NEET BIOLOGY

Detailed explanation-1: -Segmented worms (phylum Annelida) are the most complex animals with worm-like body plans. A study of worms can illuminate a possible history of how some organ systems and body features evolved. Worms are invertebrate animals with bilateral symmetry.

Detailed explanation-2: -Annelids display bilateral symmetry and are worm-like in overall morphology. They have a segmented body plan where the internal and external morphological features are repeated in each body segment. Metamerism allows animals to become bigger by adding “compartments, ” while making their movement more efficient.

Detailed explanation-3: -Annelida. Annelids are segmented worms, known for having bilateral symmetry and a segmented body. Leeches are also examples of annelids, as are some types of marine worms.

Detailed explanation-4: -The annelids include earthworms, polychaete worms, and leeches. All members of the group are to some extent segmented, in other words, made up of segments that are formed by subdivisions that partially transect the body cavity. Segmentation is also called metamerism.

Detailed explanation-5: -Annelids display bilateral symmetry and are worm-like in overall morphology. Annelids have a segmented body plan wherein the internal and external morphological features are repeated in each body segment.
