Kingdom Animalia


2/55

~ Characteristics ~

Multicellular

Eukaryotic with no cell walls

Heterotrophs (consumers)


3/55

~ Characteristics ~

Have a nervous system to respond to their

environment

Locomotion relates to ability to obtain food

Most animals develop from a zygotebecoming a

A single layer of cells surrounding a fluid-filled space forming a hollow ball of cellscalled a gastrula.


4/55

~ Developmental Characteristics ~

The gastrula ismade up of three parts:

Ectoderm, a layer of cells on the outer surfaceof the gastrula,grows and divides developinginto skin and nervous tissue.

Endoderm, a layer of cells lining the innersurface of the gastrula,develops into thelining of the animals digestive tract.

Mesoderm, made up of two layers of cellslying between the ectodermand endoderm,forms muscles, reproductive organs and

circulatory vessels.

~ Developmental Characteristics ~

Animals that develop a mouth from theindented space in the gastrula areprotostomes.

Animals that develop an anus from theopening in the gastrula aredeuterostomes.

9/55

~ Body Plans ~

An animal has radial symmetryif itcan be divided along any plane,through a central axis, into equal

halves.

An animal has bilateral symmetryif

it can be divided down its lengthinto similar right and left halvesforming mirror images of each other.


10/55

Which figure has bilateral symmetry?

Which has radial s mmetr ?


11/55

~ Body Plans ~

Acoelomatesanimals have three celllayers with a digestive tract but no bodycavities.

Pseudocoelomatesanimals with a fluid-filled body cavity partly lined with

mesoderm.

Coelomatesanimals with a body cavitycompletely surrounded by mesoderm.

~ Protection and Support ~ Though not all animals have a skeleton,

those that do can be divided into twogroups:

Those with an exoskeletona hard,waxy coating on the outside of the body

that protects internal organs, provides aframework for support, and a place formuscle attachment.

Those with an endoskeletonsupportframework within the body that protectssome organs and a brace for muscles to

pull against.

~Invertebrates~

8 main phyla

No backbones

95% of all animals are in this group
