Chapter 4 animals

Lesson 2

TermDefinition
Tissue A group of similar cells that perform a specific function
Organ A body structure that is composed of different kinds of tissues that work together
Radial symmetry A body plan in which any number of imaginary lines that all pass through a central point point divide the animal into two mirror images
Bilateral symmetry A body plan in which a single imaginary line divides the body into left and right sides that are mirror images of each other
Describe an animals body body plan The organization of an animal’s cells into higher levels of structure, including tissues, organs, and organ systems, helps to describe an animal‘s body plan.
Describe how the structures of animals are related to their symmetry The bodies of animals without symmetry are organized simply, with some specialized cells, but no tissues. Animals with radial symmetry have complex body plans with tissues and usually with organ systems. Animals with bilateral symmetry have organ systems.
Describe what asymmetrical body type means and give an example of an animal Animals that are asymmetrical are organized simply with some specialized cells, but no tissues. Sponges are asymmetrical animals.
Describe what radial symmetry means and give an animal example Animals with radial do not have a head or specialized sense organs, allowing them to take in information about their surroundings from all directions. Jellyfish have radial symmetry.
Describe what bilateral body symmetry means and given an animal example Animals with bilateral symmetry have complex organ systems and specialized sense organs. They are the most complex type of animal. Humans, butterflies, dogs are just a couple of them.
