Certain animals have their body parts arranged around a central point. A starfish is a good example of this, which is known as radial symmetry.

What does asymmetry and radial symmetry have in common?
Animals with radial symmetry have body parts arranged around a central point. Any line drawn from one side through the center to the opposite side will divide the animal into two symmetrical halves.
If a circle was divided into 6 equal parts what would be the degree measure of the central angle?
It is 60 degrees
What is oral-aboral axis?
termed the oral, or anterior, end, and the other of which, called the aboral, or posterior, end, forms the rear end of the animal and may bear the anus. The main axis is hence termed the oral-aboral, or anteroposterior, axis. Except in animals having an odd number of parts arranged in circular fashion (as in the five-armed starfishes), any plane passing through this axis will divide Or basically if you want to look at it, oral means cutting the organism horizontally and aboral means cutting the organism vertically.
Who stated that the sum was not equal to all of its parts?
That is part of a psychology knownas "gestalt psychology", first promoted around 1900 by Christian von Ehrenfels. Its premise is that "the whole is greater than the sum of its parts"
How do you devide a circle into 7 equal parts?
A circular sector is formed by two radii and an arc. And the angle formed due to the two radii is central angle(Θ). Area of a sector = (Θ/360) πr2.If we divide a circle into seven sectors having equal central angles then the circle is divided into seven equal parts.Angle of the whole circle is 360o. So we should divide the whole angle into 7 equal parts each measuring 360o/7 and then forming the corresponding sectors.
Animals that have their body parts arranged around a central point are said to be?
radially symmetric
Animal with body parts arranged in a circle around a central point are?
Radial Symetry :)
Symmetry in which body parts are arranged in a circle around a central point?
radial symmetry
What type of symmetry in which body parts are arranged in a circle around a central point?
Radial Symmetry .
What is a Coelenterate?
A group of primitive aquatic animals that include jellyfish, corals, and sea anemones. Colenterates are sessile (sedentary) and exhibit symmetry. Their body parts are symmetrically arranged around a central point.
What Animal whose bodies are arranged a central point have what type of symmetry?
Animals with radial symmetry have body parts that are arranged around a central point. Any line drawn from one side through the center to the opposite side will divide the animal into two symmetrical halves. Because of their circular arrangement, radially symmetrical animals donâ??t have a recognizable front or back end, but they may have distinct tops and bottoms.
What does asymmetry and radial symmetry have in common?
Animals with radial symmetry have body parts arranged around a central point. Any line drawn from one side through the center to the opposite side will divide the animal into two symmetrical halves.
Which phylum includes animals that have radial symmetry and are often covered with spines?
The phylum Echinodermata includes animals with radial symmetry, such as sea stars, sea urchins, and sand dollars. These animals are often covered with spines and have a water vascular system that helps in movement and feeding.
What type of symmetry do cnidara have?
radial symmetry which means that all the parts of the body are arranged around a central axis in such a way that any plane passing through the central axis divides the animal in halves that are almost mirror image of each other
How are the parts of an organism arranged?
how are the body parts of an organism arranged
What is the difference between radial symmetry and spherical symmetry?
In spherical symmetry, body parts radiate out from a central point; an infinite number of planes passing through the central point can divide a spherically symmetrical organism into similar halves. In Radial symmetry, body parts are arranged around one main axis at the body's center.
What is it called when body parts are arranged like spokes around the hub on a bicycle wheel?
polyp
