BIOS 1120 Chapter Notes - Chapter 20: Amoeboid Movement, Brown Algae, Red Algae
Document Summary
Bios 1120 - chapter 20 - the diversity of protists. Higher eukaryotes (plants, fungi, and/or animals: multicellularity; cell motility (via cilia, flagella, or amoeboid movement); ingestion; A clade is a group consisting of all of the descendants of a particular common ancestor. Protists are eukaryotes, but do not include plants, animal, or fungi. Chlamydomonas (page 160) with that of a human. Unicellular, sexual protists like chlamydomonas can use sexual reproduction when nutrient deprivation induces mating/fertilization and meiosis. It reproduces asexually by mitotic division of haploid cells. Specialized haploid reproductive cells fuse to form a diploid cell. Meiotic cell division then immediately produces four haploid cells, usually with different genetic compositions. Humans do not have the choice to reproduce asexually: give examples of human diseases that are caused by particular protists. Giardia causes intestinal issues from the formation of cysts. Malaria is caused by parasitic (plasmodium) protists that form infectious spores.
