What are the four types of body plans?
They are asymmetrical, radial, or bilateral in form as illustrated in Figure 6.
What are body plan genes?
A group of genes known as homeobox (Hox) genes control embryonic development of the body plan in a wide range of animals, from humans and fruit flies to cats to beetles. Together, the combined Hox-TALE binds to the DNA of downstream genes and switches them on, setting the development of an antenna or a leg into motion.
What are six characteristics of the human body plan?
bilaterally symmetrical.
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.
What type of body plan do humans have?
bilateral
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 is an organisms basic body plan?
A body plan is a suite of characters shared by a group of phylogenetically related animals at some point during their development. Essentially, a body plan is a suite of characters shared by a group of phylogenetically related animals at some point during their development.
What is a basic body plan?
What are the different symmetries?
There are three types of symmetry: reflection (bilateral), rotational (radial), and translational symmetry.
Which is the best description of a body plan?
Body plan. Modern groups of animals can be grouped by the arrangement of their body structures, so are said to possess different body plans. 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.
How are animals classified according to their body plan?
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.
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.
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.
