The Biogenetic Law
Characterizes unicellular organisms
Protoplasmic level of organization
Denotes an aggregation of undifferentiated cells
Cellular level of organization
At this level, similar cells aggregate into definite patterns of layers, thus becoming a tissue..
Cell-tissue level of organization
Organs usually contain more than one kind of tissue and have specialized function than tissue
Tissue-organ level of organization
When organs work together to perform some function, they form a complex level of organization
Organ-system level of organization
- Protoplasmic level of organization
- Cellular level of organization
- Cell-tissue level of organization
- Tissue-organ level of organization
