| A | B |
| cell membrane | controls what enters and leaves the cell; "gatekeeper" or selectively permeable |
| cytoplasm | jelly like substance that fills the cell and holds organelles in place |
| nucleus | "brain" or control center of the cell; genetic material is located here |
| genetic material | DNA: directions for cell processes |
| chromosome | wound up DNA |
| chromotin | DNA that is not wound up |
| nucleolus | place inside the nucleus where ribosomes are made |
| mitochondria | "powerhouse" of the cell; releases energy stored in food |
| respiration | energy stored in the cells is released with the help of oxygen |
| endoplasmic reticulum "ER" | transports molecules around the cell "subway system" |
| ribosomes | interpret directions from DNA to make proteins for the cell |
| Golgi Bodies | package products from the ER to be transported outside of the cell |
| vacuole | storage: water, waste products and food |
| cell wall | gives support and shape to cell; made of cellulose; |
| chloroplasts | contain chlorophyll to give plants their green color; photosynthesis occurs here |
| unicellular | made up of only one cell; cell does all necessay jobs to keep it alive |
| multicellular | made up of many cells; each with specific jobs to keep the organism alive |
| homeostasis | a stable internal environment |
| autotrophs | organisms that make their own food |
| heterotroph | organisms that cannot make their own food |
