The Kingdom Animalia

(Latin: anima = “vital breath”, “soul”)

Classification of Animals:

Animals can be classified based on the following features:

1. _______________
2. _______________
3. _______________
4. _______________
5. _______________

1) Level of Organization:

1. _______________ level of organization = just cells, not organized into tissues
2. _____________ level of organization = cells organized into tissues, no organs

• Have 2 germ layers
  • _______________ = inner layer of cells
  • _______________ = outer layer of cells

1. _______________ level of organization = tissues organized into organs

• Have 3 germ layers
  • _______________ = inner layer of cells
  • _______________ = outer layer of cells
  • _______________ = middle layer of cells

The evolutionary trend is _____________ à ____________ à ____________

2) Type of Body Plan:

1. _______________ = an incomplete digestive system with only one opening which serves the function of both the mouth and the anus
2. _______________ = a complete digestive system with two openings – a mouth for food input and an anus for waste output

The evolutionary trend is _______________ à _______________

3) Type of Body Symmetry:

1. _______________ = The animal’s body does not have any symmetry
2. _______________ = Similar body parts are arranged around a central axis, like a whirl

• They can have many planes of symmetry
• ANY longitudinal slice from mouth to anus will produce equal halves
• Tend to be _______________ = stay in one place throughout adult life.

1. _______________ = Has two equal halves

• They can only have one plane of symmetry
• Have _______________ and _______________ ends as well as _______________ and _______________ sides
• Tend to be _______________ which means they are active and move forward with the anterior end
• has usually led to _______________ = the process by which sensory organs and appendages became localized in the head end of animals.

The evolutionary trend is _______________ à _______________ à ____________

4) Type of Coelom

A coelom is an internal body cavity that develops from the _______________ tissue layer during an animal’s development. This cavity lies between the digestive tract and the body wall, and is lined by _______________ which make up the _______________.

1. _______________:

• No coelom develops

1. _______________:

• There is a body cavity (the _______________) between the digestive tract and the body wall but it is not lined with a _______________

1. _______________:

• There is a body cavity between the digestive tract and the body wall that is lined with a _______________ (a “true coelom”).

The evolutionary trend is _______________ à _______________ à ____________

5) Segmentation:

Segmentation = the ______________________________________________ _____________________________. This can lead to specialization of body parts because various segments become differentiated for specific purposes.

The evolutionary trend is towa
