| Term | Definition |
|---|
| cytoplasm | a jellylike fluid inside cell in which organelles are suspended |
| rough endoplasmic reticulum | endoplasmic reticulum studded with ribosomes |
| smooth endoplasmic reticulum | endoplasmic reticulum lacking ribosomes; creates lipids |
| vesicle | a sac made of membrane attached to the golgi body |
| ribosomes | "factories" that make proteins; made in nucleolus |
| golgi body | transports proteins; attached to vesicle |
| mitochondria | "powerhouse"; nutrients are converted to energy |
| nuclear membrane | protective membrane surrounding nucleus |
| chromatin | contains genetic material; directs functions of cell |
| nucleolus | a small body of protein in a cell nucleus; produces ribosomes |
| nucleus | control center of cell, "brain" of cell |
| cell membrane | thin membrane around the cytoplasm of a cell; "window screen" |
| chloroplasts (only plants) | captures energy from sunlight to use to produce food for the cell |
| cell wall | protective, strong, flexible layer around cell made of cellulose, allows objects to pass through |
| centriole | located in cytoplasm; involved in mitosis |
| lysosomes | "cleanup crew"; breakdown old cell & big food particles |
| vacuole | contains food, water, & waste; found in cytoplasm |
| cells | the body where organelles are kept in |
| organelles | the bodies inside the cell that play vital roles |
| magnification | allows you to see specimen larger than they really are |
| resolution | the ability to clearly distinguish individual parts of an object |
| cell theory | three statements that will always be true about cells |
| Hooke's Microscope | compound microscope in 1663 |
| Van Leewenhoek's Microscope | simple microscope in 1683 (magnified 266x) |
| Schleiden | 1st discovered all plants are made up of cells |
| Schwann | 1st discovered all animals are made up of cells |
| Virchow | 1st discovered all cells are made from other cells |
| Janssen | crmuated first compound microscope in 1590 |
| compound microscope | microscope with more than 1 lens |
| modern compound light microscope | created in 1886 (magnified 1000x) |
| scanning electron microscope (SEM) | magnified 150,000 times |
| transmission electron microscope (TEM) | only dead specimen (500,000 times) |
| Robert Hooke | first discovered and named "cells" |
| Van Leeuwenhoek | first discovered bacteria, or protozoa |
| how electron microscopes work | uses electron beams instead of natural light, |
| how total magnification is calculated | multiplies eyepiece lens by objective lens |
| bacterial cells | cell that has no nucleus, and no ribosomes |
| specialized cells | a cell where different organelles have different jobs in the cell |
| eyepiece | contains lens that magnifies about 10x |
| body tube | separates eyepiece lens from objective lens |
| nosepiece | allows eyepiece lens and objective lens to move |
| high power objective lens | magnifies around 40x |
| low power objective lens | magnifies around 10x |
| stage | supports slide in use |
| stage clip | holds slide in place |
| mirror | reflects light upward through diaphragm |
| base | supports microscope |
| arm | supports body tube |
| fine adjustment knob | focuses with high power objective lens |
| coarse adjustment knob | focuses with low power objective lens |
| diaphragm | controls amount of light passing through |
| compound microscope | microscope with more than one lens |
