cell fnct & strctr
cell structure and function
| Term | Definition | hints/examples |
|---|---|---|
| cell | smallest unit of life | |
| cell membrane | the structure which defines the boundaries of any cell, also found around eukaryotic organelles | |
| cell wall | a rigid structure which surrounds plant, fungi and bacteria cells | |
| chloroplast | the organelle which converts light energy into chemical energy (sugar) by photosynthesis | |
| cilia | small extensions of a cell's cytoskeleton structures which 'beat' to create movement | |
| cytoplasm | the contents of a cell between the nucleus and cell membrane (in eukaryotic cells) | |
| cytoskeleton | those structures of a cell which allow it to move, move substances within, or give the cell its shape/structure | microtubules, microfilaments and intermediate filaments are examples |
| eukaryotic | a cell that has a nucleus and other membrane bound organelles | |
| flagella | a long cytoskelton structure which 'whips' causing movement | |
| golgi apparatus | a packaging organelle of eukarytotic cell | |
| lysosome | a eukaryotic organelle which contains digestive enzymes to digest food or cell parts | "-lys" means to break apart, digestion is to break apart |
| magnification | the increase in apparent/perceived size of an object | |
| microscope | a tool which magnifies objects | "micro-" means small |
| mitochondria | a eukaryotic organelle responsible for converting chemical energy (sugar) into usable cell energy (ATP) | |
| nucleolus | a part of the eukaryotic nucleus that is responsible for ribosome production | "-eolus" means little, as in little nucleus |
| nucleus | the eukaryotic organelle responsible for housing the cell's DNA | |
| organelle | a eukaryotic cell part which is surrounded by a membrane and has a specific life function | "-elle" means little, as in little organ |
| prokaryotic | a cell type that does not have a nucleus of other membrane bound internal parts | |
| resolution | the clarity at which the smaller parts of an object are viewed | |
| ribosomes | a cell part which is responsible for the production of proteins that are typically used inside of the cell | |
| rough endoplasmic reticulum | a eukaryotic cell part responsible for the production of proteins that are typically used outside of the cell | the 'r' in rough indicates that ribosome are present in the rough endoplasmic reticulum |
| smooth endoplasmic reticulum | a eukaryotic cell part responsible for the break down of harmful substances and the production of lipids | |
| vacuole | a eukaryotic membranous storage 'sac' | |
| vesicles | typically a structure that transports substances to and from the golgi apparatus from other cell parts | |
| bacteria | a group of prokaryotic organisms, often associated with disease or decay |
