BIOL 150 Chapter Notes - Chapter 30: Paraphyly, Plasmodium, Phytophthora Infestans
Document Summary
Algal bloom - occurs when a unicellular species" population grows rapidly and reaches high densities in an aquatic environment. Diatoms - photosynthetic protists that rank among the leading primary producers in the oceans simply because they are so abundant. dinoflagellates - photosynthetic, toxin-producing protists that cause harmful algal blooms. Eukarya - eukaryotes range from single-celled organisms that are the size of bacteria to sequoia trees and blue whales. Hypothesis about earliest eukaryotes - that the earliest eukaryotes were probably single-celled organisms with mitochondria, a nucleus and endomembrane system, and a cytoskeleton, but no cell wall. Iron (in regards to carbon cycle) - fertilizing the ocean with iron may speed up the carbon cycle. Malaria - caused by five species of the parasitic protist plasmodium. The cell types that make up each stage of the plasmodium"s life cycle are each specialized for infecting a specific host cell. Plasmodium has evolved resistance to drugs used to control its growth.
