What is the consequence of having radial symmetry?

Radial symmetry is the arrangement of body parts around a central axis, as is seen in a drinking glass or pie. Only a few animal groups display radial symmetry. It results in animals having top and bottom surfaces but no left and right sides, or front or back.

Which is the greatest advantage of radial symmetry?

One advantage of radial symmetry is that it may make it easier for organisms to regenerate lost body parts. Sea stars, for example, can regenerate a lost arm or even an entirely new body as long as a portion of their central disk is still present.

What do you think is the advantage of having radial symmetry?

Radial symmetry is advantageous to sedentary organisms because sensory receptors are evenly distributed around the body. ... For sessile (sedentary) organisms, radial symmetry is useful because the animal can just "sit down" and grab food or detect threats from all directions.

What is the advantage of bilateral symmetry compared to radial symmetry?

The advantages of bilateral symmetry include the formation of a head and tail region, where the head region can house a detailed nervous system, and more directional movement to include the ability to move straight forward.

How do bilateral symmetry radial symmetry and asymmetry affect the feeding habits of an animal?

Their bodies are shaped irregularly like some animals including most sponges they lack any symmetry. How do bilateral symmetry radial symmetry and asymmetry affect the feeding habits of an animal? It may change habits because they have different body parts.

Do animals with radial symmetry have a head?

An animal with radial symmetry really has no right and left side or head and rear end. Radial symmetry is ideal for animals that do not move, so they can reach into their environment on all sides. Consider the starfish as an example of radial symmetry.

Does a sponge have radial symmetry?

Sponges are unsymmetrical or radially symmetrical, with many cell types but no distinct tissues; their bodies contain numerous pores and sharp protective spicules. Coelenterates (phylum Cnidaria) are radially symmetrical, with two tissue layers (ectoderm and endoderm) surrounding an all-purpose gastrovascular cavity.

What is the evolutionary significance of radial symmetry?

The radial body symmetry will be ideal for these animals because it confers on the body the ability to react to environmental forces in every direction (sessile cnidarians and echinoderms), to be able to catch food around with the same probability (cnidarians, ctenophores, echinoderms) and to maintain a static position ...

How do radial symmetry and bilateral symmetry differ?

The balanced distribution of the body shapes is referred to as the biological symmetry. ... The key difference between radial and bilateral symmetry is that radial symmetry generates identical body halves around the central axis whereas bilateral symmetry generates only two sides as left and right.

What are the advantages of radial symmetry to a sessile or slow moving organism?

Radial symmetry is advantageous to the slow-moving organisms as in these organisms there is even distribution of all the sensory receptors all over the body. As a result these animals can detect threats from all the directions. Animals with radial symmetry can grab food from all the directions.

Should animals with radial symmetry be better able to do than those with bilateral symmetry?

What should animals with radial symmetry be better able to do than those with bilateral symmetry? Deal effectively with food distributed homogeneously in 360 degrees.

What animals show radial symmetry?

Animals in the phyla Cnidaria and Echinodermata generally show radial symmetry, although many sea anemones and some corals within the Cnidaria have bilateral symmetry defined by a single structure, the siphonoglyph.

Which of the following animals is not radially symmetrical?

The correct answer is Physalia. Physalia is bilaterally symmetrical. Asterias, Cucumaria, Limulus has radial symmetry.

How can bilateral symmetry be an advantage to an animal?

In addition to having a more developed nervous system, bilaterally symmetrical animals can move more quickly than animals with other body plans. This bilaterally symmetrical body plan may have evolved to help animals better find food or escape predators.

Why is symmetry important to animals?

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.

How does an animal with bilateral symmetry differ from an animal with radial symmetry?

Explanation: The bilateral symmetry animals body are divided into two equal halves from a particular radius passing through the centre. The direction of cutting is fixed. ... The radial symmetry animals body are cut into two equal halves from all the radii of the animals body passing through the centre.

Which animal lacks symmetry has no embryonic tissues and has intracellular digestion?

Lacking a true digestive system, sponges depend on the intracellular digestive processes of their choanocytes for their energy intake.
