Across
- 4. a nonliving structure, made of a strand of DNA or RNA & surrounded by a protein coat; replicates itself inside host cells
- 7. a close, long-term relationship between two species
- 9. an animal-like organism in the kingdom Protista that usually can move & and doesn’t perform photosynthesis
- 10. the slender filaments of a fungus that secrete enzymes for use in external digestion
- 11. a type of asexual reproduction caused by a physical disturbance that breaks a colonial organism; observed in algae
- 12. a kingdom than contains organisms that produce spores, lacks chlorophyll, has cell walls, & obtains nourishment by absorption
- 13. the plantlike organisms in kingdom Protista that can perform photosynthesis and are usually unable to move themselves
- 14. a fungus & and alga that live together symbiotically for mutual benefit & appear as a single organism
Down
- 1. a method of asexual reproduction seen in bacteria in which the genetic material is replicated and the cell splits
- 2. a kingdom that contains prokaryotic organisms that live in extreme environments & lack some compounds found in the cell walls of eubacteria
- 3. a kingdom that consists of mostly single-celled eukaryotes than aren’t classified as plants, animals, or fungi
- 5. a microscopic, unicellular, prokaryotic organism in Kingdom Eubacteria Archaebacteria
- 6. a kingdom that contains the majority of prokaryotic organisms
- 8. a type of sexual reproduction in many unicellular & colonial organisms for the purpose of exchanging portions of their genetic material
- 9. microscopic organisms, primarily protozoans and algae, that float near the ocean’s surfCe & are a key food source in the ocean’s food chain
