Define symmetry:
A arranged in such a way that you cannot divide them into equal halves.
B Any animal with a backbone.
C is the balanced arrangement of body parts around a center point or center line.
D Any animal without a backbone.
C the balanced arrangement of body parts around a center point or center line.
Radial symmetry is defined as when body parts are arranged in a circle around a center point.
Give an example
Jellyfish, starfish
____ of a vertebrate are part of the living tissue of the animal and they grow with the animal.
Bones
The bones support the body of the animal and protect_____
vital organs
Some Invertebrates have an _______which is a hard outer covering.
exoskeleton
Animals do not grow beyond
a. birth
b. adult
c. they never stop growing
d. their 7th birthday
B. certain adult size
Bilateral symmetry- when an animal has its exterior body parts arranged the same way on both sides of its body.
Give an example
human, dog, cat
The vertebrae also support and protect the______
spinal cord
What are the two animal classifications?
Invertebrates and Vertebrates
bilateral symmetry is for the
a. interior
b. exterior
c. both interior and exterior
d neither interior or exterior
B Exterior only
What would be an example of locomotion?
run, jump, swim, fly, crawl, hop, slither
Asymmetrical animals have their body parts arranged in such a way that you cannot divide them into equal halves.
Give an example
halibut or fish with eyes on one side of body
elk or other horned animals
honey badgers (one side of their mouth has more teeth).
Define invertebrates
Invertebrates- Any animal that doesn’t have a backbone.
Define vertebrates
Any animal with a backbone
radial =body parts are arranged in a circle around a center point.
Bilateral=exterior body parts arranged the same way on both sides of its body.
What are the 3 of the 5 characteristics of an animal?
1. They have to take their food from the environment
2. Animals do not grow beyond a certain adult size.
3. They are multicellular
4. They move from place to place which is called locomotion.
5. Some creatures only move at a certain time in their life and then they anchor as an adult.
What are the four anatomical positions?
Anterior-front end of an animal
Posterior- back end of an animal
Dorsal-upper side of the animal
Ventral- under side of the animal
What are the three characteristics of a vertebrate?
Vertebrates-
Bones of a vertebrate are part of the living tissue of the animal and they grow with the animal.
The bones support the body of the animal and protect vital organs.
The vertebrae also support and protect the spinal cord.
What three things does the body of the Vertebrates protect?
1. support the body of the animal
2. protect vital organs.
3. support and protect the spinal cord.
Give 3 examples of invertebrates
butterflies, corals, worms, octopi, starfish, jellyfish, grasshoppers, clams
