30
Q

What is the difference between hemimetabolous and holometabolous metamorphosis?

A

Hemimetabolous is when it doesn’t morph into a whole new body from but holometabolous does

31
Q

What is the nerve ring for Echinodermata?

A

The nervous system ring where branches arise from

32
Q

What is the water vascular system in Echinodermata?

A

Central ring where five radial canals extend out of the body and arm canal it uses hydraulic power to operate a multitude of tiny tube feet for locomotion and food capture

33
Q

What is the madreporite in Echinodermata

A

Sieve-like plate on the animals surface, and flows through a tube to the central ring canal

34
Q

What is the radial canal in Echinodermata

A

Extends from the ring canal

35
Q

What are the lateral canals in the Echinodermata

A

Muscular sacs that lie at the base of tube feet

36
Q

What is the ampulla in Echinodermata

A

Lie at base of tube feet and when they contract the fluid is prevented from entering the radial canal by a one way valve

37
Q

What is the tube foot in echniodermata

A

Where fluid is directed from the ampulla, fluid makes it extend for locomotion

38
Q

What are the ossicles in Echinodermata
