Which of the following options does correctly represent the characteristic features of phylum Annelida?
Options
- ATriploblastic, unsegmented body and bilaterally symmetrical
- BTriploblastic, segmented body and bilaterally symmetrical
- CTriploblastic, flattened body and acoelomate condition
- DDiploblastic, mostly marine and radially symmetrical
Correct answer
B. Triploblastic, segmented body and bilaterally symmetrical
Step-by-step solution
In Annelids, it is divided into a number of segments or metameres. The successive segments of the body are separated externally by ring-like constrictions called annuli. They are eucoelomates.
The body is made up of three layers, it is triploblastic.
The body of annelids can be divided into two equal halves by a single plane of symmetry, and thus are bilaterally symmetrical.
