an increase in size and often in number of cells~part of
development
development - ANSWER: all the changes that occur from the time the egg is fertilized
until death
DNA (deoxyribonucleic acid) - ANSWER: contains the genetic info of all life
genes - ANSWER: short sequences of hereditary material that specify the instructions
for a specific trait
mutations (believed to be the basis of evolutionary change) - ANSWER: minor
variations in genes that can cause an organism to be better suited for the
environment
evolution (belief) - ANSWER: the process of change over time
natural selection - ANSWER: believed to be the mechanism by which evolution
occurs
domain - ANSWER: Most inclusive taxonomic category; larger than a kingdom
Bacteria and Archaea - ANSWER: contain prokaryotic, single-celled organisms that
lack a nucleus
Eukarya - ANSWER: Domain of all organisms whose cells have nuclei, including
protists, plants, fungi, and animals
plants - ANSWER: multicellular, photosynthetic organisms
