Sexual reproduction occurs by conjugation or syngamy. 2. Name the different types of locomotion for protists. Pseudopodia, flagella, cilia, direct cell movements. 3. What is the arrangement of microtubules in cilium and flagella? The axoneme have microtubules usually arranged ina circle of 9 pairs of microtubules that encircle one pair. It is called a "9+2" arrangement. 4. The main organelle used in osmoregulation is the contractile vacuoles. 5. What are the different types of nutrition? Autotrophs make their own food from inorganic materials Heterotrophs obtain food from other organisms 6. Give an example of the Phylum Retortamonada. Giardia 7. Name the different colonial forms of the Volvocine series. Volvox, Chlamydomonas, Gonium, Pandorin~ Eudorina 8. What characteristic is unique to the Phylum CQlorophyta?

How do ToxiQlasma, CwtosQoridium, and Plasmodium vary the lifecycle for their purposes? Coccidea lifecycle is on the attached sheet. ToxiQlasma forms cysts in any host, but only enters the sexual stage in the intestines of cats. CwtosQoridium doesn't have a timed release of the new generations together. Their offspring have an individually timed release. Plasmodium are strictly blood borne, so their sexual cycle is done only in mosquitoes. 11. How are the nuclei of phylum Ciliophora different from other phyla? They are always multinucleate. They will have at least one macronucleus and micronucleus. 12.
