From Molecules to Organisms: Structure and Processes

Performance Expectations

LS1: help students formulate an answer to the question, “How do organisms live and grow?” The LS1 Disciplinary Core Idea from the NRC Framework is presented as three subideas: Structure and Function, Growth and Development of Organisms, and Organization for Matter and Energy Flow in Organisms. In these performance expectations, students demonstrate that they can use investigations and gather evidence to support explanations of cell function and reproduction. They understand the role of proteins as essential to the work of the cell and living systems. Students can use models to explain photosynthesis, respiration, and the cycling of matter and flow of energy in living organisms. The cellular processes can be used as a model for understanding of the hierarchical organization of organism. Crosscutting concepts of matter and energy, structure and function, and systems and system models provide students with insights to the structures and processes of organisms.

SCI-HS.LS1.04 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.

Clarification Statement: Emphasis is on conceptual understanding that mitosis passes on genetically identical materials via replication, not on the details of each phase in mitosis.
Disciplinary Core Ideas
LS1.B: Growth and Development of Organisms -In multicellular organisms, individual cells grow and then divide via a process called mitosis allowing the organism to grow. Each parent cell passing identical genetic material to both daughter cells. Cellular division and differentiation produce and maintain a complex organism.
