| Lysogenic cycle | -does not happen with every virus, -virus lies dormant until conditions are right, -virus attaches to host cell's chromosomes, -environmental stimulus sends viral DNA into lytic cycle |
| pathogens | organisms that cause a disease |

| cartilaginous | slightly movable; bones are attached by cartilage |

| cambium | makes new xylem and phloem cells |
| node | areas where side branches and leaves develop |
| tubers | underground food storage |
| bulbs | also underground food storage |
| runners | side shoots which grow out from the parent plant |
| leaves | produce food for the plant that is either used right away or stored for later use |
| receptacle | base of the flower where all the other sexual parts of the flower join together at the stalk |
