Chapter 28: Q. 12 (page 771)

Annelids have a:

a. pseudocoelom.

b. true coelom.

c. no coelom.

d. none of the above

Short Answer

Expert verified

Option b is the correct answer.

Step by step solution

01

Introduction

Worms with segmented bodies that belong to the phylum Annelida can be found in habitats on land, at sea, and in freshwater. The presence of dampness or water is essential for their survival in terrestrial settings. Leeches, polychaete worms, and earthworms make up this phylum.

02

The explanation for the correct answer.

Animals are classified according to whether or not they have Coelom, which is a characteristic. Triploblasts have an interior cavity called a coelom, which develops from the mesoderm. So, Annelids has.

03

The explanation for the incorrect options.

Pseudocoelomates get a portion of their body cavity from mesoderm and a portion from endoderm tissue. Pseudocoelomates, not annelids, are roundworms. Annelids have the protein coelom.
