CHOR-DATA |
|
po-ri-fera |
generally none symmetry; asexual (budding) or sexual( no specialized organs, her-map-ph-ro-ditic) internal (sperm find eggs between cell layers), none nervous system no sense organs; none digestive system intracellular digestion; none circulatory,respiratory,excretory system. no body cavity, segmentation, appendages. |
|
cni-da-ria |
RADICAL;asexual (budding) or sexual(usually her-map-ph-ro-ditic often with transient organs) usually external. NERVE NET SIMPLE SENSORY CELLS SOME HAVE EYES/STATOCYSTS. INCOMPLETE (Gas-tro-vascular cavity)intra-and EXTRA- cellular digestion none none none...(CORAL has external skeleton) |
|
Echi-no-der-mata |
general radial in adults, bilateral in larvae;usually sexual sometimes asexual, usually separate sex external(no specialized organs in lilies-sessile) SIMPLE BRAIN(nerve ring)with nerves ,sense organs; complete extracellular digestion; open but much reduced, 1- chambered heart; gills;no excretory system;coelom present; unique water-vascular system:locomotion(tube feet) respiration, circulation excretion. Endoskeleton with calcium(much reduced in sea cucumbers) no segmentation |
|
Chor-data |
bilateral, sexual usually separate internal or external; brain with dorsal hollow nerve cord and ganglia, sense organs;complete extracellular digestion;closed heart with 2 or more chambers, gills or lungs, ne-ph-ridia, coelom present ; noto-chord (sometimes lost in adult) endoskeleton (sometimes in calcium) muscular,post-anal tail(may lost in adults) usually with paired appendages, segmentation reduced or absent |
