Vertebrates and Invertebrates
The organization of an animal’s cells into higher levels of structure include
Cells, tissues, organs, and organ systems
Jellyfishes and corals are examples of_______ which are invertebrates that have stinging cells and take food into a central body cavity.
All Chordates have three characteristics:
A notochord, a nerve cord, and pouches in the throat area.
A____ is a vertebrate that lives in water and uses fins to move.
Animals that have no symmetry. (like sponges)
DAILY DOUBLE- Flatworms have flat, soft bodies. Roundworms look like smooth, thin tubes. Segmented Worms have bodies made up of many linked sections called segments. What category of invertebrates are these
A_______ is a flexible rod that supports a chordate’s back.
An_________ is a vertebrate that is ectothermic and spends its early life in water and its adult life on land.
1. Obtain food and oxygen
2. Keep internal conditions stable
3. Move in some way
4. Reproduce
An animal that has MANY imaginary lines that can be drawn through a central point to divide it into two mirror images. (like a jellyfish)
An________ is an invertebrate that has an internal skeleton and a system of fluid-filled tubes.
The backbone is made up of a stack of many small bones called
Vertebrae
A_______ is an ectothermic vertebrate that has scaly skin and lungs and lays eggs on land.
DAILY DOUBLE- Animals are classified according to how they are related to other animals. How are these relationships determined
By an animal’s body structure, the way the animal develops, and its DNA.
Animals that only have one line of symmetry that can be drawn to divide it into halves that are mirror images. (like humans)
Invertebrates with soft, unsegmented bodies that are often protected by a hard shell are called
Amphibians, reptiles, and most fish are_________ (animals that produce little internal body heat)
Ectotherms
A_____ is an endothermic vertebrate that lays eggs
and has feathers and a four-chambered heart.
All animals are what
Multicellular organisms that feed on other organisms and perform the same basic functions.
The bodies of animals without symmetry are organized simply. Animals with radial symmetry have complex body plans with tissues and usually with organ systems. Animals with bilateral symmetry have what
Organ systems and are usually larger and more complex than animals with radial symmetry.
_________ are invertebrates that have hard outer coverings, segmented bodies, and pairs of jointed appendages.
Birds and mammals are__________ (animals that control the internal heat they produce and regulate their own temperature)
Endotherms
_________ are endothermic vertebrates that have skin covered with fur or hair, and a four-chambered heart. Their young are fed with milk.
