Unscramble the names of the organisms given and match the following.
$\begin{array}{cc}\text{Features}& \text{Organism}\\ \left(a\right)\text{Blood-filled coelomic cavity}& \left(i\right)\text{AAIRLLIF MWOR}\\ \left(b\right)\text{Pseudocoelomate}& \left(ii\right)\text{SSEEUOHIFL}\\ \left(c\right)\text{Water driven tube system}& \left(iii\right)\text{RILEV EKLFU}\\ \left(d\right)\text{Flatworm}& \left(iv\right)\text{HTRAFSSI}\end{array}$

• A. a-iii, b-i, d-iii, c-iv
• B. a-iv, b-iii, c-ii, d-i
• C. a-ii, b-i, c-iv, d-iii
• D. a-iii, b-ii, c-i, d-iv

Answer 1

The correct option is C a-ii, b-i, c-iv, d-iii

$\bullet$ Unscrambled words are: i) FILARIAL WORM, ii) HOUSEFLIES, iii) LIVER FLUKE, iv) STARFISH.
$\bullet$ Blood- filled coelomic cavity is the feature of phylum Arthropoda. The phylum consists of animals with jointed legs and have an open circulatory system. E.g., Cockroach, houseflies, etc.
$\bullet$ Nematodes are the only animals with pseudocoelom. E.g., Filarial worm, pinworm, etc.,
$\bullet$ Phylum Echinodermata consists of spiny skinned animals and have a water driven tube system for locomotion. E.g., Starish, sea urchin.
$\bullet$ Platyhelminthes are also called flatworms as they have a dorso-ventrally flattened body. E.g., Liver fluke, planaria, etc.
