CellThe smallest unit of life. Fluid -filled spaces bound by a membrane. when first formed they all contain DNA and other micomolecules that are organized to grow, reproduce, and respond to changes in the environment.Prokayotes Eukaryotes MatterAnything that has mass and takes up space BioticLiving or having lived.They use energy and raw materials to grow, sense, and respond to changing environments.They reproduce.They consist of one or more cells.AbioticNon-living and never been living.Rain Rocks Sunlight AtomBasic unit of matter that cannot be broken down any further without losing its unique properties.Each atom consists of a dense nucleus surronded by a cloud of electrons.Building block of all matter MoleculeTwo or more atoms held together by chemical bonds MacromoleculesA very large organic molecule composed of many smaller molecules MicroorganismSingle celled life forms OrgansGroups of tissues that work together to perform a specific function or related functions.Heart Lungs Kidneys Organ systemGroup of organs in the body that work together to perform a specific function.OrganismAny living thing PopulationA group of individuals that belong to the same species and live in the same area and are likely to breed with one another.

CommunityA group of interdependent organisms inhabiting the same region and interacting with each other. All of the populations interacting with each other within a specific area.EcosystemAll the organisms that live in an area, together with their nonliving environment.BiomeA large natually occuring community of plants and animals occupying a major habitat.Tropical forest Artic tundra BiosphereAll areas on, within, and around the planet Earth that are capable of supporting life; land, water, and the atmosphere.Identify the levels of biological organization from atom to biome.Atoms Molecules Cells Tissues Organs Organ systems Whole organisms Populations Communities Biomes Escosystems Biosphere TissueA group of similar cells that perform the same function within the organism.OrganelleA specialized structure within a cell formed when a specific set of molecules bond, creating a subunit that has a specific function.Nucleus Scientific inquiryThe application of scientific observation, experimentation, and scientific method to study, intrepert, and and predict natural phenomena in the world around us.ElectronegativityThe tendency of an atom to hold shared electrons more close to its nucleus.Atoms like oxygen have a high electronegativity. This means when oxygen forms a covalent bond with an atom of lower electronegativity, the shared electrons will stay closer to the oxygen atom than the other atom. Strongly electronegative atoms bonded to weak electronegative hydrogen atoms, in a molecule, results in hydrogen bonding. The most important stongly electonegative elements in biological systems are oxygen and nitrogen.ElectronA negatively charged subatomic particle that is found in the space outside the nucleus of an atom.NeutronA subatomic particle that has no charge and that is found in the nucleus of an atom

ProtonA subatomic particle that has a positive charge and that is found in the nucleus of an atom Chemical bondsAttractions between atoms that holds atoms and molecules together.Covalent bonds- two atoms share electrons Ionic bonds-two oppositely charged atoms stick together Covalent bondSharing of electrons between two atoms Ionic bondThe attraction between oppositely charged ions Hydrogen bondA type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule.AdhesionThe attraction of water molecules to molecules other than water. Capillary action (in which water will spontaneously climb up the walls of a tube without pumping) is a result of the adhesion of water molecules with the surface of the tube containing the water.Surface tensionThe capacity of a liquids surface to resist being ruptured when placed under tenision or stress.Cohesionthe sticking together of particles of the same substance. liquid is cohesive and forms dropets because of its hydrogen bonds.Solutessubstances dissolved in a liquid SolutionA mixture that forms when one substance dissolves another.SolventIn a solution, the substance in which the solute dissolves.HydrophobicWater fearing HydrophilicWater loving Amino acidsMolecules containing an amine group, a carboxylic acid group, and a specific side-chain.Building blocks of proteins.GlucoseA simple carbohydrate (monosaccharide) with the chemical formula of C6H12O6.This is the primary product (output) of photosynthesis and the primary reactant (input) of cellular respiration.Sugar
