Coelom forms by mesodermal out-pocketing of the primitive gut-enterocoelous.Indeterminate-stem cells are produced whose fates are not fixed at the time of division.Radi

Primitive gut

Helps control hydrostatic pressure in the water vascular system

Help with locomotion-contract to close valves & force water into the tube feet, which extend & adhere to the substrate.

Organ that produces gametes.

Calcite plates

In Deuterosomes, what does the blastopore become?

In protosomes, what does the blastpore become?

What is the circle of teeth called at the center of echinoidea? (Not Aristotle's Lantern, the other name)

Channels to help move food from aboral surface to oral surface and the mouth

This is an opening that typically develops into the anus in deuterostomes and the mouth in protostomes.

Name the type of development this describes: A developmental mode distinguished by the development of the anus from the blastopore.

Name the type of development this describes: characterized by radial cleavage and by the body cavity forming as outpockets of mesodermal tissue

What is the name for the extensions of an echinoderm's water vascular system which functions in locomotion and feeding?

What is the name for the network of hydraulic canals unique to echinoderms that branches into extensions called tube feet?

In this form of cleavage, cleavage planes are either parallel or perpendicular to the axis of the embryo

This type of cleavage allows each cell produced by early cleavage divisions to retain the capacity to develop into a complete embryo

In asteroidea, water can flow in or out of the water vascular system into the surrounding water through this structure.
