Give an overview of animals
- multicellular
- eukaryotic
- heterotrophic
- no cell wall present
- consisted of highly differentiated cells
Name the characteristics of animals
- symmetry
- body cavity
- digestive tract
- circulatory system
Name the types of symmetry
- radial
- bilateral
- asymmetrical
What is radial symmetry?
symmetry around a center point
i.e. starfish
What is bilateral symmetry
symmetry across a medial line
i.e. humans
What is asymmetrical symmetry?
no symmetry
Name the types of body cavities
- acoelomate
- psuedocolomate
- coelomate
What is acoelomate?
- no body cavity
- space filled with mesoderm
What is pseudocoelomate?
- body cavity lies between endoderm and mesoderm
What is coelomate?
- body cavity is lined with mesoderm
Types of digestive tract
- single
- double
Types of circulatory system
- open
- closed
Identify
- Phylum porifera
- i.e. Scypha
What is an osculum?
- large opening on a sponge
What is a collar cell?
- closely resembles a flagellum
- collective beating moves water through
Describe a general phylum cnideria
- tissue grade level of organisation
