Verified step by step guidance

Understand the basic characteristics of annelids: Annelids are a phylum of worms known for their segmented bodies. This segmentation is a key feature that distinguishes them from other worm-like organisms.

Learn about body symmetry: Annelids exhibit bilateral symmetry, meaning their body can be divided into two identical halves along a single plane.

Explore the concept of a coelom: A coelom is a fluid-filled body cavity completely lined by mesoderm tissue. Annelids possess a true coelom, which provides space for organ development and contributes to their complex body structure.

Differentiate between types of body cavities: A pseudocoelom is partially lined with mesoderm, while a true coelom is fully lined. Annelids have a true coelom, not a pseudocoelom.

Recognize the correct description: Based on the characteristics of annelids, the correct description of their body plan is 'Segmented with a true coelom.' This highlights their segmented structure and the presence of a true coelom.
