Document Summary
Opisthokonts defined by a single, posterior flagellum. Recall that deeper relationships among eukaryotes are unresolved. Amoebozoans = feed by endocytosis (transferring cells by engulfing them), living as predators, parasites or scavengers molds. Ex of amoebozoans: loboseans, plasmodial slime molds, cellular slime. Opistho [posterium] kont [flagellum: amoebozoa are a disparate group, with a lot of. Some do not have typical amoeboid morphology or movement. Key points: 1) amoeboid body morphology has evolved multiple. Cell body (head), microvillis (tails), flagellum (beats for movement) (looks. Choanoflagellates are the sister group of metazoa: collar cells (choanocytes) also seen in sponges, dna sequence data, homologous cell signaling and adhesion genes times independently variation in life history and morphology. Choanoflagellates = small group of aquatic, heterotrophic eukaryotes like a hairy sperm) What are the features of animals? life cycle, blastula stage in development, determinate growth. Cells attach to each other of the ecm. Multicellularity, unique cell-to-cell junctions, extracellular matrix, diplontic.
