Vocabulary
An animal with a backbone.
What is a Vertebrate
An animal that controls the internal heat it produces and regulates its own body temperature.
What is an Endotherm?
All animals are classified by how they are related ot eachother. All animals are either Vertebrates or Invertebrates.
What are all animals and how are they classified?
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.
What are the levels of organization an animal has in their body structure?
About 96% of known animals are invertebrates.
They live in every climate.
What percent of invertebrates are there?
An animal without a backbone.
What is an Invertbrate?
A framework that shapes and supports the animal, protects its organs, and allows it to move.
What is a Skeleton?
All animals are multicellular organisms that feed on other organisms and perform the same basic functions.
What type of organism are animals?
animals with radial symmetry have complex body plans with tissues and usually with organ systems.
what is the organization of an animal with radial symmetry?
are asymmetrical invertebrates. They have
some specialized cells but no tissues or organs.
What are sponges?
An animal that can have lines drawn through a central point to divide to divide it into two mirror images.
What is Radial Symmetry?
Places where two or more parts of a skeleton meet.
What is a Joint?
The main functions of an animal are to obtain food and oxygen, keep internal conditions stable, move in some way, and reproduce.
What are animals main functions?
The bodies of animals without symmetry are organized simply.(They don't have a specific organization.)
What type of organization do animals with no symmetry have?
invertebrates that have stinging cells and
take food into a central body cavity.
What are CNDINARIANS?
An animal that can have only one line of symmetry drawn to divide into halves that are mirror images.
What is Bilateral Symmetry?
Tissues that contract or relax to make movement.
What are Muscles?
Animals with bilateral symmetry have organ systems and are usually larger and more complex than animals with radial symmetry.
What level of organization does an animal with Bilateral Symmetry have?
Have flat soft bodies,look like smooth thon tubes, and have bodies made up of many linked sections called segments.
What are Flatworms,Roundworms, and Segmented worms?
An animal that produces little internal body heat.
What is an Ectotherm?
an invertebrate that has an internal skeleton and a system of fluid-filled tubes.
Invertebrates with soft, unsegmented bodies that are often protected by a hard shell.
invertebrates that have hard outer coverings,segmented bodies, and pairs of jointed appendages.
What is an Echinoderm?
What is a Mullusk?
What is an Arthropod?
