| a microscope that uses a beam of visivle passing light of 1 or more lenses to magnifyand object | light microscope |
| a microscope that focuses a beam of electrons to magnify an object | electron microscope |
| the increase of an objects apparent size by using lenses or mirrors | magnification |
| microscopes ability to form images with fine detail | resolution |
| uses a needle like probe to measure differences in voltage cause by electrons tunneling to surface for viewing | scanning tunneling microscope |
| the theory that states that all living things are made up of cells, that cells are the basic units of orginisms, that each cell is multi cellular organism has a spesific job, and that cells only come frome existing cells | cell theory |
| a phospholipid layer that covers a cell's surface and acts as a barrier between the inside of the cell and its enviroment | cell membrane |
| the region of the cell with in the membrane that includes the fluid; the cytoskeleton, and all of the orgenelles except the nucleus | cytoplasm |
| the cytoplasmic netwrk of protein filaments that plays an essential role in cell movment, shape, and division | cytoskeleton |
| a cell orgenelle composed of RNA and protein; the site of prtein synthesis | ribosomes |
| an organism that consits of a single cell that does not have a nucleus or cell orgenelles | prokaryote |
| a rigid structure that surrounds the cell membrane and rovides support to the cell | cell wall |
| a long hairlike structue that grows out of the cell and enables the cell to move | flagellun |
| an organism made up of cells that have a nucleus enclosed by a memebrane, mulitple chromosomes and a mitotic cycle | eukaryote |
| in eurkaryotic cell, biology, a membrane band organelle that contains the cells DNA and that has a role in processes shc as growth , metabolism and reprocduction | nucleus |
| one the small bodies that found in the cyto plasm if a cell and that are spceialized ot preform a specific function | orgenelle |
| a hair like structure arranged in tightly packed in rows that projects from the surface of some cells | cilium |
| a lipid that contains phosphorus and that is a structural component in cell membrane | phospholipids |
| basic structure of a biological membrane composed of 2 layers of phospholipids | lipid bilayer |
| a system of membranes that is found in a cell's cytoplasm and that assists in production processing , and transport of proteins and in the production of lipids | endoplasmic reticulum |
| a small cavitor sac that contains materials in a eukaryotic cell;forms when part of the cell membrane surrounds the materials to be in to cell or transported with in the cell | vesicle |
| cell orgenlle that helps make and package materials to be transported out of the cell | gogi apperatus |
| a cell orgenelle that contains digestive enzymes | lysosome |
| in eukaryotic celss the cell orgenlle that is surrounded by 2 membranes and that is the site of cellular respiration wich provieds ATP | mitocondria |
