| A | B |
|---|
| compound light microscope | major tool of cell study; uses two lenses to enlarge |
| electron microscope | most powerful microscope; can only be used on dead organisms |
| dissecting microscope | gives a 3-dimensional image for dissecting; very low power |
| ultracentrifuge | separates cell parts on the basis of density |
| microdissection instruments | tiny instruments used for the dissection of individual cells and/or transfer of cell organelles |
| staining | technique used to see cell organelles which may not be clearly visible |
| plasma (cell) membrance | a double lipid layer with proteins floating in it; to transport materials in and out of cell |
| cytoplasm | fluid-like material that fills the cell; organelles suspended in it |
| nucleus | control center of the cell; contains genetic material; surrounded by nuclear membrane |
| nucleolus | found inside the nucleus; helps make ribosomes |
| endoplasmic reticulum | main function is to perform intracellular transport |
| ribosomes | make protein for the cell (protein sysnthesis) |
| mitochondria | food such as glucose is broken down here nd energy is produced (cellular respiration) |
| golgi complex | synthesizes, packages, and secretes cellular products |
| lysosomes | hold digestive enzymes |
| vacuoles | provide storage for the cell |
| food vacuoles | found only in unicellular organisms; help digest food |
| contractile vacuole | found in unicellular organisms; help maintain water balance |
| centrioles | only found in animal cells; help cell divide; found near nucleus |
| chloroplasts | found in plant and algae cells; site of photosynthesis; contain chlorophyl |
| cell wall | found in plant and algae cells; support and protect the cell; non-living |
