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
