Assertion : Tube feet are characteristic organs of Echinodermata. Reason : Tube feet play an important role in reproduction.

Assertion : - Ca^(++) play an important role in the muscle contraction. Reason :- Calcium bind with a subunit of troponin on actin filaments and thereby remove the masking of active sites for myosin.

Assertion : Ca^(2+) plays important role in the muscle contraction. Reason : Ca^(2+) Combines with troponin chain, displacing tropomyosin allowing the myosin head part to combine with actin to from actomyosin complex .
