Document Summary

Giardia duodenalis: has mitosomes, apicomplexans: usually parasites of animals, have complex of organelles to penetrate host at apex of cell, 4 membranes and cyanobacterial dna, yet more evidence of endosymbiosis. Often require 2 or more host species: eg. plasmodium, organism that causes malaria, lives in flies, and in vertebrates. Use of insecticides and drugs have helped greatly diminish number of cases of malaria. Flagellated sperm (but still travels in pollen grain). Mostly less than 1 m high, a few small trees. Flagellated sperm, and sometimes pollinated by insects, two unusual characteristics in gymnosperms. Seeds and leaves poisonous: phylum coniferophyta: have cones (clusters of sporophylls), big trees usually, leaves are needles, scales or flat leaves. Most are evergreen, some are deciduous (drop needles in the fall). Bark beetles are a problem for these species: pine resin (aka pitch): like sap, for coniferophytes.
