Identify and list the characteristics of a mouse that make it a member of the animal kingdom.
|
It is a multicellular hetertroph, moves to get food, and has cells without cell walls.
|
|
Explain why movement is an important characteristic of animals.
|
Animals must serach for food and mates.
|
|
Compare and contrast a protostome and a deuterostome.
|
Protostomes: the mouth develops from the opening in the gastrula; deuterostomes: the mouth develops elsewhere on the gastrula.
|
|
Identify cell differentiation in the development of an animal.
|
Ectoderm: skin and the nervous system; Endoderm- digestive organs and the digestive tract's lining; Mesoderm:muscles, the circulatory, and excretory systems, and in some animals, the respiratory system.
|
|
Describe gastrulation.
|
Gastrulation occurs when cells of the blastula move inward and form an indentation on the surface of the blastula. It is now called a gastrula.
|
|
Name a land animal that is sessile. Why would this adaptation be a disadvantage to an animal in a land biome?
|
Scale insects mature as sessile animals after they pierce plant tissues with their mouths to feed on plant liquids. A sessile land animal could not locate a mate or find more food if its current food source (the host) disappeared.
|
|
Make a concept map of animal development using the following stages, beginning with the earliest stage: gastrula, larva, adult, fertilized egg, blastula.
|
fertilized egg, blastula, gastrula, larva, adult
|
|
organisms that are permanently attached to a surface
|
sessile
|
|
cell-covered, fluid filled ball
|
blastula
|
|
structure made up of two layers of cells with an opening at one end
|
gastrula
|
|
layer of cells on the outer surface of the gastrula; develops into skin and nervous tissue of animal
|
ectoderm
|
|
layer of cells lining the inner surface of the gastrula; develops into the lining of the animal's digestive tract and the organs associated with the digestive tract
|
endoderm
|
|
third cell layer found in the developing embryo between the ectoderm and the endoderm that develops into muscles, circulatory system, excretory system, and, in some animals the respiratory system
|
mesoderm
|
|
type of animal whose gastrula opening deveops into a mouth
|
protostome
|
|
type of animal whose mouth develops from cells other than the opening of the gastrula
|
deuterostome
