The Kingdom Animalia
(Latin: anima = “vital breath”, “soul”)
Classification of Animals:
Animals can be classified based on the following features:
- _______________
- _______________
- _______________
- _______________
- _______________
1) Level of Organization:
- _______________ level of organization = just cells, not organized into tissues
- _____________ level of organization = cells organized into tissues, no organs
- Have 2 germ layers
- _______________ = inner layer of cells
- _______________ = outer layer of cells
- _______________ 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:
- _______________ = an incomplete digestive system with only one opening which serves the function of both the mouth and the anus
- _______________ = 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:
- _______________ = The animal’s body does not have any symmetry
- _______________ = 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.
- _______________ = 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 _______________.
- _______________:
- No coelom develops
- _______________:
- There is a body cavity (the _______________) between the digestive tract and the body wall but it is not lined with a _______________
- _______________:
- 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
