What is vertebrate and the vertebrate body plan?
A body plan, Bauplan (German plural Baupläne), or ground plan is a set of morphological features common to many members of a phylum of animals. The vertebrate body plan is one of many: invertebrates consist of many phyla. Evolutionary developmental biology seeks to explain the origins of diverse body plans.
Which are animal body plans?
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?
noun. Biology. the basic shape of members of an animal phylum; the general structure each individual organism assumes as it develops.Compare bilateral symmetry, radial symmetry.
What are the different types of body plan?
Answer: Animals can be classified by three types of body plan symmetry: radial symmetry, bilateral symmetry, and asymmetry.
What is the body plan of vertebrates?
All vertebrates are built along the basic chordate body plan: a stiff rod running through the length of the animal (vertebral column), with a hollow tube of nervous tissue (the spinal cord) above it and the gastrointestinal tract below.
What are the 2 main body plans for animals?
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.
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 body plan of a sponge?
The most basic body plan is called asconoid. In asconoid sponges the two major cell layers surround a fluid-filled cavity called the spongocoel, the large central cavity of sponges .
What are the 3 types of body symmetry?
What are the 5 main classes of vertebrates?
The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds. Show examples of these groups and explain the characteristics that make one different from another.
What makes vertebrates unique?
Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
Is a jellyfish radial or bilateral?
Because of the circular arrangement of their parts, radially symmetrical animals do not have distinct front or back ends. They may have distinct top and bottom sides. Some examples of these animals are jellyfish, sea urchins, corals, and sea anemones. A bicycle wheel also has radial symmetry.
What kind of body plan does a vertebrate have?
The vertebrate body plan is one of many: invertebrates consist of many phyla. This term, usually applied to animals, envisages a “blueprint” encompassing aspects such as symmetry, segmentation and limb disposition. Evolutionary developmental biology seeks to explain the origins of diverse body plans.
What makes a mammal different from other vertebrates?
Mammals are vertebrates that possess hair and mammary glands. Several other characteristics are distinctive to mammals, including certain features of the jaw, skeleton, integument, and internal anatomy. Modern mammals belong to three clades: monotremes, marsupials, and eutherians (or placental mammals).
What are the most important characteristics of a mammal?
MAMMALIAN CHARACTERISTICS. Many of the most important and diagnostic mammalian characteristics serve to further intelligence and sensibility, promote endothermy, or to increase the efficiency of reproduction or the securing and processing of food. Basic structural body plan is inherited from Therapsid mammal-like reptiles.
Are there any living organisms with body plans?
The current range of body plans is far from exhaustive of the possible patterns for life: the Precambrian Ediacaran biota includes body plans that differ from any found in currently living organisms, even though the overall arrangement of unrelated modern taxa is quite similar.
