osmosis | movement of water from high concentration to low concentration |
ribosomes | found attached to ER or free floating |
exocytosis | type of active transport that moves materials out of the cell |
solution | homogeneous mixture of 2 or more components |
facilitated diffusion | passive transport that uses integral proteins to move mol's across |
diffusion | putting food coloring in a beaker of water would be an ex of this |
pinocytosis | refers to cell "drinking" or bringing in a liquid |
transription | process of making mRNA |
nucleus | where mRNA is made |
tRNA | what goes out into the cytoplasm to find an amino acid |
protein | chain of amino acids |
translation | assembling of amino acides into a protein |
double helix | word used to describe structure of DNA |
chromatin | unwound form of chromosomes |
interphase | cell spends most of its time here |
nitrogen base pairs | these make up the rungs of the dna molecule |
nucleotides | repeating subunits of DNA |
mitochondria | only double membraned organelle |
hydrophobic | repels water |
hypotonic solution | causes a cell to swell |
isotonic solution | contains the same concentration of solutes as inside the cell |
DNA helicase | enzyme that unzips dna during dna replication |
uracil | base found in rna, not dna |
anaphase | when chromatids are pulled apart and move to opposite poles |
nucleus | control center of the cell |
interstitial fluid | fluid located betw cells that provides a pathway for subst's |
peroxisomes | detoxify harmful subst's such as alcohol and free radicals |
