BIOL 371 Lecture Notes - Lecture 3: Blastula, Polyphyly, Desmosome
Document Summary
3 diagnostic characteristics . only found in animals: develop from a blastula , egg cell subdiv in half , then 488 untill hollow ballot cells called blastula certain extracellular matrix molecules (e. g. the proteoglycan collagen ) " multicellular eukaryote: fung 12 1 + animal 5- opisthokonta, paraphy. la/-ic=proraryoteslsingcel1. chemoheterotrophic igetchemfeedon from something diff eukaryotes ) . simlvlolorg rather than a named group. opisth0r0nt= animals: motile cat some life stage ) - _ can move atleast one stage if not all . se site. Cell memm contact adjacent cell memmlno cell walls ) , not true 4 plants eat other org where can"t move but always small. Sense and respond to the environment: monophyletic: everything in group comes from single coman , two tips that don"t have com : polyphyletic. Certain extracellular matrix molecules (e. g. the proteoglycan collagen ) > mat outside cell that were made by the cell ( just live outside )
