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
cell-covered, fluid filled ball
structure made up of two layers of cells with an opening at one end
layer of cells on the outer surface of the gastrula; develops into skin and nervous tissue of animal
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
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
type of animal whose gastrula opening deveops into a mouth
type of animal whose mouth develops from cells other than the opening of the gastrula
