Document Summary
Unicellular, not a clade, ancestral, not a taxonomy (official classification) Clade eumetazoa (true tissues, no sponges but some basal members) Phylum is a taxonomic category (we belong to the phylum chordata) Clade is a group of descendants of a common ancestor. So all your family members that are descended from your maternal grandmother form a clade (your mother, but not your father, your mother"s sisters and brothers, their children, your sisters and brothers, and you) Eukaryotes, one prokaryote engulfed and merged with another prokaryote. Using to be free living prokaryotes of their own. At lease 1 motile stage in life cycle. Nucleus - membrane bound, contains dna as chromo, nucleoli often present. Mitochondria - energy using oxygen, has its own dna. Hydrogenosomes - substitute mito for when oxygen is absent. Kinetoplasts - derivates of mito in some phyla. Parabasal bodies - structures with similar secretory function in some phyla.
