Question Answer
prokaryote cell pro means before and karyose means kernel as in a kernel of grain. prokaryotic means before a nucleus.
eukaryotic cell eu means true and karyose means kernel, eukaryotic means possessing a true nucleus.
bacteriophage a bacteriophage is a virus that attacks and destroys bacteria
lysis lysis is the destruction of a living cell
lysogenic infection one method by which viruses replicate. The virus's genetic material combines with the DNA of the cell it invades.
lytic infection one method by which viruses replicate. a virus injects its genetic material into a living cell, causing the cell to make copies of the virus. this method destroys the cell.
replication the process of making copies or duplicating; viruses increase in numbers through replication.
adenosine triphosphate (ATP) a chemical compound that living organisms use to store energy
bromothymol blue indicator is used to determine whether a solution is acidic: the blue color changes to yellow in the presence of an acid.
cellular respiration the cellular process that releases energy when food molecules are broken down in the presence of oxygen.
photosynthesis the cellular process through which plants and other organisms use energy from light to convert water and carbon dioxide into oxygen, sugars and starches.
products represented on the right side of the arrow in a chemical equation, are the ending substances in a reaction
reactants represented on the left side of the arrow in a chemical equation, are the starting substances in a reaction
active transport the movement of molecules into or out of a cell requiring the cell to use energy to move the molecules.
cell the basic functional and structural unit of all living organisms
diffusion the movement of a substance from an area of high concentration to an area of low concentration
homeostasis a state of balance or equilibrium. For example when cells move from one environment to another, they will go through osmosis, lose or gain water molecules to equalize the number of water molecules inside them and outside them.
passive transport the movement of molecules into or out of a cell. It does not require the cell to expend energy to move the molecules.
osmosis the diffusion of water across a semipermeable membrane (cell membrane) from regions of high water concentration to regions of low water concentration.
semipermeable membrane selectively permeable also, a membrane that allows small molecules and ions to diffuse into or out of it. The cell membrane is a semipermeable membrane.
carbohydrate a sugar, such as a monosaccharide, disaccharide or polysaccharide
lipid one of a family of biomolecule compounds that are insoluble in water, including fats, phospholipids and steroids
nucleic acid a polymer consisting of many nucleotide monomers: serves as a blueprint for proteins and through the actions of these proteins it controls all cellular activities.
protein a three-dimensional biological polymer constructed from a set of 20 different amino acids
group words vocabulary from the groups in class
