| A | B |
|---|
| microscope | an istrument that makes small objects look larger |
| compound microscope | a light microscope that has more than one lens |
| magnification | makes things larger |
| resolution | clearly distinguishes the individual parts of an object |
| cell | basic unit of structure and function in an organism |
| organelles | tiny cell structures that carry out specific functions within the cell |
| cell membrane | the layer that surrounds a cell, holds it together, and controls what enters and leaves |
| nucleus | the main part of a cell, controls the cell's activities, "brain" |
| nuclear membrane | the thin layer of tissue that surround and encloses the nucleus |
| endoplasmic reticulum | carry protines and other materials from one part of the cell to another |
| golgi bodies | receives proteins and other newly formed materials from the ER, and distributs them to other parts of the cell |
| ribosomes | produce protein for the cell, located on the ER |
| vacuole | storage area of the cell -water, food, waste |
| mitochondria | powerhouse of the cell where energy is produced |
| lysosomes | breaks down food and old cell parts |
| cytoplasm | clear, jelly-like material that contains all the cell organelles |
| cell wall | ONLY in plant cells, rigis outer covering gives the plant structure and shape |
| chloroplasts | ONLY in plant cells, contains chlorophyll and changes suns energy into foos for the cell |
| organism | any living thing, including all plants and animals |
| prokaryotic cell | cell that lacks a nucleus ex: bacteria |
| eukaryotic cell | cells that contain a nucleus ex: you |
| tissues | group of cells that perform a specialized function |
| organs | group of tissues that perform a specific function |
| organ systems | group of organs that perform a complex function |
| diffusion | movement of a substance from a place where there is more of it to a place where there is less of it |
| osmosis | the process by which a fluid passes through a membrane (ex: water through a cell membrane) |
| equilibrium | a situation in which forces or reactions are balnced and no overall change is taking place |
