| 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 molecules 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 |
| transcription | 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 acids 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 between cells that provides a pathway for substances |
| peroxisomes | detoxify harmful substances such as alcohol and free radicals |
