What are the 4 body plans?
Animal Body Planes and Cavities A midsagittal plane divides the body exactly in the middle, making two equal right and left halves. A frontal plane (also called a coronal plane) separates the front from the back. A transverse plane (or, horizontal plane) divides the animal into upper and lower portions.
What are the three types of body plans?
Animals can be classified by three types of body plan symmetry: radial symmetry, bilateral symmetry, and asymmetry.
What is the best description of a body plan?
A body plan is a group of structural and developmental characteristics that can be used to identify a group of animals, such as a phylum. All members of a particular group share the same body plan at some point during their development—in the embryonic, larval, or adult stage.
What is the basic body plan of animals explain?
At a very basic level of classification, true animals can be largely divided into three groups based on the type of symmetry of their body plan: radially symmetrical, bilaterally symmetrical, and asymmetrical. All types of symmetry are well suited to meet the unique demands of a particular animal’s lifestyle.

What is the human body plan?
The human body plan is bilateral with symmetrical sense organs, a fast responding brain, half the body weight in muscles, a powerful heart, and miles of arteries and veins and a brain that coordinates it all. All large active animals have this same body plan.
What are the 2 main body plans for animals?
Animal body plans follow set patterns related to symmetry. They can be asymmetrical, radial, or bilateral in form. Asymmetrical animals are those with no pattern or symmetry, such as a sponge.
