name the phylum with solid body plan
Answers
Answer:
A body plan, Bauplan (German plural Baupläne), or ground plan is a set of morphological features common to many members of a phylum of animals.[1] The vertebrate body plan is one of many: invertebrates consist of many phyla.
This term, usually applied to animals, envisages a "blueprint" encompassing aspects such as symmetry, segmentation and limb disposition. Evolutionary developmental biology seeks to explain the origins of diverse body plans.
Body plans have historically been considered to have evolved in a flash in the Cambrian explosion, but a more nuanced understanding of animal evolution suggests gradual development of body plans throughout the early Palaeozoic.
Phylum mollusca has its body covered with solid body plan.

- They have closed circulatory system and the organism have the production of energy that takes place earlier than the the mouth. They are mostly aquatic in nature.
