Unit 1 - Basic Biological Principles

This unit examines the nature of life, the characteristics of living things, and the relationship between structure and function from the organelle to the multicellular organism. How do we know if something is alive? How is structure related to function at the various levels of cellular organization? This unit comprises 5% of the information on the Keystone Exam. 

Objectives: 
1.) Describe the characteristics of life shared by all prokaryotic and eukaryotic organisms.
2.) Compare cellular structures and their functions in prokaryotic and eukaryotic cells.
3.) Describe and interpret relationships between structure and function at various levels of biological organization(i.e. organelles, cells, tissues, organs, organ systems, and multicellular organisms).

Questions you should be able to answer: 

1.) What are the common characteristics exhibited by all living things – both prokaryotic and eukaryotic? 
2.) What are the similarities and differences in structure between prokaryotic and eukaryotic cells? 
3.) What are some common features and functions of cell structures in both prokaryotic and eukaryotic cells? 
4.) What are the levels of biological organization from organelle to organism? 
5.) What is the relationship between structure and function at the organelle, cell, tissue, organ, organ system and multicellular organism level of organization?
