  1. 2. A tiny, nonliving particle that invades and then reproduces inside a living cell.
  2. 3. A system for giving each organism a two-word scientific name that consists of the genus name followed by the species name
  3. 5. A diagram that is based on patterns of shared, derived traits and that shows the evolutionary relationships between groups of organisms
  4. 7. Study of how organisms are named and classified.
  5. 8. A kingdom made up of complex, multicellular organisms that lack cell walls, can usually move around, and quickly respond to their environment.
  6. 10. Kingdom of multicellular photosynthetic autotrophs that have cell walls containing cellulose
  7. 13. injection of a weakened or mild form of a pathogen to produce immunity
  8. 14. Domain of all organisms whose cells have nuclei, including protists, plants, fungi, and animals

Down
  1. 1. Kingdom composed of eukaryotes that are not classified as plants, animals, or fungi
  2. 4. a key for the identification of organisms based on a series of choices between alternative characteristics

  7. 15. Domain Eukarya; heterotrophic; unicellular/multicellular; asexual/sexual reproduction
  8. 16. cycle a viral reproductive cycle in which copies of a virus are made within a host cell, which then bursts open (lyses), releasing new viruses
