Mesozoa are simple, multicellular organisms typically composed of a few cell layers and are often categorized as having a bilateral symmetry, although some exhibit a more simplified structure. They generally lack specialized tissues and organs, consisting mainly of elongated, worm-like forms. Placozoa, on the other hand, are even simpler, consisting of a flattened, multicellular body that is only a few cell layers thick, with a dorsal and ventral side, and exhibit a unique, amorphous body plan without true symmetry. Both groups represent some of the most primitive forms of multicellular life, showcasing early evolutionary traits.

What is a type of body plan that has no definite shape?

An example of a body plan with no definite shape is an amoeboid body plan found in unicellular organisms like amoebas. These organisms lack a fixed structure and can change shape constantly by altering the distribution of their internal components.


What genetic factors might be responsible for a change in an organism's body plan?

Changes in body plan can be influenced by mutations in key developmental genes, such as Hox genes, which regulate the spatial organization of body structures. Alterations in regulatory genes, like transcription factors, can also impact body plan formation. Additionally, changes in gene expression patterns during development can lead to modifications in the body plan of an organism.

Animals whose basic body plan can be described as a tube within a tube are the?

Animals whose basic body plan can be described as a tube within a tube are the bilaterians, including insects, mammals, reptiles, and birds. This means they have a central digestive tube (gut) within a central nervous system. This body plan allows for efficient organization of internal organs and specialization of body regions.


Which phylum of animals has a body plan that is essentially a tube within a tube?

The phylum that has a body plan that is essentially a tube within a tube is the Phylum Platyhelminthes, which includes flatworms. They have a simple body structure with a digestive tract that is a tube running from mouth to anus along the central axis of their body.

Are cnidarians protostomes or deuterostomes?

Although most of the animal phyla are included in the deuterostomes and protostomes, cnidaria, porifera, placozoa and ctenophora are not included in the group of animals know as Bilateria (which contains the deuterostomes and protostomes). Cnidarians and ctenophores are in a group called Radiata, and Porifera and Placozoa are in the group known as Parazoa.
