Biology U3 L01 Typical Animal Characteristics

Front 1

Identify and list the characteristics of a mouse that make it a member of the animal kingdom.

Back 1

It is a multicellular hetertroph, moves to get food, and has cells without cell walls.

Front 2

Explain why movement is an important characteristic of animals.

Back 2

Animals must serach for food and mates.

Front 3

Compare and contrast a protostome and a deuterostome.

Back 3

Protostomes: the mouth develops from the opening in the gastrula; deuterostomes: the mouth develops elsewhere on the gastrula.

Front 4

Identify cell differentiation in the development of an animal.

Back 4

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.

Front 5

Describe gastrulation.

Back 5

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.

Front 6

Name a land animal that is sessile. Why would this adaptation be a disadvantage to an animal in a land biome?

Back 6

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.

Front 7

Make a concept map of animal development using the following stages, beginning with the earliest stage: gastrula, larva, adult, fertilized egg, blastula.

Back 7

fertilized egg, blastula, gastrula, larva, adult

Front 8

organisms that are permanently attached to a surface

Back 8

sessile

Front 9

cell-covered, fluid filled ball

Back 9

blastula

Front 10

structure made up of two layers of cells with an opening at one end

Back 10

gastrula

Front 11

layer of cells on the outer surface of the gastrula; develops into skin and nervous tissue of animal

Back 11

ectoderm

Front 12

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

Back 12

endoderm

Front 13

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

Back 13

mesoderm

Front 14

type of animal whose gastrula opening deveops into a mouth

Back 14

protostome

Front 15

type of animal whose mouth develops from cells other than the opening of the gastrula

Back 15

deuterostome
