What is the tube within a tube body plan?, Most animals have a body plan best described as a “tube–within-a-tube“. This plan calls for two openings: one for food to enter the body (mouth), one for wastes to leave the body (anus). The tube–within-a-tube plan allows specialization of parts along the tube, such as a stomach, intestine, etc.
Furthermore, Do flatworms have a tube within a tube body plan?, Acoelomate animals (like flatworms and flukes) do not have a coelom (or body cavity) produced during preadult development. Pseudocoelomate animals (like roundworms) have a body cavity but it does not develop from splitting of the mesoderm.
Finally, Which organism would you classify as an animal?, All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs; they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores, herbivores, omnivores, or parasites.
Frequently Asked Question:
What type of symmetry is most common in the vertebrate group?
All vertebrates are bilaterally symmetrical with two pairs of appendages – limbs, fins, wings, etc. In comparison with invertebrates vertebrates have more developed organ systems. They have higher nervous system, which is divided into central and peripheral nervous system.
What type of symmetry do vertebrates have?
All vertebrates are bilaterally symmetrical with two pairs of appendages – limbs, fins, wings, etc. In comparison with invertebrates vertebrates have more developed organ systems. They have higher nervous system, which is divided into central and peripheral nervous system.
What kind of symmetry can be found in vertebrates and why?
As our bodies develop they mostly display bilateral symmetry across the vertebral column. A new molecular pathway, which plays a role in this symmetry in vertebrates, has recently been discovered. Some of our organs, such as the liver and the heart, are lateralised.
Do vertebrates have radial symmetry?
A vertebrate is an animal with a backbone. Most vertebrates have bilateral symmetry. Invertebrates can have bilateral or radial symmetry, or they can be asymmetrical. … Radial symmetry means the body parts are arranged in a circle around a central point.
Why are most animals bilaterally symmetrical?
Having bilaterally symmetrical bodies (the same on both sides along an axis) permit them to propel forward in a straight line. In evolutionary history, animals that moved quickly and efficiently from point A to point B would have been more successful and selected for than those who were ineffective at locomoting.
What classifies something as an animal?
animal means a vertebrate animal, and includes a mammal, bird, reptile, amphibian and fish, but does not include a human being.
What are four ways you can classify animals?
What are four ways that you can classify animals? Animals can be classified by how they look, what they eat, where they live, and how their babies are born.
What are the seven classification of animals?
There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. In addition, domain (proposed by Carl Woese) is now widely used as a fundamental rank, although it is not mentioned in any of the nomenclature codes, and is a synonym for dominion (lat.
Which animal has tube within tube body plan?
The tube within a tube is the annelid body plan. This means that in the coelomic cavity there is a superficial blanket of muscle, epidermis, and cuticle and an internal blanket of the digestive system. Hence, the correct answer is option D- Annelida.
Which worms body plan is referred to as a tube within a tube *?
The Phylum Rotifera | The Tube–within-a-tube Body Plan: Phylum Nematoda | Learning Objectives | Terms.
What is meant by tube within a tube construction?
Most animals have a body plan best described as a “tube–within-a-tube“. This plan calls for two openings: one for food to enter the body (mouth), one for wastes to leave the body (anus). The tube–within-a-tube plan allows specialization of parts along the tube, such as a stomach, intestine, etc.
Why are earthworms called a tube within a tube?
An earthworm burrows along using two sets of muscles. One set of muscles runs around the body, with one muscle in each segment. When the segment muscles tighten, the body becomes longer and thinner. … Earthworms, like all annelids, can be called a tube within a tube.
What does tube within a tube mean?
Most animals have a body plan best described as a “tube–within-a-tube“. This plan calls for two openings: one for food to enter the body (mouth), one for wastes to leave the body (anus). The tube–within-a-tube plan allows specialization of parts along the tube, such as a stomach, intestine, etc.

Which of the animal has tube within tube body plan?
The tube within a tube is the annelid body plan. This means that in the coelomic cavity there is a superficial blanket of muscle, epidermis, and cuticle and an internal blanket of the digestive system. Hence, the correct answer is option D- Annelida.
Do worms have eyes?
No, not really. Instead, they have cells called receptors that can sense whether it’s light or dark.
Which of the animal has tube within tube body plan?
The tube within a tube is the annelid body plan. This means that in the coelomic cavity there is a superficial blanket of muscle, epidermis, and cuticle and an internal blanket of the digestive system. Hence, the correct answer is option D- Annelida.
