Unformatted text preview: Theme : Life is Characterized by a High Level of Order and Complexity
• Concept A: Biological order and complexity is instructed; they are derived from the information content of DNA • Concept B: Biological systems exhibit emergent properties. • Concept C: The purpose of exchange of matter and energy is the maintenance of order and complexity. Theme: Biological Structure and Function are Coupled
• Concept A: Structure optimizes physiological processes. • Concept B: Specialized structures (e.g., eye, voice box) support specialized functions • Concept C: Diseases are aberrations of normal structure and/or function Cells: Basic Units of Life
hepatocyte Mitosis and differentiation
Copyright Dennis Kunkel Microscopy, Inc. • Cells are the smallest units capable of carrying out most of the processes associated with life and are the basic units of structure and function in the animal and plant body • During development, a single cell (the fertilized egg) undergoes division and the derived cells differentiate to become functionally distinct, highly specialized cells • There are hundreds - thousands of different cells types in the human body that can be identified in terms of differences in structure and function The human body is an aggregate of ~...
