What type of body plan is found in most animals?

Most animals are bilaterally symmetrical with a line of symmetry dividing their body into left and right sides along with a “head” and “tail” in addition to a top and bottom. Only sponges (phylum Porifera) have asymmetrical body plans.

What kind of body plan do most animals have?

Animals (mostly aquatic) with an up-and-down orientation have a radial symmetry in which there is no definite right or left side, but any longitudinal plane cut produces equal halves. Animals, either aquatic or terrestrial, that have a high level of mobility usually have a body plan that is bilaterally symmetric.

What is the body plan of animals?

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 makes up an animal's body?

Almost all animals have bodies made of differentiated tissues, which in turn form organs and organ systems. Animal bodies have evolved to interact with their environments in ways that enhance survival and reproduction.

Which animals have a sac body plan?

Sponges: The Phylum Porifera | Back to Top. The phylum Porifera ("pore-bearing") consists of approximately 5,000 species of sponges. These asymmetrical animals have sac-like bodies that lack tissues, and are usually interpreted as representing the cellular level of evolution.

What are the 2 main body plans for animals?

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 main body plans of animals?

Animals can be classified by three types of body plan symmetry: radial symmetry, bilateral symmetry, and asymmetry.

What are the four types of body plans?

Grouping animals with these body plans resulted in four branches: vertebrates, molluscs, articulata (including insects and annelids) and zoophytes or radiata.

What type of body plan do humans have?

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 three body plans?

The three planes of motion are the sagittal, frontal and transverse planes. Sagittal Plane: Cuts the body into left and right halves.

How many body system are found in animals?

Organ Systems in Animals

Encyclopædia Britannica, Inc. In the more advanced animals, there are usually 10 organ systems: integumentary (skin), skeletal, muscular, nervous, endocrine (hormonal), digestive, respiratory, circulatory, excretory (urinary), and reproductive.

What protects the bodies of animals answer?

Skin protects the body of animals .

Which animal has tube within a tube body plan?

Complete answer: The Tube-within-tube body plan is shown by the phylum Annelida. They are also known as ringed worms belonging to a large phylum with species including earthworms, ragworms, and leeches.

Which two organisms have a tube within a tube body plan?

The Tube-within-a-tube Body Plan: Phylum Nematoda | Back to Top. The Phylum Nematoda consists of several hundred thousand species of roundworms.

In which animal tube within tube structure is found?

Tube - within - tube body plan is shown by phylum Annelida. These are the characteristics of Annelida: Free-living, terrestrial or aquatic form (freshwater or marine).
