Across
- 1. an organism that must consume other organisms for energy

- 4. green algae share many characteristics with land plants, but do not produce embryos or inhabit land
- 5. process by which cells move large molecules or particles into the cytoplasm from the outside
- 8. one or more plastids and are usually photosynthetic
- 9. when partners in a symbiosis both benefit
- 10. an organism that can produce its own food
- 11. Groups of protists whose members generally
- 13. long propelling extensions from a eukaryotic cell that allow for movement
- 14. is a protist that is similar to fungi and can be seen in figure 20.2
- 15. developed when an ancient protist consumed an early bacteria
- 16. photosynthetic plankton
Down
- 2. small organisms that swim or float in water - often protists.
- 6. protists that lack plastids and behave similarly to a fungus
- 7. algae live within a coral reef and provide its color
- 12. _____________ plastids are surrounded by two membranes.
