Protists
Across
1. Contains DNA and controls a protist's metabolism & development
3. Long whip-like tail to help Euglena move
4. Asexual method of reproduction in protists where the cell divides into two identical
cells

6. Protective shell in marine foraminiferans
10. Phylum for water molds
12. Colonial protist showing division of labor and some specialized cells
14. Phylum of brown algae
15. Nucleus in protists that is involved in conjugation or exchange of genetic material
18. Phylum for red algae
19. Sexual method of reproduction involving two protists and producing genetically
different offspring
21. Protists and other organisms that can make their own food
24. Population explosion of poisonous red algae along ocean shorelines
25. Protist transmitted by mosquitoes that causes malaria
27. Light capturing pigment in algae
28. Grove lined with cilia in paramecia where food enters and passes through the mouth
pore
29. Cytoplasmic extensions used by an amoeba to move and feed
32. Unicellular or simple multicellular eukaryotes that do not fit into any other kingdom
34. Domain containing protists
Down
2. Phylum containing green, chlorophyll-containing algae
7. Process whereby the mitochondria and chloroplasts of protists arose
8. Flagellated protist that causes sleeping sickness and is carried by insects
9. Tiny hairs used by some protists like the paramecium for movement
11. Polysaccharide from red algae used in science labs to grow bacteria
13. Contain a nucleus and membrane-bound organelles
14. Freshwater protist shaped like a slipper that moves by cilia
16. Vacuole that pumps out excess water in some protists
17. Unicellular protist with a two-part shell made of silicon dioxide (glass)
20. fungal like protists that secrete digestive enzymes and then absorb their food
22. Number of nuclei in ciliates like the paramecium
23. Clear, elastic protein layer around the cell membrane of ciliates like the paramecium
26. Ability of some protists to produce their own light
29. animal-like protists
30. Group that makes up most of the unicellular algae and serve as the food for most
aquatic food chains
31. Moving by pseudopodia is called this type of movement
33. Large multicellular algae also called kelp
