Structure and function

The performance expectations in Topic 2: Structure and Function help students formulate an answer to the question:

How do the structures of organisms enable living organisms to function?

Students investigate explanations for the structure and function of cells as the basic units of life, the hierarchical systems of organisms, and the role of specialized cells for maintenance and growth. Students demonstrate understanding of how systems of cells function together to support the life processes by reading critically, using models, and conducting investigations. 

Students who demonstrate understanding can: 

• LS1-1: Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells

• LS1-2: Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms

• LS1-3: Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis

• LS1-6: Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules
